High Hardness plastic PEEK valve
PEEK（Polyetheretherketone）is a kind of heat-resistant, high performance thermoplastic special engineering plastics. It has good mechanical properties and chemical resistance, abrasion resistance, and hydrolysis resistance properties etc.; it has a light proportion and self-lubricating properties. Guangzhou 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.
Characteristics
1. Excellent dimensional stability
2. Low coefficient of linear thermal expansion
3. Good mechanical properties at elevated temperatures
4. Good resistant to hot water and steam
5. Bearing grade PEEK has excellent wear characteristics
6. UL 94 V-0 flammability rating (0.059" thickness)
7. Very low smoke and toxic gas emissions when exposed to flame.
8. Outstanding mechanical properties even at high temperatures
9.0ptimized balance of stiffness, tensile strength and impact strength.
10.Continuous operating temperature up to + 260°C and briefly even up to +300°C.
For CNC machining, the products will be sent for 3 days. And we support OEM and ODM.

Heat-resistance
PEEK has a higher glass transition temperature and melting point (334℃).
It is one of the reasons that it can be a reliable application in the requirement
of the heat. Its heat load variable-temperature can be 316℃, continuous use
temperature is 260℃.
PEEK Material features

High Quality PEEK Valve
PEEK Material-Model No:
PEEK-1000 (Natural)
This general purpose grade is unreinforced and ofere the highest elongation an
grades. The newly available black PEEK 1000 is ideal for instrument components where aesthetics are import
ant, as well as for seal components where ductility and inertness are important.
PEEK GF30 (30% Glass-Reinforced)
The adition of glass fibers significanty reduces the expansionrate and increases the flexural modulus of
PEEK. This grade is ldeal for structural aplications that require improved strength, siffnesss or sabilt.
espeially at temperatures above 300°F (150°C).
PEEK CA30 (30% Carbon Fiber Reinforced)
The adition of carbon fibers enhances the compressive strength and sifnes of PEEK. and dramatically
lowers its expansion rate. It ofers designers optimum wear resistance and load arrying capabilityina
PEEK- based product. Guangzhou Engineering Platics Industies (Group) Company has studied and aplied
thic material in many indutios for many yoare. Thie grado provide more thermal condutivity than unrin
forced PEEK -- increasing heat dssipation from bearing surfaces improving bearing life and ability.
PEEK HPV (Bearing Grade)
Carbon fber riforeed with grophite and PTFE lubricants, our newest grade of PEEK ofers the lowest cefi-
clent of rcto and the best machinablity tor all PEEK grades. An exellene combinaton of low rtcon lowwear, highLpv, low mating part wear and easy machining, make itideal for agressive service bearings.
