Shanghai Daoqin Plastics Co., Ltd.

         polypropylene (PP) (PP) is types 源广, price low general purpose property plastics resin, has non 常广泛 applications. due to property large (especially is low temperature property), crystallization degree relatively high, separation property small, PP and other polymer/macromolecule (如 plastics, 橡胶) and machine filler blending property and bonding force very 差, made its in field/area application.

        20世纪90 year 代初, USA 提出先进 solid versus grafting modified method, already development related product, 如伊士曼 company production chlorine modified PP(MCPP) resin, in market 每吨售价 high 达50 more 10,000 yuan. modified PP(MPP) and MCPP as is specialty PP specialized material, large large expand PP application scope, tool has large 经济效益. using/adopting solid versus grafting method for and other 规PP进行 modified to MPP, rear for MPP进行 chlorine can obtain MCPP solid powder resin. chlorine modified rear resin force strong/high, modulus improve/increase, easy and other resin blending; but also due to modified make PP crystallization to bad, property increase, from can solvent certain solvent agent, made different concentrated degree MCPP solvent liquid.

        MPP applications main/primary has 四 方面. is improve/increase engineering plastics resistant impact property can. use MPP as compatibilizer, made PP and other plastics blending material impact strong/high degree improve/increase 2～3倍, can used as impact resistant housing/shell material;二 is exfer plastics company development Dexpro alloy, is polyamide (PA) and PP in compatibilizer in lower alloy, already product 化;三 is used as hot plastics powder coating material, used for metal surface, to anti and resistant chemical product function. Japan Nozagl-GIZ grade product is PP and nylon alloy material, tool has relatively high chemical resistant product and oil resistant property can, especially is tool has resistant chlorine property can is improve/increase PP filler bonding property. MPP can improve/increase filler and PP versus property, improvement composite/compounding material property can, improve/increase material overall heat stabilized property and local resistant hot can force;四 is MPP也应 used for 自由基 active property waste material solid 化. in addition, MPP also can used for improve/increase PP fiber can color property and plastics products can decoration, manufacturing can packaging materials and other.

         from market upper 看, year inner PP demand amount in 350 more 10,000 tons, its in PP specialized material in 100 10,000 tons above. grafting method modified PP demand amount 以10 10,000 tons / year grade 计, main/primary used for: and other polymer material nylon, polycarbonate (PC), and other blending, made new type polymer/macromolecule material; add filler machine powder 体, glass fiber, fiber and other, made high strength PP;进一步 processing product, used for powder coating material, liquid coating material and other. currently and other 规PP solid versus grafting modified methods 尚 空白, has type product market, 需空缺 main/primary Imported, Germany 赫司特 company in 我国推广 modified PP product is 15000～18000元/ year.

        MCPP applications main/primary has: is used for made plastics products use and plastics surface decoration coating material force promote agent, especially is 轿车保险杠, cover/cap, electrical machine machine housing/shell and other use and industrial use plastics device tool coating 装;二 is a large amount of used as plastics surface printing ink resin;三 is used as anti coating material resin, used for 钢屠, aluminum and other material heavy anti field/area.

        随 plastics products a large amount of use, for plastics surface decoration 越 越关注. is due to plastics products surface can low, in difficult 以直接 coating and coating 装 附 force relatively and other issues. usually plastics surface in coating front, need surface treatment, main/primary methods has 2 types. is using/adopting 火焰, electrical electrical, gas and other and other surface treatment, this category of technology difficulty/challenge is need formed uniform surface, also can degree, 否则会导致 surface polymer fracture, from effect/influence material property can. is using/adopting surface 底漆进行 surface treatment, its in chlorine polyolefin (CPO) is relatively is 理想 底漆 resin, can used for made improve/increase force or used as force promote additives. USA 伊士曼 company already industrial FastmanCP164-1 solvent agent type product (solid content 25% 二甲苯 solvent liquid) and CP310W and CP347W water property product. 据悉, 伊士曼 company 25% CPO solvent liquid product inner market high 达125元/kg. most also has patent 报道 含 has CPO resin acrylic polyurethane ester 漆, can used as one-time property 面漆; ring oxygen /MCPP coating material is 1 types resistant acid alkali property can very good anti coating material.

        MCPP resin use plastics parts surface coating demand amount is 500吨/ year above, metal surface anti coating material field/area demand amount ultra- 20 10,000 tons, in printing ink 方面, currently market demand amount in 500吨/ year above. currently 广州珠江 electrical using/adopting solid versus chlorine method production modified chlorine 化PP, production can force to 30000吨/ year, product separation 畅销, is 35000元/吨 left right. USA 伊士曼 company production MCPP solid material material, inner high 达500000元/吨, 50% MCPP solvent liquid 售价则达270000元/吨 left right. PP modified product as is PP function product, can large large wide PP application areas, has market and application outlook/prospects, value large force development.
