automotive field/area in ratio engineering plastics specific application

Date: 2019-11-20 09:49 Views: 2250 Source: Internet
engineering plastics used for automotive main/primary function is make automotive light amount 化, from to high speed 目. 发达国家 will automotive use plastics amount as is amount automotive design and manufacturing water high low important 标志, world upper automotive plastics mono use amount most large is Germany, plastics use amount overall material 15%.

in recent years automotive industry development speed, large engineering plastics property can features same, in automotive upper applications has heavy.

一, nylon

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 has very large improve/increase.

(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 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.

二, polyester

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 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.  

沙 ratio company PBT/PC alloy, product is Xenoy1731, in high grade in application most is 广泛; it heat resistant property good, resistant force cracking, tool has excellent wear resistant, chemical resistant property, low temperature impact strong/high degree high, easy processing and coating property good, main applications high 档轿车保险杠, sheet/plate, sheet/plate and 摩托车护 sheet/plate and other. its in ratio launch below/following tool has competition force PBT grade: 357,357U, 553, 553U, 1760,1760E, X4850, X4830, ENH4530, ENH4560, 310SE0, 420SE0 and other grade.

三, polyoxymethylene (POM)

automotive industry 饰POM most large in market. POM质 light, processing molding 简便, production cost low 廉, material property can and metal versus 近. modified POM wear resistant very low, rigid property very strong/high; 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.

manufacturing sleeve/set, gears, 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; therefore can substitute/replace copper, zinc and other metal production bearings, gears, and other. POM production automotive parts light, low, molding assembly 简便, therefore in automotive manufacturing obtain 越 越广泛 application.

四, polycarbonate (PC)

modified PC due to tool has high mechanical properties and good appearance, in automotive upper main/primary used for outer parts and inner parts, applications most is is PC/ABS alloy and PC/PBT alloy.

(1) automotive inner parts PC/ABS alloy is most combined used for automotive inner parts material. this is is PC/ABS alloy tool has excellent heat resistant property, resistant impact property and rigid property, good processing flow property. is manufacturing automotive table/sheet sheet/plate 理想材 material.  

PC/ABS alloy heat deflection temperature (HDT) is 110℃~135℃, full can meet/satisfy hot belt/tape 国家炎 hot in automotive in outer 停放 受 hot requirements. PC/ABS alloy has good coating property and for cover/cap film property, therefore use PC/ABS alloy made formed table/sheet sheet/plate 无需进行 surface 预处理, can spray coating soft 质面漆 or coating PVC film.

PC/ABS alloy also use manufacturing automotive 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 and other automotive parts.

(2) automotive outer parts PC/PBT alloy and PC/PET alloy tool has PC high heat resistant property and high impact property, also tool has PBT and PET chemical resistant product property, wear resistance and molding processing property, therefore is manufacturing automotive outer parts 理想材 material.

PC/PBT automotive 保险杠 can resistant -30℃ below/following low temperature impact, 保险杠 fracture is tough property fracture 而无碎 sheet/slice generate. elastomer toughened PC/PBT alloy and PC/PET alloy more combined made as automotive sheet/plate, automotive 侧面护 sheet/plate, sheet/plate, automotive frame and other. high heat resistant type PC/PBT alloy and PC/PET alloy injection molding outer parts can use coating 漆. PC/PET alloy can made as automotive gas and sleeve/set.

PC/ABS alloy can made as automotive outer parts, automotive 车轮罩, light outer housing/shell, lamp covers and other. PC/ABS tool has good molding property, can processing automotive large type parts, automotive sheet/plate. its in ratio launch below/following tool has competition force PC/ABS grade: XCY620S, CY8630, C4220, LG9000, MC1300, XCY620,MC8002 and other grade.

五, polyphenylene oxide (PPO)

modified PPO in automotive upper main/primary used as for heat resistant property, flame retardant property, electrical property can, impact property can, dimensional stability, machine strong/high degree requirements relatively high parts. 如PPO/PS alloy suitable for wet, has negative and for electrical insulation requirements high, dimensional stability good combined, combined manufacturing automotive 轮罩, front 灯玻璃嵌槽, housing/shell and other parts, combined manufacturing box/case, filament box/case, 断路开关 outer housing/shell and other automotive electrical parts.

PPO/PA alloy due to tool has excellent force property can, dimensional stability, oil resistant property, electrical insulation property, impact resistant property. can used for made as automotive external parts, large type sheet/plate, 缓冲垫, rear retardant sheet/plate and other. for 玻璃化转变 temperature degree requirements relatively high machine 罩时PPO/PA alloy in the future application direction.

PPO/PBT alloy heat deflection temperature (HDT) high, for water separation degree small, is manufacturing automotive outer sheet/plate 理想材 material. its in ratio launch below/following tool has competition force PPO grade: GTX973,GTX830,IGN320,GTX914, N190X, GFN1F and other grade.

automotive industry development direction is high 档次, micro type 化, light and more 元化, 以塑代钢 in automotive application in research 也变 十 separation active 跃. currently inner automotive use plastics 平均占总材 material 7%, Germany this ratio/proportion in 15%; need add large R&D as, to parts structure design, plastics selection and industry development.
