丁苯 transparent impact resistant resin （K- resin ）

丁苯 transparent impact resistant resin, also 称K-Resin（K- resin ）. transparent impact resistant resin is styrene, butadiene is mono 体, 以烷基锂 is agent, using/adopting anionic solvent liquid polymerization technology combined formed types copolymer, its key features is has high transparency property and good impact resistant property, density small, color force strong/high, processing properties excellent, property, it used for manufacturing, electrical appliances table/sheet and its it material （如GPPS, SAN, SMA, PP, HIPS and other ）掺 mixed modified and other field/area, can using/adopting series processing technology for K- resin development application.

一, K resin brief introduction:

styrene butadiene copolymer （SBC） is transparent resin. K- resin copolymer is Phillips chemical industry 科研人员 combined formed and in year 代早期投放 market that rear, 独特 兼 has light 耀, transparent property and resistant impact strong/high degree K- resin copolymer to 越 越 more development, market to stability expand large.

can using/adopting series processing technology for K- resin development application. pure K- resin or mixed general purpose plastics property polystyrene (PS) K- resin can through extrusion molding made formed sheet/slice 材, and in equipment upper high output/production volume hot molding. remove can production outer, from upper 看, K- resin can is 人 接受, can used for made formed easy transparent material 杯, cover/cap and other packaging materials. 同样, K- resin as is injection molding processing properties good, ring time combined 理, design active. injection molding transparent long combined box/case utilizing K- resin features 一 例子. K- resin through narrow combined 页铰链 film 腔注入 rear, still tool has separation tough property ensure lifespan. for/regarding in blow molding 说, K- resin can in large separation equipment upper processing, 而不必 for equipment 做昂贵 改动, 例如不 need using/adopting mold, different or add drying can molding crystallization transparent bottle. K- resin can using/adopting in blow molding made formed various dimensions and product, from small bottle, medical grade plant/unit, to high 身 陈列 show/display 美工. 不必改动注 bad blow molding equipment, can made formed high resistant strong/high degree 玻璃样 transparent bottle. another, K- resin can manufacturing has rigid property, high gloss transparent label packaging use film. if can 避免极端 processing and powder recycling utilizing, polymer can more recycling utilizing, in property can upper and processing can upper has micro small 变化.

and its it transparent polymer comparison, K- resin copolymer features is density low, from 经济角 degree upper more has force. K resin rate ratio non styrene type transparent resin high 20~30%, and combined USA food product tube/pipe FDA 21 CFR 177 1640 strip/profile * and Europe EEC指引90/128/EEC之 therefore strip/profile * 规定, used as food packaging. K- resin in medical grade market in has very large ratio/proportion, combined as USP V1-50材 material use, can using/adopting ring oxygen gas or outer 射线消毒.

currently world upper transparent impact resistant resin （ Phillips product is K resin ） 总 output/production volume is 150kt, 1999 year world demand amount is 240kt.
