Hydex® PBT Rods

PBT 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

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

Superior Dimensional Stability Over Nylon

• Hydex® 4101 has moisture absorption of 0.07%
• Nylon absorbs moisture 15 times better than Hydex, so Hydex could develop significant dimensional changes in use

Best Wear and Lubricity When Compared to PET-P

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