Manufactory Price Wholesale Engineering Special Plastic Peek Valve Valves
PEEK 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. Due to very good processing properties, it can be
filled with carbon fiber and MoS2 etc. to improve lubrication
performance and mechanical strength further.
Product Characteristics
1. Corrossion resistance. PEEK is semi-crystalline ,does not
dissolve in common solvent,so it has very very good corrossion
resistance to kinds of organic and inorganic chemical reagent.
2. Rub resistance.It can be applied for many severe environment.
3. Fire resistance.UL 94 V-0 flammability rating (0.057"
thickness).
4. High temperature resiatance.Continuous operating temperature up
to + 260°C and briefly even up to +300°C.
5. Good mechanical properties at elevated temperatures.
6. Hydrolysis resistance.Soaked in temperature of 250ºC (482°F)
steam or high pressure water,it still works for thousands of hours
with good characteristics.
7. Low coefficient of linear thermal expansion
8. Very low smoke and toxic gas emissions when exposed to flame
9. Optimized balance of stiffness, tensile strength and impact
strength.
Strength of PEEK valve plate
According to PEEK excellent charteristics, compare to metal or
other materials, PEEK valve plates have following strengths:
A. Long service life
B. Better sealing performance
C. Better flowing characteristics
D. Better impact resistance to liquid or solid particle
E. Low noise when machin works
F. Excellent slef-lubrication, can used for oil or non-oil working
environment
