Overview
High-performance polymer seals are vital in demanding environments where pressure, temperature, and chemical exposure challenge traditional elastomers. Materials like PTFE, PEEK, and UHMWPE offer exceptional wear resistance, low friction, and long-term dimensional stability. These properties make them ideal for sealing solutions in valves, pumps, and dynamic assemblies across critical industries.
PTFE
Exceptional chemical resistance, wide temperature tolerance, and low friction; ideal for aggressive media and dynamic sealing.
PEEK
High strength and excellent wear resistance at elevated temperatures; used where durability and precision are essential.
PVDF
Combines chemical resistance with mechanical strength; used in applications involving acids, solvents, and high purity requirements.
PPS
High thermal stability and creep resistance; ideal for compact sealing applications requiring structural integrity.
UHMWPE
Extremely low friction and abrasion resistance; used in reciprocating seals and high-wear environments.
Polyamide
Good mechanical strength and wear resistance; used in valve seats and low-load bearing seals.
Acetal
Offers dimensional stability, low moisture absorption, and ease of machining; ideal for static and semi-dynamic sealing elements.
Back-up rings
Prevent extrusion of primary seals under pressure; polymers like PTFE and PEEK add strength and chemical resistance.
Thrust washers
Reduce axial wear and resist deformation; UHMWPE and Acetal are preferred for their toughness and low friction.
Ball-valve seats
Ensure bubble-tight sealing and low torque operation; PTFE and Polyamide allow for chemical resistance and resilience.
Butterfly valve seats
Provide tight shut-off and corrosion resistance; PVDF and PTFE perform well in chemically aggressive flows.
Piston-ring seals
Withstand dynamic loads and offer low wear; PEEK and PTFE enable high-temperature, high-speed sealing.
Rotary shaft seals
Maintain sealing in rotating assemblies; materials like PTFE and PPS reduce friction and wear.
Spring-energised seals
Combine polymer lips with metal springs for responsive sealing; PTFE and PEEK ensure flexibility and chemical inertness.
Lip seals
Offer low-friction sealing in dynamic setups; UHMWPE and PTFE reduce heat generation and wear.
Tapered valves & components
Precision-machined for flow control and sealing; Acetal and PPS maintain shape under stress.
Chevron / V-packing seals
Multi-lip stack seals for high-pressure use; PTFE and PEEK resist creep and ensure sealing integrity.
