Nine Material Series, 40+ Grades
From neat PEEK to carbon-fiber-reinforced composites, PI and PTFE — a complete engineered material system under one roof.
PEEK (Neat)
Unfilled PEEK with up to 260°C continuous service, UL94 V-0 flammability and high strength and toughness.
PEEK · unfilled gradePEEK CF30
30% carbon-fiber reinforced PEEK for high stiffness, low creep and superior wear resistance.
CF30 · carbon fiberPEEK GF30
30% glass-fiber reinforced PEEK with high rigidity and excellent dimensional stability.
GF30 · glass fiberPEEK + PTFE
Self-lubricating PEEK-PTFE blend for low friction, reduced wear and dry-running sliding parts.
PEEK+PTFE · self-lubricatingPI (Polyimide)
~300°C continuous service, radiation-resistant with excellent high-temperature strength retention.
PI · extreme temperaturePTFE
Ultra-low friction (COF ~0.04) with nearly universal chemical resistance for seals and gaskets.
PTFE · chemical resistantFive Core Manufacturing Processes
