一, resin hot classification

（一） hot solid property plastics
hot solid property plastics material molding rear can again add hot soft heavy processing type plastics. its resin in processing front is property poly 体, processing in chemical crosslinked reaction make products internal formed is 三维网状 structure, tool has solvent, features. aldehyde resin, resin, ring oxygen resin and saturated and resin and other.

（二） thermoplastic property plastics
thermoplastic property plastics material molding rear again add hot can heavy new soft processing chemical formed 不变 一 type plastics. its resin in processing front rear is property structure, processing in 不发生 chemical 变化, tool has can 熔, can solvent features.
this category of resin very more, specific polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyamide (PA) type, polycarbonate (PC), polyoxymethylene (POM), polyester type, polyphenylene oxide (PPO), polymethyl methacrylate (PMMA), polyurethane ester, fluorine plastics type, polyphenylene sulfide (PPS), polysulfone (PSU) and polyimide (PI) and other.

二, resin application classification

（一） general purpose plastics
general purpose plastics material output/production volume large, application scope 广, molding processing good, cost low type resin, its output/production volume can resin large separation. specific product types polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), aldehyde resin, resin, saturated and polyester and ring oxygen resin and other. general purpose plastics main/primary used for packaging, construction, and day use and other field/area.

（二） engineering plastics
engineering plastics material force property can relatively good, dimensional stability high, in relatively high temperature degree lower can use type plastics, its use amount resin less separation. it tool has metal property can, can used for structure products machine 械, electronics, automotive and aviation and other field/area.

（三） generally plastics
generally plastics material use amount large, application scope 不广, property can generally type plastics. main/primary polymethyl methacrylate (PMMA), polyurethane ester, fluorine plastics type and chlorine polyether and other.

（四） specialty plastics
specialty plastics material tool has features can, price high, output/production volume less, application scope narrow type plastics. main/primary heat resistant plastics, retardant plastics and conductive plastics and other, specific product types has polyphenylene sulfide (PPS), polysulfone (PSU), polyimide (PI), poly amine and ethylene % ethylene alcohol copolymer and other.

三, resin structure classification

此 types classification methods is resin large separation upper can features classification, generally can separation formed lower type.

1. polyolefin type, large separation 子主, upper is type structure type resin and its copolymer, polyethylene (PE), polypropylene (PP), styrene, styrene / butadiene / acrylonitrile copolymer, butadiene, poly 甲基-1-戊烯, ethylene / ethylene alcohol copolymer and ethylene /乙 acid ethylene copolymer and other.

2. ethylene type, large separation 子主链 is type structure, 而侧链 is non 烷烃取代基 一 type resin and its copolymer, polyvinyl chloride (PVC), PTFE, poly fluorine ethylene and poly full fluorine ethylene and other.

3. polyamide (PA) type, large separation in has amine 基团 一 type resin, 包括PA6, PA66, PA610, PA46, PA1010, PA11, PA12 and PI and other.

4. polyester type, large separation in has ester structure type resin, types type very more, specific has PET, PBT, UP, PMMA, PC, POM, PAR, PSF, PES, PPO and PPS and other.

5. other types type also has fiber type, polyurethane ester type, aldehyde type, resin type and ring oxygen resin type and other.
