High impact PP (Polypropylene) refers to a modified form of polypropylene that has enhanced impact resistance properties.
Polypropylene is a thermoplastic polymer known for its high stiffness, chemical resistance, and low-weight characteristics. However, it can be relatively brittle and prone to cracking under impact.
To improve the impact resistance of polypropylene, various additives and modifiers are incorporated during the manufacturing process to create high impact PP. These additives may include elastomers, such as ethylene-propylene rubber (EPR) or ethylene-propylene-diene rubber (EPDM), which act as impact modifiers and increase the material’s ability to withstand sudden impact or deformation without breaking.
High impact PP retains the beneficial properties of standard polypropylene while providing superior impact resistance. It can absorb and dissipate energy when subjected to sudden loads or impacts, reducing the risk of cracking or fracturing. This makes it suitable for applications where impact resistance is critical, such as automotive components, household appliances, packaging materials, and various industrial applications.
