PBT (Polybutylene Terephthalate)

Hydex 4101 and 4101L PBT rods and sheets have elevated performance over PET-P, Acetal and Nylon.

PBT Compared to Acetal

• Improved wear and chemical resistance vs. Acetal
• Hydex 4101 and 4101L are compatible with chemicals having a pH range of 2.0 - 9.0; Acetal's range is 4.0 - 9.0
• Hydex 4101 and 4101L can withstand repeated "CIP" chemical wash down 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 2 times better wear factor than Acetal
• Hydex 4101L is approved for direct food contact: Delrin AF is not

PBT Compared to Nylon

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

PBT Compared to PET-P

• Hydex 4101 has 20% greater impact strength than PET-P
• Hydex 4101L has 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 about 50% lower coefficient of friction than PET-P

Hydex® 4101 is a PBT Polyester with an outstanding set of properties including: wear resistance, chemical resistance and toughness.

Hydex® 4101L (Lubricated) is an enhanced version with improved wear, PV range and lubricity over Hydex® 4101.
