         in recent years, polypropylene (PP) copolymer injection molding field/area fast speed development polypropylene (PP) product structure adjustment. 2014 year polypropylene (PP) copolymer injection molding 消费300 more 10,000 tons, 2018 year data to 600 more 10,000 tons. year production enterprise 不断涉足 copolymer field/area, low copolymer field/area already saturated and, high field/area can production enterprise 依然不 more, inner for high copolymer degree comparison high, 本文一起探究 high copolymer application.

         high flow property copolymer polypropylene (PP) tool has high flow property, also tool has high impact strong/high degree and relatively good rigid property and tough property. main/primary used for injection molding large type thin products, 如直射 molding home appliances products, automotive parts, industrial parts, office use tool, furniture and other, large automotive, use products, food packaging and other large type thin manufacturing 业.

         currently inner high copolymer main/primary separation is direction: (1)洗衣 machine inner and outer housing/shell and other home appliances parts;(2) used as modified 基材, main/primary used for automotive field/area, separation used for home appliances;(3) injection molding manufacturing furniture, and toys and other product. generally modified industry comparison toward use high melt high impact resistance product, table/sheet grade 如燕山石化K9026, injection molding industry comparison toward use high in impact resistant property product.

        洗衣 machine is high flow property copolymer polypropylene (PP) use amount most in home appliances product, its in machine inner 桶, outer housing/shell, cover/cap sheet/plate, base/seat, water and other parts using/adopting copolymer polypropylene (PP) injection molding production, currently inner in machine sheet/plate and other parts has separation using/adopting ultra- high flow property copolymer PP(melt flow rate is 60g/10min left right).

         using/adopting high flow property PP substitute/replace ABS材 material tool has below/following advantages: (1)嵌段 copolymer PP tool has soft/flexible property, good, low, price low, easy recycling and other features. (2)嵌段 copolymer PP density low, from quality upper can 节省10%材 material. from price 差异, waste material recycling and other degree 出发, use PP材 material substitute/replace ABS can has reduce production cost.

        近几 year, machine use high flow property copolymer PP Domestic raw materials year development relatively fast, inner 包括燕山石化, in 沙天津, 扬子石化, Shanghai 石化, 广石化, 茂名石化均 can amount 产洗衣 machine raw materials, can meet/satisfy machine various parts use requirements.

         in automotive use material in, polypropylene (PP) is development speed degree most fast product types 之一, its in 保险杆 is most tool has table/sheet property polypropylene (PP) automotive parts, is polypropylene (PP) in automotive upper use amount relatively large made parts. according to automotive use requirements, 保险杆应 meanwhile tool resistant impact, heat resistant, resistant aging, low temperature resistance, rigid property good and other features. therefore, 保险杆 use polypropylene (PP) impact resistant copolymer 基材以 and copolymer modified specialized material is 主. currently inner copolymer polypropylene (PP) as is resin modified production specialized material already 越 越普遍.

         in recent years, automotive development trend for impact resistant copolymer polypropylene (PP) property can more high requirements, for automotive light amount 化, low cost development requirements material tool has high flow property, ensure material processing properties good, production cycle short; in addition, high crystallization degree can make material rigid property good, can decrease/reduce products thick degree, decrease light products quality, achieve light amount and low cost. therefore automotive field/area 而言, Raw Materials requirements versus for relatively high, inner large separation automotive use material need through modified 进而达 to demand, currently inner MFI 60 above polypropylene (PP) 基材数 amount relatively less, this separation in modified field/area has relatively high demand 空间.

         future, 随 国 inner large type thin injection molding products development, for polypropylene (PP) raw materials high flow property demand 会越 越 more, using/adopting high flow property demand 亦会越 越 more. using/adopting high flow property copolymer PP injection molding processing, reduce products production cost, improve/increase production efficiency processing advantages already formed is types development trend. high flow property copolymer PP development production and application areas expand large, formed is large polypropylene (PP) production enterprise and application enterprise and market has competition 积极面 for new 挑战.
