PPS (Polyphenylene Sulfide) film is an impact-modified, unreinforced extrusion grade.   PPS offers high tensile elongation, unusual flexibility and ductility.  Film also has high temperature resistance, impact strength and flexibility.  This new grade retains many of the traditional benefits of Fortron® PPS including excellent adhesion to nylons and polyolefins, high chemical resistance and very low fuel permeation.  For example:  .005" film of Fortron® PPS SKX-382 has a gasoline (CE10) permeability rate of 0.121 g mm/m2/day, which is far less than that of nylon, polyketone and other resins often used with gasoline and other fuels. 

Application and General Information

Impact-resistant PPS Fortron®  SKX-382 impact-modified polyphenylene sulfide exhibits unusual ductility and flexibility. It has a high melt strength for extrusion or blowmolding as a monolayer or as part of multilayer structures. It adheres well to nylons and polyolefins. Its tensile elongation at break is 25%, while its flexural modulus is 2140 MPa and its notched Izod impact strength is 40 kJ/m^2.

PPS is generally used in applications where high temperature and chemical resistance are required. A continuous use temperature of 428 degrees F and short term properties at 500 degrees F allow PPS to be used in automotive, electronic (solderability) and many OEM applications. 

PPS materials are inherently V-O due to an oxygen index of 47 or higher.

PPS offers the broadest resistance to chemicals of any advanced engineering plastic. They have no known solvents below 392°F (200°C) and are inert to steam, strong bases, fuels and acids. Minimal moisture absorption and a very low coefficient of linear thermal expansion, combined with stress-relieving manufacturing, make PPS ideally suited for precise tolerance machined components.

As an unfilled material, PPS is easily machined to close tolerances. It is ideal for structural applications in corrosive environments or as a lower temperature replacement for PEEK. Fortron® PPS SKX-382 film color is Off White
