Stainless steel filled PTFE sheet is a premium fluoropolymer known for its superior mechanical strength, enhanced wear resistance, and better thermal conductivity compared to standard PTFE grades. This material offers excellent chemical resistance (excluding certain alkali metals, chlorine trifluoride, and elemental fluorine) and effectively dissipates static electricity. It operates across a wide temperature range, holds a UL94 V-0 flammability classification, and is approved for use with both wet and dry food products.
Among PTFE composites, the stainless steel filled variant stands out for its improved load-bearing capacity and shares a similar kinetic friction coefficient with bronze and glass filled types. Its enhanced mechanical properties and compliance with FDA and EC food safety standards make it a preferred material in the food processing sector. The inclusion of 316L stainless steel filler increases hardness and facilitates machining.
Henry Gallacher offers in-house CNC machining to convert stainless steel filled PTFE sheets into finished components such as bushings, gaskets, and sliding plates. This material is widely used in the chemical and food processing industries, where high compressive strength and anti-static properties are essential.
