Application

TMXDI features a unique tertiary carbon diisocyanate structure. Compared to conventional primary/secondary carbon isocyanates, it offers outstanding advantages including precise reactivity control, high product elongation, excellent thermal and weather resistance, and low toxicity.

With extremely low reactivity toward self-condensation and carboxylic acids, TMXDI enables low-viscosity prepolymers without solvent dilution—making it an ideal choice for fully waterborne polyurethane systems.

Widely used in specialty coatings, waterborne polyurethanes, wood finishes, thermoplastic elastomers, sealants, adhesives, and RIM products.

Trans-CHDI features a compact and symmetrical molecular structure that forms well-ordered hard segments in polyurethanes. This imparts exceptional high-temperature dynamic mechanical properties (low heat build-up), light and color stability, solvent resistance, abrasion resistance, and hydrolysis stability. Softening temperature reaches up to 270°C, with a glass transition temperature as low as approximately -80°C.

Ideally suited for humid, oily, and high-wear/tear environments. Widely used in medical polyurethane elastomers (with dynamic performance and biostability), solid tires, high-temperature-resistant firefighter visors, automotive stop blocks, as well as seals, conveyor belts, hoses, coatings, and films.
