RHENOFIT® TRIM/S

Product Description

Rhenofit® TRIM/S is based on Trimethylolpropane trimethacrylate (TMPTMA), a trifunctional methacrylate coagent that significantly enhances peroxide vulcanization. Its three reactive methacrylate groups create a highly crosslinked network, resulting in exceptional hardness, modulus, abrasion resistance, and thermal stability.

Compared to difunctional coagents such as BDMA or EDMA, TRIM provides a higher crosslink density and improved compression set, making it ideal for high-modulus and heat-resistant applications. The low dusting, silica-bound powder ensures safe handling, clean processing, and uniform dispersion.

Compatible with a broad range of elastomers, including EPDM, EPM, NBR, HNBR, NR, SBR, CR, CM, CSM, FKM, FEPM, and VMQ, Rhenofit® TRIM/S is the coagent of choice for demanding technical rubber goods.

THESE SPECIAL FEATURES MAKE RHENOFIT® TRIM/S SO SUCCESSFUL

• High crosslink density – trifunctional structure outperforms difunctional coagents

• Superior mechanical properties – high hardness, modulus, and abrasion resistance

• Excellent heat-aging and compression set performance

• Broad compatibility – works with saturated and unsaturated elastomers

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

• Color stability of finished products

THE MOST COMMON AREAS OF APPLICATION

• Seals, bushings, and hoses for automotive and industrial use

• Extruded profiles requiring high mechanical strength

• Cable insulation and jacketing

• Molded parts exposed to heat and mechanical stress used for technical rubber goods based on EPDM, EPM, NBR, HNBR, NR, SBR, CR, CM, CSM, FKM, FEPM, and VMQ
