Product Description

GuangDong Engineering Plastics Industries (Group) Company, has studied and applied this material in many industries for many years. Due to very good processing properties, it can be filled with carbon fiber, Fiberglass and MoS2 etc. In order to improve lubrication performance and mechanical strength further.
1.PEEK-1000 This general purpose grade is unreinforced and offers the highest elongation and toughness of all PEEK grades. The newly available black PEEK 1000 is ideal for instrument components where aesthetics are important, as well as for seal components where ductility and inertness are important.
2.PEEK-HPV Carbon fiber reinforced with graphite and PTFE lubricants,our newest grade of PEEK offers the lowest coefficient of friction and the best machinability for all PEEK grades. Anexcellent combination of low friction,low wear,high LPV,low mating part wear and easy machining,make it ideal for aggressive service bearings.
3.PEEK-GF30 The addition of glass fibers significantly reduces the expansion rate and increases the flexural modulus of PEEK. This grade is ideal for structural applications that require improved strength, stiffness or stability,especially at temperatures above 300°F (150°C).
4. PEEK-CA30 The addition of carbon fibers enhances the compressive strength and stffness of PEEK, and dramatically lowers its expansion rate. It offers designers optimum wear resistance and load carrying capability in a PEEK-based product. This grade provides more thermal conductivity than unreinforced PEEK - increasing heat dissipation from bearing surfaces improving bearing life and capability.
