As environmental requirements keep rising in the automotive industry, low-odor and low-VOC performance, alongside mechanical properties, have become critical indicators for bumper materials.

Modified PP+EPDM+TD material is a preferred solution for automotive bumpers. It addresses typical drawbacks of neat polypropylene including poor low-temperature brittleness, high molding shrinkage and insufficient rigidity. Widely used in injection-molded front and rear bumpers for passenger and commercial vehicles, it balances crash safety, lightweight design and environmental protection.

The modified PP delivers enhanced impact resistance and low-temperature tolerance. It maintains good energy-absorbing cushioning performance in cold conditions. During low-speed collisions, it absorbs impact energy and reduces risks of bumper fragmentation and splashing, improving vehicle-pedestrian protection. It also features higher flexural modulus and heat-deflection temperature with lower molding shrinkage, minimizing warpage and uneven assembly gaps for large-size molded parts to secure dimensional accuracy. Good flowability suits one-piece injection molding for large bumpers, with favorable surface quality and paint compatibility. It resists sunlight exposure, high-low-temperature cycling and humid environments for long-term stable performance and appearance.

Complying with RoHS and REACH hazardous-substance regulations, high-grade PP+EPDM+TD meets exterior-part service conditions and supports vehicle-level environmental goals. Formulations can be flexibly adjusted. Impact strength, rigidity and melt flow index are customizable for different vehicle models. Beyond bumper bodies, it applies to fenders, wheel housings and other exterior components.
