First Rubber TAIC-50P is a pre-dispersed crosslinking coagent containing 50% triallyl isocyanurate (TAIC) on an inert inorganic carrier. TAIC is a trifunctional, symmetric triazine compound (CAS 1025-15-6) that acts as an efficient co-activator in peroxide curing systems. When used together with organic peroxides such as BIPB, DCP, or 3M (29)-50P, TAIC-50P significantly improves crosslink density, increases hardness and tensile stress, enhances heat resistance, reduces compression set (low compression set even after aging), and shortens vulcanization time. It is compatible with EPDM, EVA, CPE, CSM, POE, fluororubbers, HNBR, and silicone rubber. The powder form ensures easy handling and good dispersion. Recommended coagent-to-peroxide ratio: approximately 2:1 (peroxide to TAIC-50P) on 100% active basis. Also suitable for radiation crosslinking systems for rubber and plastics.

Crosslinking Aid Series, Bridging Agent Series
Keywords:
- Chemical composition: Triallyl isocyanurate
- Complex carrier: Inert inorganic substance
- Characteristics: As a polymer crosslinking aid for polymers such as EPDM, EVA, CPE, CSM, and POE, it enhances the crosslinking efficiency when using peroxide crosslinkers 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 and disperses readily.

When you crosslink rubber with peroxides like BIPB or DCP, adding a coagent is often the way to achieve higher crosslink density and lower compression set. TAIC is one of the most widely used coagents for this purpose. TAIC stands for triallyl isocyanurate. Its molecule carries three double bonds that actively participate in radical crosslinking during peroxide cure, tying the polymer chains together more tightly. TAIC-50P is a 50% pre‑dispersed powder, with the active ingredient deposited on an inert inorganic carrier for easy handling and dispersion. When used together with a peroxide, TAIC significantly increases crosslink density. The result: higher hardness, higher modulus, better tensile strength, improved heat resistance, and — importantly — much lower compression set. Seal and roller manufacturers, as well as EVA foam producers, often notice a clear improvement in rebound resilience at elevated temperatures after adding TAIC. In EVA foams, TAIC accelerates crosslinking and shortens cure time. In PV‑grade EVA encapsulants for solar panels, TAIC has become a standard component. It also works well in radiation crosslinking systems, reducing the required dosage. A common starting point is a 2:1 ratio of peroxide to coagent (on active substance basis). For example, 2 phr of BIPB‑40GE contains about 0.8 phr of active peroxide; match it with roughly 0.4 phr of active TAIC, which means about 0.8 phr of TAIC-50P. Always verify with a cure meter for your specific formulation. TAIC-50P is a powder, so keep it dry during storage. Used alongside BIPB, DCP, or 3M peroxides, it can take your existing curing system to the next level.
