Polypropylene is an economical material that offers a combination of outstanding physical, mechanical, thermal, and electrical properties not found in any other thermoplastic. Noted for its excellent chemical resistance in corrosive environments, polypropylene provides excellent resistance to organic solvents, degreasing agents and electrolytic attack. It is light in weight, resistant to staining, and has a low moisture absorption rate.

Flame retardant grades of polypropylene have various UL ratings. They are more expensive and, because of the addition of the flame retardant fillers, they have lower physical properties and fabricating qualities. Flame retardant clad polypropylene has two outside skin sheets of flame retardant polypropylene that are coextruded onto a center core of polypropylene. This provides a composite material that is tough and with flame retardant exterior surfaces.

Emco’s CP7-D flame retardant polypropylene meet or exceed the most rigorous FMRC 4910 testing standards for most aspects of flame retardation, self-extinguishing characteristics and burn through. In addition, CP7-D also meets or exceeds test standards for low smoke generation and minimal toxic by-products. CP7-D is a filled PP sheet material, therefore, chemical compatibility should be verified for each application. Contact us for more information about this new material!
