Toluene diisocyanate series

Product Inquiry: Manager Gan 18553303608

Product Introduction:

This product is a compound, a mixed system composed of two isomers: 2,4-toluene diisocyanate and 2,6-toluene diisocyanate. Depending on the 2,4-toluene diisocyanate content, it is divided into three types: TDI65, TDI80, and TDI100. The product is characterized by low acidity and low hydrolyzable chloride content, meeting the requirements for the preparation of various polyurethane materials.

Performance and Applications:
TDI65 has high structural randomness, low melting point, is not easily crystallized in winter, and has fast reactivity. Used in various polyurethane foam products, it effectively improves the uniformity and fineness of the pores, increasing the foam's hardness and strength. It is widely used in various foams, insoles, and curing agent products.

TDI80 is a conventional toluene diisocyanate with strong versatility and is widely used in various polyurethane elastomers, coatings, adhesives, and foams.

TDI100 contains more than 98% 2,4-toluene diisocyanate, resulting in a more regular structure. The polyurethane prepolymer prepared from it has more controllable reactivity, a longer open time, and high process tolerance. Polyurethane products made from it have higher mechanical properties, oil and wear resistance, and are widely used in polyurethane elastomers, high-grade coatings, and photocurable products.
