Eva stands for ethylene vinyl acetate and it is the co polymer of ethylene and vinyl acetate.
Advantages of ethylene vinyl acetate.
Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va.
It is produced under high temperature and high pressure.
Also it imparts plastic like properties that enable wax to compete effectively with high quality polymeric coatings.
It is the basis of many hot melt adhesives when blended with a petroleum wax and a resin tackifier.
It offers good gloss low temperature toughness good chemical resistance high friction coefficient and resistance to uv radiation.
Eva ethylene vinyl acetate this copolymer resin can be used in adhesives sealants and coatings.
Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial.
As the va content increases crystallinity decreases until at 50 the eva is.
Emblem in packaging technology 2012.
The vinyl acetate content determines the degree of elasticity.
The va comonomer interferes with chain packing reducing crystallinity and thus lowering t m and improving transparency when compared with ldpe.
Some of these derivatives include polyvinyl acetate polymers and ethylene vinyl acetate copolymers.
Whether you ride jet skis raft in white water race speed boats water ski or enjoy kayaking eva foam will easily become your best friend.
Vinyl acetate also known as vinyl acetate monomer or vam has a chemical formula of c4h4o2.
Eva foam is the acronym for the closed cell ethylene vinyl acetate copolymer foam used as an effective substitute for a variety of materials used in production.
Eva has a slight characteristic odour of vinegar acetic acid and competes with rubber products as well as with certain polymers in many electrical applications.
The interaction between vinyl acetate and ethylene monomers provides vae dispersions with an outstanding range of technical performance benefits along with environmental advantages at an attractive cost in use ratio.
Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene.
The food and drug administration fda has stated that ethylene vinyl acetate is safe when used in food production packaging or transportation and it s not an especially dangerous material.
Ethylene vinyl acetate eva is a copolymer of ethylene and vinyl acetate.
It is a suitable substitute for natural rubber vinyl neoprene polyurethane and pvc foams wood composites felts fiberglass and mineral wool.
It also has good transparency and gloss and resistance at low temperature to stress cracking and uv radiation.
This chemical is primarily used as a raw material in the production of other industrial chemicals.
For example flexibility adhesion and water resistance can be adjusted as needed by varying the monomer composition.
It is an extremely elastic and transparent material.
