Shanghai Daoqin Plastics Co., Ltd.

 随 automotive light amount trend, automotive plastics 零部 parts use 越 越 more. 发达国家 will automotive use plastics amount as is amount automotive design and manufacturing water high low important 标志, Germany automotive use plastics 占 overall material 15%. in recent years automotive industry development speed, currently automotive year output/production volume ultra- 400万辆, 参照国 outer trend, automotive industry year use modified plastics will in 50 10,000 tons above, its in engineering plastics 占 very large separation ratio/proportion, used for automotive various parts.  

automotive plastics parts use engineering plastics has which?  
    一, nylon material （PA） 
     nylon main/primary used for automotive machine and machine 周边部 parts, main/primary product types is GFPA6, GFPA66, reinforcement flame retardant PA6 and other product.  
    1, in automotive machine 周边部 parts upper application: due to machine 周边部 parts main/primary is hot and 振动部 parts, its parts use material large more is glass fiber reinforced nylon. this is is nylon tool has relatively good comprehensive property can, use glass fiber (GF) modified rear nylon, main/primary property can to very large improve/increase, strong/high degree, products degree, dimensional stability and other. another, nylon product types more, relatively easy recycling ring utilizing, price versus for and other, this factors formed nylon formed is machine 周边部 parts selection material. gas tube/pipe is modified nylon material in automotive field/area in most is type application, 1990 year Germany automotive company, will glass fiber reinforced nylon is raw materials manufacturing gas tube/pipe application in 六汽缸发动 machine upper. rear USA use glass fiber reinforced PA66 manufacturing gas tube/pipe application in V6发动 machine upper, world large automotive company 纷纷跟进, modified nylon gas tube/pipe to application.  
    2, in automotive machine parts upper application: machine cover/cap, machine decoration cover/cap, 汽缸头 cover/cap and other parts generally use modified nylon as is material selection material, and metal versus ratio, 以汽缸头 cover/cap is 例, quality decrease light 50%, cost reduce 30%. remove machine parts outer, automotive other force parts can use reinforcement nylon, machine 油滤清 device, device, dispersion hot device and other.  
     poly nylon material in automotive field/area application:  
grade features application 材质 
SXX8523 glass fiber reinforced, heat stabilized automotive rear outer housing/shell PA6+15GF 
SXX8525 glass fiber reinforced, heat stabilized, weather resistant automotive dispersion hot 风扇PA6+25GF 
SXX8528 glass fiber (GF) and material reinforcement, heat stabilized, dimensions stability table/sheet sheet/plate PA6+30GF+30MD 
SXX6638矿 material reinforcement, heat stabilized, dimensions stability automotive 轮毂PA66+15MD 
SXX6813 heat resistant aging, electrical insulation high strength machine 械部 parts, outer housing/shell PA66+15GF 
SXX8633 heat stabilized, hardness high, can spray coating machine cover/cap PA66+20MD 
SXX8563 high strength, resistant salt, hydrolysis resistant, resistant force automotive machine dispersion hot system PA66+PA612+35GF 
SXX8566 glass fiber reinforced, heat stabilized, appearance good automotive gas tube/pipe, sheet/plate PA6+30%GF 

    二, polyester material （PBT） 
     in automotive manufacturing field/area, PBT广泛 used for production 保险杠, device parts, sheet/plate, sheet/plate, 火花塞端子 sheet/plate, system parts, table/sheet 盘, automotive device, accelerated device and combined device sheet/plate and other automotive parts. PBT and reinforcement PA, PC, POM in automotive manufacturing in competition separation 激烈, PA easy water, PC heat resistant property resistant property and PBT. in automotive applications tube/pipe 方面, due to PBT resistant water property excellent 于PA, will 会逐渐取代PA. in versus for wet degree relatively high, separation wet lower, due to wet easy 引起塑 property reduce, electrical appliances 节点处容 easy 引起腐蚀, can use modified PBT. in 80℃, 90% versus for wet degree lower, PBT still can positive use, and very good.
     poly 赛龙PBT材 material most main applications 于车灯 system:  
grade features application 材质 
SXX3104突出 heat resistant property, can electroplating property 车灯反 light parts PBT 
SXX4310 high heat resistant, rigid property good 车灯饰圈PBT+PET 

    三, polyoxymethylene (POM) 材 material （POM） 
     automotive industry is POM材 material most large in market. POM tool has light, hardness large, wear resistant, resistant creep, chemical resistant property and other advantages, non combined manufacturing automotive use automotive 泵, device parts, tube/pipe, force 阀, upper bearings, gears, 曲柄, 手, table/sheet sheet/plate, automotive rise drop machine plant/unit, electrical 开关, safety belt/tape and other, especially is slip block and other wear resistant parts is modified POM strong/high 项, this parts for metal abrasion consumption small, decrease/reduce lubricated use amount, reinforcement parts use lifespan.  
     poly company through reinforcement, toughened, wear resistant and other modified 手段, development series high property can polyoxymethylene (POM) product, widely used in automotive field/area:  
product type grade features application  
glass fiber reinforced POMSP520G20% glass fiber (GF) filling, high strength gears, bearings, 门 手, 喇叭格子, solid parts, control and other  
SP530G30% glass fiber (GF) filling, dimensional stability  
toughened POMSP500T high impact resistance  
wear resistant POMSP521WR20% glass fiber (GF) filling wear resistant  

    四, polycarbonate (PC) 材 material （PC） 
     modified PC due to tool has excellent heat resistant property, resistant impact property, rigid property and good processing flow property, in automotive upper main applications outer trim parts and inner trim parts, table/sheet sheet/plate 周围部 parts, anti sheet/plate, 车门 手, anionic sheet/plate, 托架, toward sleeve/set, decoration sheet/plate, system parts, 车灯零部 parts and other automotive parts.
