Polybutylene Terephthalate (PBT) Compounds – Virgin, Hybrid & Recycled Grades

PBT (Polybutylene Terephthalate) is the engineering polyester of choice where dimensional precision, electrical insulation and moisture resistance matter most. Unlike polyamides, PBT absorbs very little water, so parts hold their dimensions and electrical properties in humid environments.

Features

  • Low water absorption – stable properties in humid conditions
  • Superior dimensional stability for precision components
  • Superior electrical properties – ideal for connectors and switchgear
  • Superior chemical and abrasion resistance
  • Superior wear properties for moving and contact parts
  • Good color stability over service life

Typical Applications

Electrical connectors, switchgear and relay housings, automotive electrical and lighting components, appliance parts requiring precision and electrical insulation, and industrial components exposed to moisture.
