The information in this chart has been supplied by reputable sources and is to be used only as a guide in selecting equipment for appropriate chemical compatibility.
Which is better ethylene vinyl acetate vs polypropylene. Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va. General description eva is a transparent thermoplastic elastomer used a lot for extruded tubing and athletic shoes. Emblem in packaging technology 2012. Eva remains flexible at low temperatures and resists cracking.
Noun organic compound the common name for the organic chemical compound propene. Eva ethylene vinyl acetate. Ethylene vinyl acetate eva polypropylene pp homopolymer. 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.
Eva has limited application in injection molded components. Check the chemical compatibility of polypropylene with various chemicals solvents alcohols and other products. Metric units us customary units. Polypropylene chemical compatibility chart.
While the eva foam does not contain any rubber is is commonly referred to as expanded rubber or foam rubber. As the va content increases crystallinity decreases until at 50 the eva is. The material has low temperature toughness stress crack and uv radiation resistance. Eva foam is also waterproof.
Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. For each property being compared the top bar is eva and the bottom bar is pp homopolymer. Flexural modulus 8 000 13 000 psi. 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.
In this case are not shown. It s an extremely elastic material that can be processed like other thermoplastics. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. 0 91 to 1 2.
As nouns the difference between ethylene and vinyl is that ethylene is organic compound the common name for the organic chemical compound ethene the simplest alkene a colorless gaseous at room temperature and pressure hydrocarbon with the chemical formula c 2 h 4 while vinyl is chemistry uncountable the univalent radical ch 2 ch derived from ethylene. Flexible eva ethylene vinyl acetate is the copolymer of ethylene and vinyl acetate. Eva mats will have a glossy appearance and are resistant to uv radiation and cracking. Derived terms ethylene glycol ethylene oxide ethylene vinyl acetate polyethylene polyethylene terephthalate ester propylene.
Ethylene copolymer up two eva up one.
