Hytrel杜邦TPE 4069--TPE has softtouch, weather resistance, fatigue resistance and temperatureresistance. It has superior processing performance and does notneed vulcanization. It can be recycled to reduce the cost. It canbe used for secondary injection molding, coated and bonded with PP,PE, PC, PS, ABS and other matrix materials, or formedseparately.
TPE development history:
With the rapid development ofdomestic economy, more and more TPE international manufacturersbegan to set up factories to produce TPE in China.
In 2012, elasto, a subsidiary ofSweden's HEXPOL group, is expected to build its first TPEproduction line in Foshan in the second half of 2012.
In 2010, American PolyOne ac business of the former American GLS, including GLS's factory inSuzhou.
The rapid development of automobileindustry drives the rapid development of thermoplastic elastomermarket.
Thermoplastic elastomer (TPE) hasthe physical and mechanical properties of vulcanized rubber and theprocessability of thermoplastic. Because there is no need forthermal vulcanization, the product production can be completed byusing general plastic processing e This feature shortensthe production process of rubber industry by 1 / 4, saves energyconsumption by 25% ~ 40%, and improves efficiency by 10 ~ 20 times.It can be called another material and process technology revolutionin rubber industry.
TPE--热固性弹性体材料,通称TPE或TPR,是一种新型的高分子材料复合材料,在其中丁二烯热固性弹性体材料,又称之为丁二烯系嵌段聚合物,是当前全球生产量比较大,与硫化橡胶特性较类似的一种TPE商品。SBC相比于别的热固性弹性体材料,具备抗压强度高、绵软、形变小等特性,并具备硫化橡胶延展性,适用做为热融生产加工的黏着剂和橡胶密封件,在机械制造业、塑料改质、沥清改质、防水材料、液封原材料、电缆线、电缆线、汽车零部件、医疗机械构件、电器产品、办公室自动化技术和黏着剂等领域有着普遍的运用。SBC关键有4种种类,各自为丁二烯-丁二烯-丁二烯嵌段聚合物(SBS)、丁二烯-异戊二烯-丁二烯嵌段聚合物(SIS)、丁二烯-丁二烯-丁烯-丁二烯嵌段聚合物(SEBS)及丁二烯-丁二烯-pe-丁二烯型嵌段聚合物(SEPS),在其中SBS关键适用于塑料和沥清改质剂;SEBS关键用以黏着剂、医用品、车辆、家用电器和自动化技术办公用品;SIS以及加氢裂化商品SEPS关键用以热融型黏着剂与沥清改质,不一样国家和地区其适用范围各各有不同。
