COPOLYMER POLYPROPYLENE
Protec® Copolymer Polypropylene 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.
Key Benefits
- Good impact resistance, even at zero temperature
- Excellent corrosion resistance over a wide temperature range
- Lightweight, with exceptionally high strength-to-weight ratio
- Excellent formability - suitable for deep drawing
- Highly machinable and weldable
- Ideally suited to withstand cracking due to environmental stress
- Excellent electrical properties
- Good abrasion resistance
