Product Description

Rhenogran® Geniplex-70 (zinc dicyanato diamine, ~70% active) is a high efficiency, nitrosaminefree ultra accelerator/activator for sulfur curing systems. It increases crosslink density, shortens cure times, and reduces the decomposition temperature of blowing agents, enabling uniform, finecell EPDM sponge, and reliable processing.

Supplied as a low dusting, polymerbound masterbatch, it disperses rapidly and consistently in the mix. Rhenogran® Geniplex-70 supports nitrosaminefree cure packages, allowing formulators to avoid thiuram/dithiocarbamate systems while maintaining processing safety and performance. For heat-resistant technical parts and cellular compounds, it offers a robust pathway to modern, compliant curing.

THESE SPECIAL FEATURES MAKE RHENOGRAN® GENIPLEX-70 SO SUCCESSFUL

Nitrosaminefree formulation for safer, compliant vulcanization
Ultra accelerator performance – higher cure state at shorter times in sulfur systems
Foam activation – lowers blowing agent decomposition temperature for improved cell structure in sponge compounds
Excellent dispersion – predispersed, low dusting granules for clean processing and consistent results
Broad compatibility – effective with common primary accelerators across EPDM, NR, SBR, NBR and other diene rubbers

THE MOST COMMON AREAS OF APPLICATION

EPDM sponge / cellular rubber (profiles, seals, hose covers) with controlled cell morphology
Automotive and industrial sealing requiring low compression set and heat aging resistance
Technical rubber goods (EPDM, NR, SBR, NBR) designed for nitrosaminefree sulfur curing
