RNP’s cutting-edge additives are designed for sulfur-based curing in diene rubbers, delivering unparalleled performance and efficiency.
Our products started their journey as nano-composites with an inert silica core embedded in a tailored binding medium. Our technology evolved into using a proprietary ionic liquid base as the carrier, allowing full solubility of all of the cure active species in a rubber mix. The heightened availability of cure active species combined with our proprietary formulations allows for unprecedented optimisation of sulphur curing and ensures maximum ease of use, safety and incncorporation into a rubber matrix upon mixing.
Unlike conventional zinc-based cures, our additives enhance cure kinetics and physical properties by forming optimized sulfur cross-links of varying types and lengths without the pitfalls traditionally associated with pushing the rate of cure with conventional cure packages.
They are compatible with a range of accelerator classes, including sulfenamides and nitrosamine-free dithiocarbamates.
At RNP, we believe in redefining polymer curing, offering a new perspective on rubber system optimization. Our technology empowers manufacturers to achieve significant cost savings while maintaining or even improving product quality. Our dedicated R&D team is passionate about guiding industries through this transformation, helping them fine-tune formulations for optimal performance.

Respirable dust is a major challenge in industries like mining, posing serious health risks to workers. The smaller the particles, the more dangerous they become. That’s where PEGSIL comes in.
Designed for maximum efficiency and safety, PEGSIL is easy to use—simply dilute with water before wet scrubbing for a powerful, cost-effective solution. With ultra-low dilution rates, it minimizes waste while delivering superior dust suppression.
But PEGSIL doesn’t just protect workers—it also protects the environment. Biodegradable and sustainable, it helps mines reduce water consumption while maintaining operational safety.
By cutting harmful particulates and improving air quality, PEGSIL can even enhance mining output without compromising safety. Cleaner air, safer workers, and greater efficiency – experience the PEGSIL difference today!
