This material is an impact copolymer polypropylene with a melt flow index ranging from 60 to 70g/10min. It is characterized by its high melt flow index, high modulus, and high impact resistance. Primarily, it is utilized in the automotive industry for components like pillar door panels and bumpers, in home appliances for modified products, as well as in the production of large-scale injection molded items.
1. Excellent performance: High fusing, high modulus, high-impact resistance.
2. High-impact resistance, safe, and odorless, meet the requirements of automotive and home appliance products.
3. Lightweight to meet the needs of more large-scale products.
It can be used for components like pillar door panels and bumpers, in home appliances for modified products, as well as in the production of large-scale injection molded items.
