EVA is one of the materials popularly known as expanded rubber or foam rubber. EVA foam is used as padding in equipment for various sports such as ski boots, bicycle saddles, hockey pads, boxing and mixed-martial-arts gloves and helmets, wakeboard boots, waterski boots, fishing rods and fishing-reel handles.
What is ethylene copolymer used for?
Ethylene copolymers and terpolymers are widely used in manufacturing hot-melt adhesives due to their mechanical cohesion and adhesive properties. They are highly flexible products, compatible with many other polymers and additives.
What is EVA film used for?
It can be used for the replacement of PVB (Polyvinyl butyral) materials used in the automotive and construction industry. In the production of security laminated glass it can contribute to safety, insulation, sound insulation, anti-ultraviolet and other properties.
How do you use ethylene-vinyl acetate?
EVA can be used as a substitute for cork in many applications. EVA copolymers are adhesives used in packaging, textile, bookbinding for bonding plastic films, metal surfaces, coated paper and as redispersible powders in plasters and cement renders.
Is ethylene-vinyl acetate copolymer plastic?
Soft, flexible plastic with low-temperature toughness and stress-crack resistance. Flexible EVA (ethylene vinyl acetate) is the copolymer of ethylene and vinyl acetate. It's an extremely elastic material that can be processed like other thermoplastics.
Is ethylene-vinyl acetate copolymer safe?
Therefore, the CEF Panel concluded that the substance ethylene-vinyl acetate copolymer wax does not raise a safety concern for the consumer if it is used as additive up to 2 % in polyolefins and the migration of low molecular weight oligomeric fraction below 1 000 Da does not exceed 5 mg/kg food.Feb 6, 2014
How toxic is ethylene-vinyl acetate?
Polyethylene vinyl acetate has recently become a popular alternative to polyvinyl chloride because it does not contain chlorine. As of 2014, EVA has not been found to be carcinogenic by the NTP, ACGIH, IARC or OSHA, and has no known adverse effect on human health.
Is vinyl acetate polymer toxic?
Exposure to high levels (around 1,000 ppm) of vinyl acetate in air for a couple of weeks caused irritation of the eyes, nose, throat, and lungs of laboratory animals. Vinyl acetate at levels around 200 ppm caused irritation to the respiratory tract and nose when it was breathed by rats and mice for up to 2 years.
Is EVA safe to use?
EVA is considered to be a safe alternative to PVC, as it doesn't require plasticizers like phthlates, and it's BPA free. However, a few years ago it was found that EVA foam contained formamide. Formamide is used to make the foam soft, but it's considered to be carcinogenic and a developmental toxin.
What is ethylene-vinyl acetate used for?
Ethylene–vinyl acetate copolymers (EVA), containing from 25 to 50% vinyl acetate, are used in adhesives. The vinyl acetate contributes tack, solubility, improved adhesion to polar surfaces and low temperature flexibility.
How is ethylene-vinyl acetate made?
Ethylene-vinyl acetate copolymer (EVA), for instance, is produced by the copolymerization of ethylene and vinyl acetate under pressure, using free-radical catalysts. Many different grades are manufactured, with the vinyl acetate content varying from 5 to 50 percent by weight.
