industrial applications PBT plastics

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, Scientific Names polybutylene terephthalate (PBT), 英文 化 Scientific Names is Polybutylene Terephthalate, as is types new industrial production raw materials, PBT plastics time very 晚, is different its it industrial raw materials, it application scope from it by 发明出 that 天就一直 by use, can is types 备受瞩目 new general purpose industrial raw materials plastics.

PBT plastics has very good chemical stability property, machine strong/high degree, electrical insulation features and heat stabilized property. this several features by industrial production has utilizing to industrial production in, especially is in automotive industrial field/area, PBT 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.

due to its tool machine strong/high degree non good, therefore 经由PBT plastics processing made formed type automotive parts tool very good safety property, not only automotive use lifespan, more important is 保障 我们每 乘坐 automotive 人, is industrial production and safety provide 保障!

remove automotive industrial field/area, PBT plastics also by use in electronics electrical field/area upper, due to its good chemical stability property, heat stabilized property features, let 经由PBT plastics add manufacturing high electronics product has non good quality, but also more is important is PBT production high electronics product also tool very use lifespan, this is 我们消费者 provide relatively large in property!

总而言之, PBT plastics excellent features already by 我们运 use to industrial production and active in, versus in 不久 以 rear, PBT plastics 一定会 in 我们 各 field/area it light color, is full type it has 贡献

[材 material basic parameters ]

density1.30~1.38 g/cm³
melting point223~228°C
heat deflection temperature (HDT)60~210°C( reinforcement rear can 达210°C)
tensile strength50~60 MPa( reinforcement rear 120+MPa)
flexural modulus2400~2900 MPa
notched impact strength50~70 J/m
molding shrinkage1.5~2.5%
water absorption0.08~0.15%

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

electronics electrical

connectors, electrical appliances, 开关, electrical container outer housing/shell, ring framework

automotive industrial

点火 system parts, device housing/shell 体, 门锁, rear 视镜支架

use electrical appliances

electrical 熨斗底 sheet/plate, machine parts, machine housing/shell

industrial parts

泵体, 阀门, gears, bearings

light 纤通信

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
