Stainless steel filled PTFE sheet is a high performing fluoropolymer that provides enhanced mechanical properties, resistance to wear and improved thermal conductivity in comparison to standard grades of PTFE.
What is PTFE steel?
Polytetrafluoroethylene or PTFE is a particularly versatile ivory-white and opaque plastic fluoropolymer; it is made by the free-radical polymerisation of many tetrafluoroethene molecules, and is suitable for a wide range of applications in industries as diverse as aerospace, the food and drink industry.
What is the difference between PFOA and PTFE?
PFOA stands for perfluorooctanoic acid while PTFE stands for polytetrafluoroethylene. The key difference between PFOA and PTFE is that PFOA contains a carboxylic acid group as the functional group in addition to carbon and fluorine atoms, whereas PTFE is a polymer containing only carbon and fluorine atoms.
What is the material composition of stainless steel?
Composition of Stainless Steel Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements.
What is the HRC of 304 stainless steel?

How is PTFE made?
Polytetrafluoroethylene, also known as Teflon®, is made with four ingredients — fluorspar, hydrofluoric acid, chloroform, and water, which are combined in a chemical reaction chamber heated to between 1094-1652°F (590-900°C). These ingredients are combined in a process known as pyrolysis.
What are the mechanical properties of 304 stainless steel?
1 Datasheet-2, Mechanical Properties. The tables below list SS 304 material mechanical properties including yield strength, tensile strength, elongation and hardness, etc. 2 Physical Properties 3 Magnetic Properties. Type 304 stainless steel is not magnetic, but may be slightly magnetic after cold working.
What are the physical properties of PTFE?
Properties. It maintains high strength, toughness and self-lubrication at low temperatures down to 5 K (−268.15 °C; −450.67 °F), and good flexibility at temperatures above 194 K (−79 °C; −110 °F). PTFE gains its properties from the aggregate effect of carbon-fluorine bonds, as do all fluorocarbons.
What is PTFE fluoropolymer resin?
PTFE fluoropolymer resins are part of the family of fluorine-based products that also includes Teflon™FEP and Teflon™PFA and Tefzel™fluoropolymer resins. These materials can be used to make a variety of articles having a combination of mechanical, electrical, chemical, temperature, and friction resisting properties
What is the typical forging temperature of 304 stainless steel?
Type 304 stainless steel typical forging temperature is 925-1260 ℃ (1700-2300 ℉). AISI SAE ASTM 304 stainless steel can’t be hardened by heat treatment but can be hardened by cold working. When the weldment is not suitable for full annealing, the residual stress of SS304 grade stainless steel can be moderately reduced below 450 °C.
