中石化北海炼化聚丙烯装置于2014年9月3日成功试产出超高熔体流动速率纤维级聚丙烯专用树脂与纺丝专用料Y45S,熔体流动速率高达5.888 g/min。目前,北海炼化聚丙烯装置是国内使用固体降解剂稳定生产出超高熔融指数聚丙烯纤维产品的少数装置之一。高熔体流动速率纤维级聚丙烯专用树脂与纺丝专用料,是在现有通用聚丙烯树脂V30G基础上,通过加入新型助剂——固体过氧化物,调整聚丙烯分子链
On September 3, 2014, Sinopec North Sea Refining & Polypropylene Unit successfully produced Y45S, an ultra-high melt flow rate fiber-grade polypropylene resin and spinning special material, with a melt flow rate of up to 5.888 g / min. At present, Beihai Refining and Polypropylene Plant is one of the few devices that can stably produce ultra-high melt index polypropylene fiber products using solid degrading agent in China. High melt flow rate fiber-grade polypropylene special resin and spinning special material, is based on the existing general-purpose polypropylene resin V30G, by adding a new type of additives - solid peroxide, adjust the polypropylene molecular chain
