Pbt Rods (Hydex® 4101)


Pbt rods Hydex® 4101 is a polyester that is less brittle, more chip resistant, and easier to machine than PET. Pbt has the strength & wear resistance of general purpose nylon, and a higher continuous use temperature (240° F) It is FDA/NSF/3A Compliant.

Hydex 4101 and Hydex 4101L (internally lubricated) represent a family of stock shape plastics with elevated performance over PET-P, Acetal and Nylon. Hydex 4101 is a PBT Polyester with an outstanding set of properties that include; wear resistance, chemical resistance and toughness. Hydex 4101L (Lubricated) is an enhanced version with improved wear, PV range and lubricity over Hydex 4101. In direct comparison to other commonly used plastics, Hydex 4101 and Hydex 4101L have:

Improved Wear and Chemical Resistance Versus Acetal

  • Hydex 4101 and 4101L are compatible with chemicals having a pH range of 2.0 - 9.0, Acetal's range is 4.0 to 9.0
  • Hydex 4101 and 4101L can with stand repeated "CIP" chemical washdown without affecting material performance. Acetal degrades upon repeated contact with aqueous chlorine solutions.
  • Hydex 4101L has 30% higher limiting PV than Delrin AF
  • Hydex 4101L has about two times better wear factor than Acetal
  • Hydex 4101L is approved for direct food contact, Delrin AF is not

Superior Dimensional Stability Over Nylon

  • Hydex 4101 and 4101L have moisture absorption of 0.07%
  • Nylon has moisture absorption 15 times greater than Hydex, and can exhibit significant dimensional changes in use

Best Wear and Lubricity When Compared to PET-P

  • Hydex 4101 and 4101L have 20% greater impact strength than PET-P
  • Hydex 4101L has about 50% better wear factor than PET-P
  • Hydex 4101L has more than twice the LPV performance than PET-P
  • Hydex 4101L has 50% lower coefficient of friction than PET-P
