(1) and ethylene-vinyl acetate * * * polymer (also known as ethylene-vinyl acetate * * * polymer) are polymerized from ethylene (e) and vinyl acetate (va) * *, which is called ethylene vinyl acetate in English and abbreviated as EVA or E/VAC.
(2) EVA is an ethylene-vinyl acetate * * * polymer (also called ethylene-vinyl acetate * * * polymer) polymerized from ethylene (E) and vinyl acetate (VA).
(The content of vinyl acetate (VA) in EVA is 5%-40%. Compared with polyethylene (PE), EVA reduces its high crystallinity and improves its toughness, impact resistance, filler compatibility and heat sealing performance.
Second, what is the use of EVA:
(1), which is widely used in industries such as shock-proof and anti-skid, sealing and heat preservation of electronic appliances, metal can lining of various packaging boxes, etc.
(2) Products are widely used in: instruments, gifts, printing, packaging, machinery, tablet computers, mobile phones, digital cameras, air conditioners, water dispensers, computers, electronic appliances, communications, military products, speakers, lighting, toys and other industries. Stationery supplies, tourism supplies, children's toys, preschool children's handmade DIY products, EVA packaging products, etc. (EVA
(3) Materials are widely used in shoes, bags, packaging, sports equipment, hats, toys, ready-made clothes, bedding, decorative materials, sofa materials, car mattresses, ceiling, communication equipment, household appliances, electronics industry, computers, hardware tools, medical instruments, instruments, furniture, toys, handicrafts, travel goods and stationery.
