CPC - Vycom PROTEC® Copolymer Polypropylene (CPP)

Protec CP is one of various types of "impact copolymers"—a rapidly growing segment of the thermoplastic sheet market. In contrast to homopolymer polypropylene (which involves the polymerization of a single monomer), impact copolymer synthesis consists of additional copolymerization of propylene and ethylene in a secondary reactor. By varying the secondary reactor conditions and the quantities of comonomer used, final properties can be tailored to meet a wide range of specific end-use application characteristics. Protec is formulated to provide high levels of impact resistance as well as corrosion resistance against a broad group of reagents, including organic solvents, degreasing agents and electrolytic solutions. Protec is a mid-density polypropylene, which retains its high tensile strength at elevated temperatures.FEATURES AND BENEFITS Impact Resistance- Protec CP has 10 times the impact strength of standard PP, even in cold temperatures. Corrosion Resistance- Protec CP has a broad chemical resistance over wide thermal range. Strength- Protec CP is lightweight, with an exceptionally high strength-to-weight ratio. Formability- Protec CP is well suited for thermoforming and deep drawing. Machinable- Protec CP is formulated to machine easier with less chipping and fraying. Weldable- Protec CP can be fabricated and welded with conventional plastic welding equipment. Stability- Protec CP is ideally suited to withstand cracking due to environmental stress. FDA- Protec CP is compliant with FDA regulations for food grade contact. NSF- The National Sanitation Foundation has approved natural Protec CP for food grade contact in food equipment.Information provided by Compression Polymers Corp - Vycom
