PBT
Balances superior wear and moisture resistance in both wet and dry environments.
Approved by the FDA and USDA for use in food contact parts, PBT offers an ideal balance of wear resistance, moisture resistance, strength and toughness. It is also versatile enough to meet demanding electronic manufacturing requirements for dimensional stability, impact resistance and rigidity. PBT is easily machined and fabricated, and, when internally lubricated, reduces friction in high-speed wear applications.
