Examples of TPE s include:Santoprene, Nitrile (TPE) and s are manufactured using a plastic injection molding process where the resin, or diaphragm material, is melted and injected into a mold to produce thediaphragm.

3 36 AM Page 12 THERMOPLASTIC COMPOUNDS (TPE)Thermoplastic elastomeric (TPE) diaphragms are manufactured using an injection molding process. The process allows the part to be molded in the shape andconfiguration required of the diaphragm to provide excellent performance and life. The TPE resins used to manufacture the diaphragms exhibit excellentdimensional and tensile characteristics eliminating the fabric reinforcement. The following TPE s are used in ARO diaphragm (TS)These materials are manufactured from natural rubber and man made additives to enhance resistance to various fluids. Diaphragms are manufactured using acompression molding process. A nylon fabric mesh is molded in the diaphragm to add strength to the The most chemically inert man made compound known. New diaphragm design and material processing have significantly improved flex life equivalent to orexceeding rubber compounds.
