EVA plastics raw materials

Date: 2024-06-05 21:42 Views: 5376 Source: Internet

EVA(ethylene-vinyl acetate copolymer) plastics raw materials, 英文简称: EVA, is ethylene-vinyl acetate copolymer (EVA). technology 说明书编码:1314 CAS No.: 24937-78-8 separation 子式: (C2H4)x.(C4H6O2)y.

EVA材 material is types day active in comparison Common type in material, use it made formed formed product tool has soft/flexible property good, anti 震, anti slip, resistant pressure property strong/high, 如我们 Common EVA拖鞋, 棉鞋, EVA手 machine sleeve/set, EVAipad保护 sleeve/set and other.

polymerization methods use high pressure polymerization ( plastics use ), solvent liquid polymerization (PVC processing additives ), emulsion polymerization ( bonding agent ), polymerization. acid ethylene (VA) content high 于30% using/adopting emulsion polymerization, acid ethylene content low use high pressure polymerization.

EVA features

stability property: tool has good chemical stability property, resistant aging, resistant oxygen property.

resistant water property:密闭泡孔 structure, water, anti 潮, resistant water property can good.

corrosion resistant property: resistant water, 油脂, acid, alkali and other chemical product 腐蚀, antimicrobial, 无毒, 无味, 无污染.

processing property:无接头, easy 于进行 hot pressure, 剪裁, coating 胶, combined and other processing.

anti 震动:回 elastic property and resistant force high, tough property high, tool has good anti 震, property can.

保 temperature property: thermal insulation, temperature anti and low temperature property can excellent, can resistant and 曝晒.

隔音 property:密闭泡孔, 隔音效果 good

EVA( ethylene-vinyl acetate copolymer (EVA) ) application areas:

1, acid ethylene content in 5%~10% EVA product is elastic property film and other;

2, acid ethylene content in 20~28% EVA, main/primary used for hot bonding agent and coating products;

3, acid ethylene content in 5%~45%, main/primary product is film (包括农 use film ) and sheet/slice 材, injection molding, products, foaming products, hot bonding agent and other.

(1) foaming footwear materials. footwear materials is 我国EVA resin most main/primary application areas. in footwear materials use EVA resin in, acid ethylene content generally in 15%~22%. due to EVA resin blending foaming products tool has soft/flexible, elastic property good, chemical resistant and other property can, therefore by widely used in in high 档旅游鞋, 登山鞋, 拖鞋, shoe sole and inner material in. another, this type of material also used for sheet/plate, 体操垫 and 密封材 field/area.

(2) film. EVA film main/primary applications is production function property film. function property film tool has relatively high weather resistant, anti and temperature property can, due to polyethylene (PE) tool has property, make add amount anti agent, its anti property can can 维持2 month left right.

而添 add amount EVA resin made formed film, not only tool has relatively high light transmittance, but also anti property can has relatively large improve/increase, generally can ultra- 4 month. another, EVA also can used for production packaging film, medical grade film, lamination film, film and other.

(3) electrical cable. 随 计算 machine and engineering development, for machine safety 考虑, 人们越 越 more use flame retardant cable and silicon crosslinked cable. due to EVA resin tool has good filler property and can crosslinked property, therefore in flame retardant cable, semi 导体屏蔽 cable and method silicon crosslinked cable in use relatively more.

another, EVA resin also by used for made as 一 特殊 cable sleeve/set. in electrical cable in use EVA resin, acid ethylene content generally in 12%~24%.

(4) toys. EVA resin in toys in has relatively more application, 如童车轮, base/seat and other.

(5) hot melt adhesive. 以EVA resin is main/primary formed separation hot melt adhesive, due to solvent agent, 不污染 ring safety property relatively high, non combined 于自动化 流 water production, therefore by widely used in 书籍无线装订, furniture 封边, automotive and use electrical appliances assembly, made 鞋, carpet coating and metal anti coating upper.
