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

Superior Dimensional Stability Over Nylon

Best Wear and Lubricity When Compared to PET-P
