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
very more plastics in 我们 生 active in is has very more application, can let in this to very more important development, let 我们 生 active more add 方便. for/regarding PBT plastics 讲, this type of material production is has many important 意义.
this type of PBT plastics tool has very more important property 质. important 一点便 is can in very more conditions lower maintain stability. therefore this type of material in production electronics product is types separation important material. 我们都知道, this electronics product is in 我们 生 active in by use 一 材 material, formed 我们 现代 生 active, this type of plastics development is this electronics product development, has very more important development 意义.
而另一方面 讲, PBT plastics in industrial production upper is has very more application. this type of material is can 够帮助我们进行 very more related development types material, in 我们 生 active in is can by application.
positive is is this 方面, 我们生 active in very more material product is this material development. this material in 我们生 active upper 面 位也 is in this upper can 凸显 出. this plastics 推动 我们生 active in very more material development, and, 也推动 very more development.
总而言之, PBT plastics is types separation good material, in 我们 生 active in is has very more related application, positive is is this 样, production is has separation important 意义. can in 我们 生 active in has separation important in 意义.
[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
