HPPA High Performance Polyamide as Lead-Free Resin for Potable Water Plumbing, Valves and Sanitary Fittings

Stricter lead-free regulations for drinking water systems push plumbing and sanitary manufacturers to source reliable engineering polymers. Certified HPPA (High Performance Polyamide) stands out as a cost-effective alternative to brass and standard PA66 for continuous cold & hot potable water contact.

Glass reinforced HPPA delivers low water absorption, outstanding creep resistance and stable dimensional performance in chlorinated hot water. It is widely adopted for valve housings, pipe connectors, faucet cartridges and manifolds.

Our water-contact HPPA grades, natural and black, can be processed on existing PA66 injection moulding machines. We support OEMs to accelerate certification, cut metal machining cost and produce durable sanitary water components.
