PBT plastics large 独特 advantages
PBT plastics large advantages
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
PBT plastics is engineering plastics types, in full in use PBT plastics, due to it tool very good property can, make PBT plastics formed is plastics industry in 佼佼者, 人们像众星捧 month PBT plastics in high 位. has 人曾经说, in is belongs to PBT plastics 时代, this 句话应该说一点也不 separation.
in 我们 生 active in, 几乎处处都 can to use PBT plastics made formed product, ratio in 我们各 type automotive industry in, in 我们家庭 application electrical appliances upper 面都离不开他, 当然, has good more for/regarding PBT plastics can can also 不太明白, also 不知道他 to tool has what features, let this more is 他倾倒呢, that let toward 你说说 it 独特之处吧.
PBT plastics is upper general purpose plastics, it tool very good insulation property can, resistant solvent agent property can, and resistant aging property can and other and other, positive due to it has very more features, make in very more industry in, formed can less color, 科研部门精心研 made PBT plastics not only can let production reduce cost, meanwhile can let 我们 出行 more safety, has it 保障, is very 放心. let 我们 生 active fast 捷一.
in, large understanding PBT plastics excellent features, for PBT plastics can force large add 赞赏吧. 随 时代 development, PBT plastics will more new 换代, more good development, will in 各行各业发挥 light 芒, 我们坚信PBT plastics as is plastics industry in force 军, outlook/prospects is non vast, is very has force, meanwhile 也希望 has 识之士, add this 团队, 于PBT plastics front 进.
[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
