Description
It is the standard choice for seals, valve seats, thrust washers, and piston rings where dimensional stability under load is critical.
Hi-Tech Polymers machines all filled PTFE grades in-house — from raw rod, sheet, or tube stock directly to finished components as per customer drawings. Our machining capability is central to our value proposition: customers receive a material-and-machining solution from a single supplier with full traceability.
