TPO Series | Impact-Resistant Thermoplastic Polyolefins (TPO)

Product Overview

The TPO Series consists of high-performance Thermoplastic Polyolefins (TPO), combining polyolefin resins with elastomer modification to achieve the rigidity of plastics and the toughness of rubber. The material provides excellent impact resistance, weatherability, dimensional stability, and lightweight performance.
Designed for applications requiring structural strength, durability, and weight reduction, the TPO Series helps manufacturers improve product performance while maintaining efficient processing and cost-effective production.
Compared with conventional polypropylene (PP) or polyethylene (PE), the TPO Series offers superior low-temperature impact resistance, weather resistance, and surface appearance. Compared with TPV, it is better suited for large structural and exterior components, making it an ideal choice for automotive, appliance, and industrial applications.
