What are the characteristics of PTFE sealing rings？
PTFE sealing ring is no stranger in the hydraulic fluid industry, PTFE sealing ring is a thermosetting material without a volume point, can be produced into engineering plastics by sintering method.
1.PTFE sealing ring has excellent dielectric resistance and is compatible with almost all chemicals
2.PTFE sealing ring temperature range is large, can withstand minus 196 degrees to zero before 260 degrees, and can work near the peak temperature for a long time
3 PTFE sealing ring friction coefficient is very low self-lubrication, in most of the industrial products,PTFE perfect conductivity resistance, fire resistance and not spontaneous combustion and the ability to spread the flame of the sealing materials.
4, pure PTFE its strength and hardness is relatively low, and it has the characteristics of easy creep and easy cold flow, as a seal, we generally fill carbon fiber, bronze powder or glass fiber to modify, so as to improve its mechanical properties to meet the needs of various working conditions.
