Poly(ethylene-co-vinyl acetate) (EVA) is a copolymer of ethylene and vinyl acetate (VA). It is important to determine the VA content of EVA, since the properties of EVA depend highly on the VA content. EVA copolymers have been used in a wide range of applications appropriate for the different VA con...

EVA는 무엇인가? | Poly(ethylene-co-vinyl acetate) (EVA)는 에틸렌과 비닐아세테이트(vinyl acetate, VA)의 공중합체이다. EVA는 에틸렌 영역에 의해 결정성을, VA에 의해 비결정성 영역을 가지는 반결정성 고분자이다. | |
에틸렌과 비닐아세테이트의 공중합체는 무엇인가? | Poly(ethylene-co-vinyl acetate) (EVA)는 에틸렌과 비닐아세테이트(vinyl acetate, VA)의 공중합체이다. EVA는 에틸렌 영역에 의해 결정성을, VA에 의해 비결정성 영역을 가지는 반결정성 고분자이다. | |
PE를 EVA로 보강할 경우 어떤 장점이 생기는가? | PE는 오존저항성, 내화학적 특성과 물적 특성이 좋지만 응력 균열 저항성이 좋지 않다. EVA로 보강할 경우 응력 균열 저항성 뿐만 아니라 충격강도, 노화저항성, 저온유연성, 기체투과성, 수분흡수성, 전기저항성이 좋아진다. 30 일반적으로 PE는 LDPE와 HDPE로 나누어진다. |
