Definition of EVA Foam

Ethylene-vinyl acetate (EVA) foam, often referred to as foam rubber, is a versatile foam material with a closed-cell structure. This closed-cell foam is part of the wider family of foam materials and boasts properties like excellent shock absorption, moisture resistance, and resistance to chemicals. EVA foam comes in various types and is widely utilized in industries ranging from footwear and sports equipment to packaging and cosplay, making it a popular choice for applications requiring lightweight, flexible, and durable foam materials.

What is the difference between closed-cell foam and open-cell foam?

Characteristics of EVA Foam

EVA foam is a versatile material with a wide range of characteristics that make it suitable for various applications. Here are the key characteristics of EVA foam:

  • Low Water Absorption: EVA foam is well-known for its low water absorption, making it ideal for applications where exposure to moisture is a concern. Its closed-cell foam structure ensures that water cannot easily penetrate its surface.
  • UV Resistant: The resistance to UV radiation that EVA foam possesses makes it an extremely popular choice for products used outdoors. For example, fishing rods often have an EVA foam grip. 
  • Durability: EVA foam is exceptionally durable and can withstand repeated use and wear, making it a long-lasting material for various applications. Foam Creation's advanced EVA foam has an impressive durability and is lightweight.
  • Flexibility: It is a flexible material, which allows it to be easily molded into different shapes and sizes without losing its structural integrity.
  • Cushioning Properties: Compared to natural rubber, EVA foam offers superior cushioning properties. This makes it an ideal choice for applications where impact absorption is crucial, such as in foam mats and sports equipment.
  • Stress-Crack Resistance: EVA foam exhibits enhanced stress-crack resistance, ensuring that it remains in good condition even under demanding conditions.

The Manufacturing Process of EVA Foam

The manufacturing process of EVA foam involves a series of steps that transform raw materials into the versatile material known for its remarkable properties. Ethylene-vinyl acetate (EVA) copolymers, which are the primary raw materials, are first blended with additives like foaming agents and stabilizers to create a homogeneous mixture.

This mixture is then heated and extruded into sheets or rolls, which are subsequently processed using techniques like compression molding, injection molding, or foam sheet cutting to achieve the desired shapes and forms. The foam is then allowed to cool and cure.

The main disadvantage of the manufacturing process of EVA foam is the fact that most manufacturers are limited in what they can offer. They generally have set templates and limited scope for wider production, which means businesses have to outsource additional elements of the production process. At  Foam Creations, we offer a unique end-to-end service with immense flexibility. Thanks to our  advanced technology, we can manufacture any type of custom foam molding, hence eliminating the problems that occur with traditional EVA and other polyolefin foam manufacturing.

Applications of EVA Foam

EVA foam is the ideal material for a  wide variety of products. From protective gear to costume design, it is the ideal solution for diverse manufacturing needs. Below are some of the most common applications of EVA foam:

  • Sports Gear: From helmets to padding in equipment, EVA foam is widely used in the sporting industry. Its ability to absorb impacts makes it ideal for protecting athletes during high-intensity activities.
  • Shoes and sandals: EVA foam midsoles in athletic shoes and insoles in flip-flops offer cushioning, shock absorption, and arch support, enhancing comfort and performance.
  • Seats: EVA foam is used in boat and stadium seats for its water-resistant, durable, and comfortable properties, ensuring long-lasting support and cushioning for users.
  • Protective Gear: EVA foam liners in helmets, knee and elbow pads offer essential impact absorption for athletes and outdoor enthusiasts, enhancing safety during various activities.
  • Spas and Pool Areas: EVA foam is a go-to material for pool noodles, floats, and spa pillows, providing buoyancy, comfort, and waterproof features for relaxation and water-based activities.
  • Packaging and Transport: EVA foam creates protective packaging inserts and automotive insulation, safeguarding fragile items during shipping and reducing noise and vibrations in vehicles.
  • Yoga and Exercise Mats: EVA foam mats in yoga and exercise studios deliver comfort and support for practitioners during floor exercises and workouts.
  • Crafts and DIY Projects: EVA foam sheets are a versatile material for creative endeavors, including cosplay, costume design, and model building, offering ease of cutting, shaping, and gluing.
  • Children's Toys: EVA foam is a safe and soft material used in children's toys like building blocks and puzzles, ensuring both fun and safety during play.
  • Medical and Orthopedic Applications: EVA foam finds use in orthopedic insoles and prosthetic components, offering cushioning and support to individuals with specific foot and mobility needs, contributing to their well-being.

Tips for Caring and Maintaining EVA Foam Products

To keep your EVA foam products in good condition, be sure to store them in a cool and dry place away from direct sunlight. This will help prevent the foam from warping or degrading over time. 

In addition to proper storage, here are some tips for caring and maintaining your EVA foam products:

  • Clean regularly: Dust and dirt can accumulate on the surface of EVA foam so it's important to clean it regularly. Use a mild soap or detergent mixed with water and gently wipe down the foam using a soft cloth or sponge.
  • Avoid sharp objects: EVA foam is durable but can still get damaged by sharp objects. Avoid using excessive force that could cause tears or cuts in the material.
  • Protect from heat:  High-density EVA foam has excellent heat resistance but prolonged exposure to high temperatures can still cause damage. Avoid placing your EVA foam products near sources of heat like heaters or stoves.

