Polybutylene Terephthalate (PBT)

Polybutylene Terephthalate (PBT)

Polybutylene Terephalate, is a polyester. It is known by the trade names Velox® and Ultadur®. The Snow white natural color makes this FDA/USDA compliant material a good choice in food applications. Other properties include:

  • Outstanding chemical resistance – especially to chlorine
  • Low moisture resistance
  • Good dimensional stabilty
  • Excellent wear resistance

Polyethylene Terephthalate (PET)

Common trade names are Ertalyte® and Ensitep®. It has no center line porosity, very good chemical resistance, and low
moisture absorbtion. PET makes a great alternative to Nylon or Delrin in certain applications. Some other key properties are:

  • Excellent hardness and stiffness.
  • High flexural modulus & mechanical strength.
  • Low coefficient of friction, excellent wear resistance.
  • Natural white color is compliant with USDA/FDA/NSF
  • Continuous service temperature of 230°
