丁苯 transparent impact resistant resin, also 称K-Resin（K- resin ）.

丁苯 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.

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 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 high speed 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 injection molding 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 理员 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.

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

key features

①象玻璃一样清澈, transparent and light 亮, meanwhile also tool has high tough property and impact resistant property.
② can and polystyrene (PS) （GPPS, HIPS） mixed combined. K resin can need balanced PS product rigid property and tough property, make cost more optimization.
③生理 safety property: combined and USA food and product tube/pipe has food packaging 规定, but also tool has material versus property （ISO 10993,  USP V1-50）.
④ has multiple recycling can selection: production waste material can recycling, as again manufacturing, for formed product quality 无任何 effect/influence, meanwhile can used as recycled polystyrene (PS) impact resistant modifier.

processing properties

①吸 wet less, processing front drying.
② processing temperature degree relatively wide, generally in 160--260℃ between, flow property good, easy processing.
③不 crystallization, shrinkage rate low, easy deformation, warpage and other.
④二次 processing: A printing property can: more grade k胶 can printing, for relatively difficult printing can using/adopting electrical electrical 处理, and other 离子处理 or 火焰处理 rear again printing. B bonding: can using/adopting solvent agent bonding ,例如:醋 acid ester, chlorine 甲烷;也 can use ultra- 声波 welding.

main applications

① high property ratio and transparent property: application K resin packaging tool has excellent dimensional stability

K resin food packaging （如杯子, pallet and food box/case and other ） not only appearance but also solid resistant use.
K resin not only transparent, but also tool very high impact resistant strong/high degree, can meet/satisfy food industrial requirements. this type of material excellent features for/regarding requirements high degree dimensional stability and hot molding food packaging （如饮 material 杯, 沙拉盘, 熟食盘 and belt/tape cover/cap and film 铰链 午餐 box/case and other ）都 is important.
transparent sheet/slice thermoforming product already widely used in medical devices, product and property electronics product packaging upper. utilizing K resin and polystyrene (PS) （GPPS） between excellent mixed combined property manufacturing transparent packaging sheet/slice 材, can make thermoforming product more and more tool cost 效益.

② thin tough property strong/high: application K resin flexible packaging

K resin film has long food （如 new 鲜蔬菜, 即食沙拉 and other ） 保存期, and make food more 诱人.
remove transparent outer, in this application in especially important requirements also has resistant 穿刺, can printing, high shrinkage rate and water separation and gas 体（ oxygen gas or oxidation carbon ） high property. K resin tool has can production high quality film excellent heat stabilized features, this type of film can is mono film or extrusion more composite/compounding film.
另一 application is manufacturing used for shrinkage packaging and label high flexibility property film and used for packaging and 捆扎 缠绕 film.

③象玻璃一样清澈 transparent, tool resistant fracture property: application K resin injection molding parts

K resin is toys, medical devices, ring use product, product and office supplies and other many application areas in various product 理想材 material.
K resin injection molding parts tool has 玻璃一样 transparent degree, 引人注目 surface gloss, good impact resistant property and excellent flow property. this features separation combined made as precision design, complex and light color 泽（ can is transparent or transparent ） product.
因 tool has high property, K resin use manufacturing 链接, and 钉装位也 milli issues.
