Stainless Steel Filled PTFE has enhanced mechanical properties by the use of a 50% by weight (or 15% by volume) stainless steel powder filling.
The material is extremely hard wearing, has excellent strength and stability under extreme loads and elevated temperatures whilst still retaining the low coefficient of friction of conventional PTFE. It is an extremely versatile product and can be used on Steam and Thermal Fluid applications.
It is also an extremely good seat material for use in V-Ball type Flow Control Ball Valve applications due to its high resistance to wear.
- Extremely hard wearing
- Excellent strength and stability under extreme loads and elevated temperatures
- Lowers creep, cold flow and wear
- Increased thermal and electrical conductivity
- Very heavy
