Heterophasic (impact) copolymer, also called block copolymer, is a type of polypropylene copolymer commonly used in polypropylene corrugated boards, automotives, and toys.


To improve impact resistance of polypropylene, ethylene-propylene rubber (EPR) is dispersed in the polymer matrix during the polymerization process to create heterophasic (impact) copolymer.


Impact copolymer has good impact resistance at both ambient and low temperatures, making it suitable for cold weather applications. It also exhibits good long-term thermal stability (aging resistance), making this type of polypropylene ideal for corrugated boards, toys, automotive, motorcycle, and appliance applications.

Features and Benefits of Impact Copolymers

  • Good chemical resistance, good acid/alkali resistance
  • Excellent low-temp impact resistance
  • Excellent long-term thermal stability
  • Good processability

Impact Copolymer Applications

Toughness and flexibility make impact copolymers ideal for toys as it can withstand rough play without breaking. With high impact resistance even at low temperatures, polypropylene toys are safe and durable for both indoor and outdoor use.

Its lightweight nature, ability to withstand various environmental conditions, and high impact resistance and make impact copolymers perfect for polypropylene-based automotive parts like bumpers, dashboards, and panels.

The combination of strength, impact absorption, and flexibility of impact copolymers ensure polypropylene baby safety seats remain structurally sound during collisions while providing enough flexibility to prevent fractures.

With superior chemical resistance and durability, paint buckets and battery cases made from impact copolymers can store a wide range of substances with low risk of leaks or damage even with rough handling.

Impact copolymers are tough, impact-resistant, and easily processable. Caps and closures made from this type of polypropylene provides a reliable seal and can withstand repeated use without damage.

Its strength, flexibility, and lightweight properties make impact copolymers ideal for polypropylene corrugated boards.
