Shanghai Daoqin Plastics Co., Ltd.

  POE features is quality separation high (>20%), density relatively low, versus for molecular weight distribution narrow, has crystallization degree. this type of structure make its tool has property and applications,既 can used as 橡胶, also can used as thermoplastic property elastomer, also can used as plastics impact modifier and toughening agent, in multiple plastics toughened modified in to relatively good application. it not only can toughened modified and its versus property polyolefin plastics, also can modified and its nylon, polyester and other engineering plastics, in multiple toughening agent in 脱颖而出,并 for toughening agent formed has force competition. and EPDM, EPM, SBS, EVA and other material versus ratio, its features is:商 product 化POE呈自由 flow pellets 状态, ratio EPDM处理 or and its it polymer mixed combined more easy, more uniform; processing property and force property can balanced property excellent, although 门尼黏 degree low (in 5~35 between),但 force property can can and high 门尼黏 degree material versus 媲美,消 remove generally elastomer 门尼黏 degree low, processing properties good force property can 差 弊端; can utilizing oxidation material, silicon and method crosslinked, crosslinked rear hot aging and resistant outer light, weather resistance and other excellent 于EPDM; POE脆化 temperature degree low (-76e), same content POE, EPDM, EPR for PP toughened is POE>EPDM>EPR; using/adopting generally as is plastics impact resistant modifier, in improve/increase impact strong/high degree meanwhile reduce product strong/high degree,而POE in toughened meanwhile still can maintain relatively high strong/high degree and flow property;¾ hot pressure shrink deformation ratio EPDM small;未 crosslinked POE density ratio EVA and SBS low 10%~20%; its optical property can and resistant property excellent 于EVA; this type of metallocene polyolefin elastomer substitute/replace EPDM配 mixed production PP基TPO, impact resistant property can more excellent, will in automotive 保险杠, table/sheet sheet/plate surface and other more application market, formed is EPDM modified PP type TPO strong/high has force competition product types.
