Low crosslink density, high compression set, long cure cycles with peroxide alone? First® TAIC‑50GE is a polymer crosslinking aid. Boosts peroxide efficiency, cuts compression set, shortens cure time, enhances heat resistance. Dust‑free granules for EPDM, EVA, CPE, CSM, POE.
  • Chemical composition: Triallyl isocyanurate
  • Complex carrier: EPDM
  • Characteristics: As a polymer crosslinking aid for polymers such as EPDM, EVA, CPE, CSM, and POE, it enhances the crosslinking efficiency when using peroxide crosslinking agents like DCP and BIBP. In peroxide vulcanization systems, it helps increase hardness and tensile stress, improves compression set performance, reduces vulcanization time, and boosts the heat resistance of the final product. Additionally, it is easy to handle, does not generate dust, and disperses readily.

  • Product Description
  • Pain point you may have faced
    You rely on peroxide vulcanization for high‑performance rubber and elastomer parts – EPDM hoses, EVA foams, CPE cable jackets, or CSM roofing membranes. But peroxides alone often give low crosslink density, long cure cycles, and poor compression set. Adding more peroxide increases cost and risks scorch or blooming. You need a co‑agent that boosts efficiency without complicating your process.

    Why TAIC‑50GE is different
    First® TAIC‑50GE (triallyl isocyanurate) is a polymer crosslinking aid specifically designed for EPDM, EVA, CPE, CSM, POE, and similar polymers. It works synergistically with peroxide crosslinking agents such as DCP and BIBP, significantly enhancing crosslinking efficiency. In peroxide vulcanization systems, TAIC‑50GE helps you achieve higher hardness and tensile stress, improved compression set, shorter vulcanization time, and better heat resistance – all while using less peroxide.

    What you gain

    Increased crosslink density – better physical properties without extra peroxide.

    Faster cure – shorter cycle times, higher throughput.

    Lower compression set – parts keep their shape under long‑term load.

    Enhanced heat resistance – vulcanizates withstand higher service temperatures.

    Clean handling – pre‑dispersed granules, no dust, easy to weigh and mix.

    Real‑world result
    A manufacturer of EPDM radiator hoses used DCP alone at 4 phr. Compression set after 72h at 150°C was 45%, and cure time (T90) was 12 minutes. After adding First® TAIC‑50GE at 1.5 phr and reducing DCP to 3 phr, compression set dropped to 28%, T90 shortened to 8 minutes, and tensile strength increased by 15%. The hose passed a stringent OEM heat aging test for the first time.
