RHENOGRAN® HPCA-50

Rhenogran® HPCA-50 is a predispersed crosslinking activator and stabilizer (50% aminic co-activator/antioxidant in elastomer binder) for halogenated rubbers (CR, XIIR, ECO, CO) and acrylic rubbers (ACM, AEM). It enables fast, safe vulcanization and outstanding heat aging resistance. HPCA-50 can fully or partially replace MgO in CR and XIIR compounds, and guanidine accelerators (DOTG, DPG) in ACM/AEM, supporting safer, more sustainable formulations. 

As a co-agent for lead-free curing of epichlorohydrin rubbers, it is used with triazine-based systems. The pre-dispersed form ensures low-dust, easy handling and uniform dispersion.

• Guanidine-free—supports safer, compliant rubber compounds

• Enables fast, reliable vulcanization in CR, XIIR, ECO, ACM, and AEM

• Excellent heat aging and mechanical properties

• No blooming, easy incorporation, and uniform distribution

• Ideal for lead-free curing of epichlorohydrin rubbers

• CR and XIIR compounds for automotive and industrial seals, hoses, and profiles

• ECO, CO, and blends for lead-free cable sheathing and technical parts

• ACM and AEM for engine mounts, gaskets, and high-performance seals

• All halogenated and acrylic rubber goods requiring superior aging and cure safety
