PBT plastics in what industry by 广泛 use
PBT plastics in what industry by use
PBT polybutylene terephthalate (PBT) | technology 文章 | Daoqin plastics raw materials
本文 will detailed introductionpolybutylene terephthalate (PBT) （PBT）material property can features, application areas and processing process, is material selection and product design provide 参考.
detailed introduction
我们 in to PBT plastics applications 时候, 不 不说, it in use upper separation 广泛, it is types product types, therefore in use 时候, 也就十 separation 广泛, in electronics electrical appliances industry in, it use 替即 广泛, in 几乎任何一样 electronics, 也都会 selection use it, ratio connectors, 开关, use electrical appliances, and other small electronics parts and other and other, has it 身影, therefore can in electronics to very good application, is it has 关本身 very good strong/high degree, again 者也就 is it in electronics reaction lower, 不会受 to loss 害.
当然 remove in electronics to is separation application outer, another it in automotive use very 广泛, in automotive has very large manufacturing amount, in automotive manufacturing 时候, this type of material use is important, but also is 广泛, ratio automotive external parts, 转角格珊, machine hot and other and other, is use this type of material, automotive internal very more parts use to this type of PBT plastics, ratio inner strip/profile, water device, system and other and other, this is automotive upper main/primary parts.
in is industrial 时代, therefore in use 时候, remove automotive and electronics 方面之 outer, another also has very more machine property expand 账国, ratio 如计算 machine outer housing/shell, water lamp covers, and other and other, very more industry outer housing/shell 往往也都会 selection this type of 樯, positive is is it in use 时候, 不但自身 strong/high degree can to, meanwhile can in types types chemical reaction lower can to very strong/high stability property, it in heat resistant upper 面, flame retardant 方面, meanwhile has property can advantages, PBT plastics property can advantages good, in application 方面也就 more add 广泛.
[材 material basic parameters ]
| density | 1.30~1.38 g/cm³ |
| melting point | 223~228°C |
| heat deflection temperature (HDT) | 60~210°C（ reinforcement rear can 达210°C） |
| tensile strength | 50~60 MPa（ reinforcement rear 120+MPa） |
| flexural modulus | 2400~2900 MPa |
| notched impact strength | 50~70 J/m |
| molding shrinkage | 1.5~2.5% |
| water absorption | 0.08~0.15% |
core advantages
- excellent chemical resistance: for large more has machine solvent agent, type and chemical product has good resistant can force
- good electrical insulation property: volume resistivity high, suitable for high pressure insulation application
- fast speed crystallization: cooling speed degree fast, molding cycle short, production efficiency high
- low water absorption: in wet ring in dimensions and property can small
- excellent creep resistance: in long negative lower deformation small
- reinforcement rear property can 突出: glass fiber reinforced PBT heat deflection temperature (HDT) can 达210°C above
application areas
connectors, electrical appliances, 开关, electrical container outer housing/shell, ring framework
点火 system parts, device housing/shell 体, 门锁, rear 视镜支架
electrical 熨斗底 sheet/plate, machine parts, machine housing/shell
泵体, 阀门, gears, bearings
light sleeve/set, light connectors
injection molding processing process
- drying 处理: 120°C drying 4-6 small 时, moisture content ≤0.03%
- material temperature degree: 230~270°C
- mold temperature degree: 40~80°C（ low mold temperature can shrink short molding cycle ）
- injection pressure: 60~100 MPa
- injection speed degree: fast speed （ utilizing PBT fast speed crystallization features ）
- precautions: PBT for hydrolysis 敏感, processing front must separation drying
