Description

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 leading PBT suppliers, our PBT plastics offer a myriad of advantages such as good dimensional stability, high heat resistance, and chemical resistance. Moreover, PBT resins exhibit superior tensile, flexural, and dielectric strengths compared to numerous thermosetting materials. PBT granules are often used as insulators in the electrical and electronics industries to ensure reliable insulation in various applications.

Features
  • Outstanding Chemical Resistance: Resistant to diluted acids, alcohols, aromatic hydrocarbons, ketones, solvents, oils, and greases.
  • Extremely High Electrical Resistance & High Dielectric Strength: Protects electrical and electronic components.
  • Low Molding Temperatures: Crystallizes rapidly compared to many engineering plastics.
  • Withstands Long-term Heat Exposure: Thanks to its high HDT (Heat Deflection Temperature) and high temperature index.
  • Good Durability: Performs well under thermal stress and harsh chemical environments.
  • Excellent Creep Resistance, Dimensional Stability, and Low Water Absorption.
Applications

Polybutylene terephthalate (PBT) resins are versatile and used in a wide range of applications, including:

  • Automotive Components: Wiper covers, outer handles, mirror housings, cowl vents, cooling fans, fuel system components, connectors, and bumpers.
  • Electrical and Electronics: Micro-motor housings, fuse boxes, ignition system parts, couplers, power tool casings, IC sockets, plug connectors, circuit breakers, terminal boards, and keyboards.
  • Consumer Goods: Dryer nozzles, toothbrush bristles, lamp bases, iron handles.

Polybutylene terephthalate production focuses on creating high-quality resins that meet the demands of these varied applications. Explore the many polybutylene terephthalate uses and discover how our PBT granules can enhance your products.
