 一, TPV, TPE in automotive strip/profile application

automotive system

◆车 use strip/profile 示例——TPV substitute/replace ternary 乙丙

◆车 use strip/profile 示例——TPV/PP共挤 substitute/replace ternary 乙丙

◆车 use strip/profile 示例——TPV substitute/replace ternary 乙丙

◆ composite/compounding extrusion strip/profile

according to requirements can soft hard 共挤, strip/profile flexible separation property can good, flexible and 开槽适应 property good, for 开槽公差 requirements wide 松, hard separation, 插入方便省工时. specific gravity light, easy processing, 米克数 relatively small. specifications more, product types full, can according to requirements made formed various color, meet/satisfy multiple demand, resistant property can excellent 越, property can good, wear resistant, solid resistant use.

◆ composite/compounding elastomer extrusion automotive strip/profile

utilizing types material extrusion molding, to assembly and use requirements, substitute/replace skeleton/framework belt/tape composite/compounding processing methods.

◆ automotive 玻璃导槽密封 strip/profile

surface 特征— fine 密麻面:

摩 scratch 次数（ add 载1kg）≥10万

features: ultra- low friction coefficient and high wear resistance, scratch more friction coefficient basic 不变

application: 玻璃导槽 coating substitute/replace 植绒

◆ inner / outer water 切密封 strip/profile

processing methods: TPV and PP共挤

main/primary property:

surface light slip good

long resistant outer property can excellent

excellent elastic property and resistant pressure shrink deformation property can good

◆ automotive elastomer strip/profile

TPV, TPE/PP材 material and friction coefficient small, wear resistance can good, can as is automotive 玻璃导槽, 车门玻璃 inner outer strip/profile and separation 辅助密封 strip/profile use material. if automotive strip/profile production enterprise and automotive machine can 够密切交流 combined as, let product in design upper more 精准, more 严谨, make strip/profile structure more add combined 理, to has 效密封, decrease small inner 噪音 目.

◆ composite/compounding extrusion 门窗密封 strip/profile

soft hard composite/compounding extrusion 门窗密封 strip/profile, decrease/reduce assembly 误差, improve/increase use property can, to design requirements. elastomer extrusion 门窗密封 strip/profile

utilizing elastomer mono extrusion more structure strip/profile, combined structure design, tool has good property can.

◆ elastomer extrusion use tube/pipe strip/profile

utilizing elastomer mono extrusion more structure strip/profile, combined structure design, tool has good property can.

◆ elastomer extrusion use tube/pipe strip/profile

◆ elastomer mono extrusion electrical appliances strip/profile

◆ mono material elastomer extrusion strip/profile

二, understanding: new material TPV, TPE

TPV, TPE by is industrial 第三次 revolutionary

1. features

◆ tool has 硫化橡胶 elastic property, also has thermoplastic property plastics processing properties

◆ environmental protection, energy saving, specific gravity light, cost low

2.TPE, TPV in automotive strip/profile application 概况

automotive strip/profile is anti 尘, key/critical parts, effect/influence automotive quality and appearance 美感. 随 轿车 market demand amount 提髙, add fast use thermoplastic property elastomer strip/profile development. automotive strip/profile requirements material tool has relatively 髙 回 elastic property, relatively small pressure shrink deformation, machine strong/high degree, relatively resistant aging property can and dimensional stability. 国 outer automotive more using/adopting ternary 乙丙橡胶（EPDM) production automotive use type strip/profile, 但EPDM need high temperature 硫化, processing process complex, price high. inner generally use thermoplastic property elastomer （TPE, TPV) production automotive strip/profile.

plastics versus and versus in melt blending process in, will 橡胶进行硫化, to 粒状硫化橡胶 versus micro versus stability in plastics versus in, this type of methods made raw materials material is 动态硫化 type thermoplastic property elastomer. 鉴于动态硫化 type blending TPE excellent comprehensive property can and application, 釆 use 动态硫化 methods made 备TPE already formed is inner outer polymer/macromolecule field/area research hot 点.

三, is selection TPV, TPE?

1. elastomer advantages

▶ excellent resistant property, resistant high low temperature property can, 同EPDM versus 当.

▶ excellent elastic property and resistant pressure shrink deformation property, more year rear still can maintain has 形状不变.

▶ tool has good resistant oxygen and resistant chemical property can.

▶ color property can good, can production various color sealant strip/profile.

▶不含卤素 and front and other heavy metal, combined green building materials requirements.

2.橡胶 low processing efficiency and can recycling property

—— to TPE进入 automotive provide more add vast use 空间

橡胶 processing process/workflow:

and versus ratio, elastomer processing versus for simple, front can 省 炼胶工段, rear can 省 硫 chemical industry 段, 且边角 material can recycling again utilizing.

molding dimensional stability good, process simple, extrusion, injection molding, production efficiency high, generate 污染, environmental protection belt/tape 困扰.
