According to the different raw materials used in its polymerization, it can be divided into five categories: ①Aliphatic resin and alicyclic resins, usually made from C5 fractions, also known as C5 resins; ②Aromatic resin, usually made from C9 fraction, also known as C9 resin; ③Aromatic hydrocarbon-aliphatic hydrocarbon copolymer resin, also known as C5/C9 resin; ④ Dicyclopentadiene resin, made fro...
Ethylene-vinyacetate copolymer (ethylenevinyacetatecopolymer), also known as EVA resin, is made of ethylene and vinyl acetate. EVA resin is an odorless, tasteless, non-toxic, white or light-yellow powder or granular Low melting point polymer, relative density 0.12~0.95, refractive index 1.480~1.510, brittle temperature less than -71 ℃. Because of its low crystallinity, high elasticity, rubber-like...
