Polypropylene copolymer (PP-Copo)

Description (definition)

Polypropylene copolymer (PP-Copo) is a variant of polypropylene that is produced by the copolymerization of propylene with other monomers such as ethylene. This gives the material higher impact strength and flexibility compared to polypropylene homopolymer (PP homo). PP-Copo is often used in applications that require robustness at low temperatures or a certain elasticity, such as in the automotive, packaging and household appliance industries.

Example

A typical example is the use of PP-Copo in vehicle bumpers. Its high impact strength at low temperatures makes it ideal for the automotive industry.

In the automotive industry, PP-Copo is used for applications such as bumpers, interior trim and air ducts. It offers a good combination of flexibility, impact strength and temperature resistance, which makes it suitable for dynamic applications.

PP-Copo is used in household appliances such as washing machines, dishwashers and refrigerators for flexible components such as seals and hinges. Its chemical resistance to cleaning agents and durability are decisive factors here.

PP-Copo is more flexible and impact resistant than PP-Homo, especially at low temperatures. It is better suited to applications where elasticity is required, while PP-Homo is preferred for stiffer and more stable components.
