Material Notes:

Type IV, gr. 2 PTFE. The unique properties of polytetrafluoroethylene (PTFE) makes it an indispensable material for modern industry. PTFE offers the following exceptional characteristics:Inert to a wide range of aggressive chemical agentsUltra-low friction coefficientContinuous service temperature range from cryogenic -330°F to 500°FExtremely resistant to embrittlement, aging or weatheringPTFE has rapidly become the material choice where low friction, high durability, excellent thermal resistance and chemical inertness characteristics are required.Data provided by Dyneon.
