PP toughening agent and POE brief introduction
POE is types use metallocene catalytic agent production ethylene --a烯烃 copolymer, polymer has low crystallization degree, density very low, molecular weight distribution narrow, catalytic temperature degree low and other 特征. this make its for machine filling material has good property, tool has good elastic property and flexibility property and other, its hardness very low, in various industry has application.
一, PP modified.
POE has good elastic property and flexibility property, its hardness very low, resistant property 极佳, therefore POE elastomer used for PP toughened, improve/increase PP normal temperature and low temperature lower impact strong/high degree, modified toughened rear PP application has, automotive 保险杠, automotive sheet/plate, home appliances outer housing/shell, office tool, electrical bottle and 摩托车 plastics parts and other.
二, and EVA并 use foaming.
POE flexibility property and elastic need ratio EVA high very more, very more lower, POE and EVA并 use foaming has 令人满意 效果, foaming rear product weight more light, pressure shrink elastic more good, 触感良 good, uniform fine 腻, strong/high degree high and other advantages. is pressure foaming also is pelletizing rear injection foaming, POE都 already a large amount of by use in 如沙滩鞋, 拖鞋, 运动鞋 in 底, 鼠标垫, base/seat 垫, 保丽龙材 material, temperature material, sheet/slice 材, 箱包衬里 and other foaming product upper.
三, PA and other engineering plastics toughened, compatibilizer.
POE non property although make its and 如PA, PET and other engineering plastics versus property good, 但POE through oxidation material 引发, can 顺利且 has and MAH, GMA, AA and other mono 体发生 grafting reaction, to grafting material use toughened PA and other engineering plastics, meanwhile can as compatibilizer used for plastics alloy in.
四, improvement PP/PE回 material property can.
PP or 者PE回 material due to again processing rear degradation or crosslinked, make PP/PE回 material or powder rear material 都会变 very 脆, method a large amount of add or use, add POE blending pelletizing, or 者直接 injection molding, make PP/PE回 material property can large is 改观, used for plastics pallet, plastics turnover box, plastics tool 箱, plastics office parts, 沙滩椅 and other.
五, extrusion tube/pipe industry.
in soft tube/pipe industry, especially is extrusion 缠绕波纹 tube/pipe, EVA and POE mixed combined use to product more flexibility, resistant property more 佳, product more light, resistant ring force more 佳. add in extrusion tube/pipe inner 层, make soft tube/pipe tool has resistant property 封口, hot temperature degree low hot strong/high degree more high!广泛 应 used for device soft tube/pipe, machine soft tube/pipe, water tube/pipe.
六, 无纺布 or CPP film
Vistmaxx elastomer add can increase 无纺布 黏 property, elastic property, flexibility property and other property can. add in CPP film in, can large improvement its tough property, resistant strong/high degree, resistant strong/high degree and other, improvement its hot strong/high degree.
七, hot melt adhesive
POE can 代替EVA production high hot melt adhesive, product can to 无异味, low density, high flow coating property, lubricating property good and other. can and EVA并 use!
八, flame retardant cable material
POE can a large amount of filling AL(OH)3 or Mg(OH)2 , its hardness and strong/high degree rate low, 代替EVA or and EVA并 production use flame retardant cable material already formed large 势 趋. POE也 can use oxidation material or 者辐照进行 has crosslinked.
