Pbt Rod (Hydex® 4101)


Pbt rod 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