Future Trends in EVA and Other Polyolefin Foam Technology

The future of polyolefin and EVA foam is poised for exciting developments. One prominent trend is the increasing demand for sustainable and eco-friendly foam materials, driven by the global shift towards greener practices. This can be seen in  Foam Creations' commitment to producing polyolefin foam that is not only lightweight, flexible, and exceptionally durable but also free from harmful substances like phthalates and heavy metals. 

Additionally, as technology advances, polyolefin foam is likely to be used in more complex and specialized applications, including those requiring advanced customization and high-performance characteristics, which  Foam Creations is already facilitating due to its advanced injection molding capabilities.

Home Gym: Foam vs Rubber

Ready to build your home gym, but don’t know where to start? We’ll give you the low down on foam vs rubber to help you choose between the big 2 gym flooring options. Learn the pros and cons of each and decide which is the best option for you.

If you’re anything like me, you might not have even heard about rubber or foam flooring until you embarked on this adventure towards 6 pack abs at home. Or, ya know, a healthier lifestyle at home.

For a long time, I would go to the gym regularly but never gave a second thought to what type of floor I was working out on or how someone would even go about buying flooring for a gym. Once you google for a hot minute, you can see that the two most common options for a home gym are rubber flooring and foam flooring.

Foam flooring is great for a first time home gym. Perfect for lightweight and bodyweight exercises, with plenty of cushion for your joints and an affordable sticker price, foam is a great place to start for your basic home gym!

You can use foam tiles or foam mats to create your ideal home sweat-space. Pick and choose different colored tiles to give a checkered or multi-colored look to your home gym. Foam can also double as a kids’ playroom, making it super versatile for families, and a great way for parents to workout at home with the kiddos!

Pros of Foam Flooring for Home Gyms

  • Lightweight. Foam is naturally light and incredibly easy to move. This makes installation a breeze, and you can even make a portable gym floor that can be taken up when you’re through with your workout.
  • Flexible and shock absorbent. That shock absorbency is great on your joints and helps protect your floor.
  • Soft. Because, have you ever tried doing floor exercises on a tile floor?
  • Waterproof. Spills and sweat are no problem – just simply wipe off the foam tiles and, voila, they’re good as new.
  • Excellent insulator. You won’t have to wear all those extra layers in the winter months! Foam keeps the warmth in and the cool air out.
  • Wide variety of colors. You can mix and match to create exactly the look you want.
  • Available in interlocking tiles or portable mats. Mats are great for a temporary fix, but tiles are super easy to install and great for a more permanent (but still easily movable) dedicated workout space.
  • Easy to install and keep clean. Mats require zero installation and interlocking foam tiles take only minutes. With both flooring options, they just require the occasional wipe down with a mild cleaning solution to stay fresh and sparkling.

Cons of Foam Flooring for Home Gyms

  • Will indent under heavy weights. Foam is soft and that softness is excellent for body weight workouts and light weights, but foam is not the best option for heavy lifting. You just need something a little more durable for your swole.
  • Less durable than rubber. Foam is cheaper and softer than rubber, but it is also (most of the time) less durable. It will definitely hold up to typical at-home workouts, but it won’t last you quite as long as rubber.
  • Can be punctured or scratched. Again, foam is soft, which makes it more susceptible to punctures, tears and scratches.

Best Uses for Foam Flooring in Home Gyms

  • Yoga
  • Bodyweight exercises
  • Stretching
  • Lightweight conditioning

Rubber flooring is a great choice for any home gyms and commercial gyms alike. With endless options and excellent durability, rubber is the #1 choice for gym flooring.

Rubber flooring is built to stand up to heavy cardio equipment, such as ellipticals, treadmills and the torturous stair machine (seriously, it never gets easier!), as well as plyometrics (jumping movements) and even the weight of heavy barbells. Choose from tiles, rolls and mats to create your dream gym.

Pros of Rubber Flooring for Home Gyms

  • Extremely durable. Unlike foam, rubber is built to handle your toughest workouts. You can really go ham on your rubber floor and it will take the abuse in stride!
  • Excellent insulator against sound transmission. Read –> it keeps things quiet.
  • Able to withstand heavy weight equipment. 600lb deadlifts? Treadmills? No problem! You want to make sure you go for the correct thickness if you will be dropping extremely heavy weights, but rubber can totally handle it.
  • Green options. Recycled rubber is great for the environment!
  • Available in easy to install interlocking tiles and low-cost rubber rolls. Tiles are a piece of cake to install, but rolls are (usually) less expensive. Either way, the floor is going to be durable and support you in all your workouts. The choice is whether you want a lower price point and longer installation or the ease of interlocking tiles with a little extra spend.
  • East to clean. Just like foam, all you have to do is wipe down your rubber floor every now and then with a mild cleanser and you’re good to go.

Cons of Rubber Flooring for Home Gyms

  • Rubber flooring is very heavy. This makes it challenging to move yourself, especially large rubber rolls.
  • Does not insulate well against temperature transmission. That means it won’t keep you warm the way foam can. Layer up.
  • Cost. Bright colored rubber is usually made from virgin rubber and can be more costly. Additionally, because rubber is so durable, it often costs a little more than foam in general.

Best Uses for Rubber Flooring In Home Gyms

  • Weightlifting
  • Plyometric movements
  • Olympic weightlifting
  • Underneath cardio equipment
  • Just about anything!

In Conclusion

Ultimately, only you can decide if rubber or foam is the best choice for you, but we can help you out a little. If you’re just getting into exercise and want something lightweight and inexpensive, you’ll do great with foam!

However, if you know you’re going to be working hard with heavy weights and explosive movements, you should bite the bullet and go for the rubber. It will last you longer and support you better in intense workouts.
