Is EVA foam flammable?

In this blog post, we will answer the question, “Is EVA foam flammable?”. We will also discuss what EVA foam is, the characteristics of EVA foam, what happens when you heat EVA foam, the uses of EVA foam, and the industrial chain of EVA foam.

Is EVA foam flammable?

No. EVA foam is not flammable. Its flash point is higher than 300oC, so it needs to be heated to a temperature above 300oC to cause a spark. Therefore, EVA foam is classified as a nonflammable material. 

What is EVA foam?

EVA FOAM is a vinyl-based synthetic foam. This foam is thick, with microscopic pores, light, elastic, not easily torn, and available in a range of colors. 

EVA foam also comes in various hardness ratings: h-35/40, h-45/55, and h-60/65.

EVA foam is widely utilized in the electronics, automobile, clothing & apparel, toy, and packaging industries.

Life jackets, swimming equipment, martial arts mats, foam mats, children’s educational toys, buoyancy media, engine bearings, product tool holders, product holders, and so on are some examples of items using EVA foam.

What is Ethylene-vinyl acetate (EVA)?

Ethylene-vinyl acetate (EVA) is a plastic made from ethylene copolymer and vinyl acetate. EVA is a highly elastic plastic that retains its strength even after being treated into a porous rubber-like substance.

EVA is also a material with excellent impact resistance, puncture resistance, and adhesive characteristics. It is favored over other comparable materials such as rubber and vinyl in many applications due to its high quality.

What are the features and characteristics of EVA foam plastic?

Because of its unique properties, EVA foam has become the preferred material in various applications, outperforming other comparable materials such as rubber and PVC.

Here are some of the most important benefits and features of EVA plastic:

  • EVA plastic is highly flexible and adaptable, and it can be either rigid or soft, making it appropriate for a wide range of uses.
  • Because of its high friction, it is ideal for object bearing or packing.
  • EVA foam is resistant to low temperatures and can keep its elasticity even at -70°C.
  • EVA plastic is tamper-resistant and crack-resistant due to its elasticity.
  • Because EVA plastic is resistant to ozone and UV radiation, it is ideal for outdoor applications.
  • EVA plastic is highly resistant to acids, alkalis, aliphatic hydrocarbons, and alcohols.

What happens if you heat EVA foam?

If you heat EVA foam, it will melt. The melting point of EVA varies from 90°C to 120°C. This fluctuates depending on the ratio of the copolymers. 

When heated to these temperatures, EVA foam will begin to release poisonous gases, necessitating the use of appropriate ventilation as well as the standard safety precautions for fires.

What are the uses of EVA Foam?

EVA foam is intended to survive extreme weather conditions and is resistant to a number of harsh and dangerous compounds such as fuel oil and chemicals. 

Because of these benefits, this plastic is widely utilized in various industries, including the health sector, shipping, footwear, electronics, and automotive industries.

According to Research Dive, the worldwide EVA plastic market is anticipated to reach USD 15,300 million between 2021 and 2028. 

The following are some of the essential EVA foam applications:

  • The medical business is the primary use for EVA plastic. This is due to EVA plastic’s chemical resistance and biocompatibility.
  • Because of its soft and light nature, EVA plastic is commonly utilized as a material for sandals and shoe soles.
  • EVA foam is great for foam packing and casing inserts or cushions.
  • EVA plastic is also frequently utilized in developing sports-related items, including yoga mats.

What is the industrial chain of EVA foam?

EVA foam can be made by welding, blow, injection molding, heat sealing, lining, or calendering.

EVA foam is made of EVA granules as raw material, with the addition of other additives after foaming injection molding. 

EVA granules are composed of ethylene and vinyl acetate Co polymers, and preparations, the English name for ethylene-vinyl acetate is EVA.

Granulation, mixing, and foaming are three steps in manufacturing EVA foaming materials. 

Granulation is the process of breaking down EVA resin into minute particles. At the same time, EVA foaming is the process of putting granules and other ingredients into a specific mold according to a formula. Different formulae might yield varying results.

EVA foam is then sold to industries, much like shoes. Scrap from the foaming process is also recycled.

Recycling EVA foam material not only helps the environment but also helps the foaming plant save money.

Is EVA Foam Safe for Kids?

According to the study, EVA foam is entirely safe for kids’ goods. Unlike plastics and other materials, they don’t employ toxic chemicals throughout the production process. 

No harm comes from purchasing things that include EVA foams. The usage of EVA foam is risk-free. However, it is advised that it be given by renowned EVA foam manufacturers that have been rigorously tested and shown to meet tight standards.

Nevertheless, despite the ACCC‘s recommendation that EVA foam goods be formamide-free, you may still wish to double-check.

Formamide was discovered in EVA foam a few years ago. The formamide used to soften the foam is thought to be carcinogenic and a developmental toxin. 

Formamide may be inhaled as well as absorbed via the skin. Children’s EVA foam mattresses were outlawed in Belgium in 2011.

Some firms will state that the EVA foam they use is free of formamide on their packaging or websites. Unfortunately, this isn’t always the case.

Simply email the firm in question and inquire if the item in question contains formamide if you are unsure whether or not it does.

Avoid purchasing products if the manufacturer refuses to answer your questions or does not do proper testing. Then tell them why you won’t be buying it so that the company would reconsider trying it in the future.

You can tell if a foam toy is composed of PVC or EVA just by smelling it. It is definitely PVC if it smells strongly of chemicals. Even if the label does not mention the product’s composition, you should probably avoid it!

Frequently Asked Questions (FAQs): Is EVA foam Flammable?

What is the durability of EVA Foam?

Unlike other foams, EVA foam is extremely durable and sturdy and can tolerate temperatures as low as minus 30 degrees Celsius. 

They are impervious to the elements and can tolerate many harsh and potentially harmful substances, including chemicals and fuel oils.

Is EVA foam biodegradable?

No. EVA foam is a non-biodegradable material, meaning the natural process cannot break it down. EVA is a petrochemical polymer with extremely strong atomic bonding used to make EVA foam. Nonetheless, it’s a better choice for the environment now that biodegradable EVA can be made.
