RHENOFIT® TAC/S

Product Description

Rhenofit® TAC/S is a highly efficient co-agent for peroxide vulcanization, based on triallyl cyanurate (TAC) bound to silica. TAC reacts with polymer radicals during curing, creating additional crosslink sites for a tighter network. This improves crosslink density more effectively than increasing peroxide dosage alone.

Vulcanizates formulated with Rhenofit® TAC/S exhibit superior hardness, tensile strength, modulus, and abrasion resistance without compromising storage stability or processing safety. It is particularly recommended for black EPDM compounds with medium to high filler content and CM compounds with moderate filler levels. The powder form ensures easy incorporation, dosing and uniform dispersion.

THESE SPECIAL FEATURES MAKE RHENOFIT® TAC/S SO SUCCESSFUL

• Efficient crosslinking - enhances cure density without excess peroxide

• Improved mechanical properties - hardness, tensile strength, modulus, abrasion resistance

• Stable processing - no negative impact on scorch or storage stability

• Clean processing – low dusting grade for safe handling and uniform dispersion

• Targeted compatibility - ideal for filled EPDM and CM compounds 

THE MOST COMMON AREAS OF APPLICATION

• Molded and extruded technical rubber goods

• Profiles, seals, cable coverings, and bushings

• EPDM-, EPM-, and CM-based compounds for automotive and industrial use

• Applications requiring high mechanical strength and durability
