RE ZRO®, the British materials brand redefining impact protection, introduces Impact-Modified Polypropylene (PP), a rigid-grade material engineered for protective hard-shell components operating in demanding, real-world environments. Designed to deliver structural strength without unnecessary weight, the material offers reliable impact resistance across hot and cold conditions, helping prevent cracking or shattering under stress.

Developed for applications including shin guards, helmet shells, sliders, and reinforced inserts, Impact-Modified PP provides the toughness required for repeated impacts while remaining light enough to support speed, agility, and rider comfort.

Rigid protection with real-world resilience

Conventional rigid plastics often struggle in extreme temperatures, becoming brittle in cold conditions or losing performance in heat. RE ZRO® Impact-Modified PP has been engineered with advanced polymer reinforcement to retain flexibility and impact strength across a wide operating range. This ensures consistent performance, improved wear resistance, and dependable protection where failure is not an option.

By re-engineering an established polymer rather than relying on complex multi-material constructions, RE ZRO® delivers a material that balances rigidity, energy absorption, and long-term durability in a single, efficient solution.

‍Recyclable engineering for serious performance

Unlike many rigid protection materials, Impact-Modified PP has been developed with end-of-life responsibility built in. Fully recyclable and optimised for efficient processing, the material supports circular manufacturing goals while maintaining industrial-grade performance. Stable flow characteristics improve moulding consistency, reduce production waste, and extend component lifespan.

For OEMs and component manufacturers, the material integrates seamlessly into standard injection-moulding systems, enabling adoption without re-engineering existing production lines. This combination of performance, process efficiency, and recyclability positions RE ZRO’s Impact-Modified PP as a practical alternative to traditional PP and thermoset plastics.

Engineered to perform, then return to ZRO

Developed in collaboration with TOTO-TOA®, the formulation incorporates proprietary chemistry that enhances toughness while enabling controlled biodegradation in anaerobic landfill environments. Verified biodegradability testing provides credible environmental credentials, supporting responsible material recovery at end of life.

This next-generation rigid polymer reflects RE ZRO®’s wider mission to create protection that performs when it matters most, then returns responsibly at the end of its service life. Already proven in demanding real-world use, Impact-Modified PP is utilised within the ION ARCON HD Pro chest and back protector, where rigid structural performance, repeat impact resistance and low-temperature reliability are critical. The material forms part of a layered protection system designed for aggressive off-road and gravity riding, demonstrating how Impact-Modified PP performs under sustained load, vibration and impact in elite-level protective equipment.

With Impact-Modified PP, RE ZRO® continues to expand its materials toolbox, offering brands and manufacturers a high-performance, recyclable solution for serious protective applications.
