Our materials


Polybutylene terephthalate (PBT) is one of the most common semi-crystalline construction plastics. Compared with PA 6.6, PBT has a lower moisture absorption and creep resistance up to 130 C, at the expense of lower impact resistance and harder processing.

PBT Properties

  • Semi-crystalline structure with a TG of 60 C and a melting temperature of 217 C
  • High rigidity, strength and hardness
  • Good thermal stability
  • Low moisture absorption and high dimensional stability
  • Excellent abrasion resistance
  • Chemical resistant to aliphatic hydrocarbons, oils and fats. Not resistant to alkalis, strong acids and hydrolysis
  • Glossy finish
  • Resistant to UV


Pocan® from our partner ENVALIOR offers a high heat resistance, strength and hardness, as well as excellent slip properties and high abrasion resistance, good resistance to chemicals, low susceptibility to stress cracking and low moisture absorption.
