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 represents 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. In direct comparison to other commonly used plastics, Hydex 4101 has:
Improved Wear and Chemical Resistance Versus Acetal
Superior Dimensional Stability Over Nylon
Best Wear and Lubricity When Compared to PET-P
