What Is PBT Resin?
PBT (Polybutylene Terephthalate) is a semi-crystalline thermoplastic engineering polymer renowned for its exceptional blend of properties and processing attributes.
Benefits of PBT Plastics
As PBT suppliers, our PBT plastics have a myriad of advantages such as good dimensional stability, high heat resistance, chemical resistance, etc. Moreover, PBT resins exhibit superior tensile, flexural, and dielectric strengths compared to numerous thermosetting materials. PBT is often used as an insulator in the electrical and electronics industries to ensure reliable insulation in various applications. Contact Prochase PBT resin supplier to learn more!
- Outstanding Chemical Resistance to diluted acids, alcohols, aromatic hydrocarbons, ketones, solvents, oils, and greases…
- Extremely High Electrical Resistance & High Dielectric Strength:It helps protect electrical and electronic components.
- Low Molding Temperatures than many engineering plastics since it crystallizes rapidly.
- Withstand Long-term Heat Exposure due to its high HDT and high temperature index.
- Good Durability under thermal stress and harsh chemical environments.
- Good Creep Resistance, Dimensional Stability, and Low Water Absorption.
PBT resins are usually applied in wiper covers, outer handles, mirror housings, cowl vents, cooling fans, fuel system components, connectors, bumpers, micro-motor housings, fuse boxes, ignition system parts, couplers, power tool casings, IC sockets, plug connectors, circuit breakers, terminal boards, keyboards, dryer nozzles, toothbrush bristles, lamp base, iron handles, etc.
