Stainless Steel-Filled PTFE

Stainless steel is the other metallic PTFE filler choice when extreme wear resistance to high temperatures is required. Stainless steel is added in in high amounts, usually 50% in weight, which is equivalent to 15% in volume, to improve the thermal conductivity and reduce the deformation under load when Stainless steel-filled PTFE materials are subjected to load at extreme temperatures.

Stainless steel-filled PTFE materials have very good abrasion resistance and compressive strength. Stainless steel-filled PTFE materials are typically used for seats and seals that require high heat and steam applications.

Moreover, stainless steel-filled PTFE materials are highly machinable and comply with FDA and EC regulations, so they are the preferred choice in the food processing industry.
