Product Details
Introduction
KT HQEE is a solid aromatic diol chain extender with symmetrical molecular structure. It needs to be melted before use. It has good compatibility with MDI prepolymer, especially when used in MDI series PU products. Compared with MOCA, it can effectively extend the life of the kettle and facilitate operation. Compared with aliphatic diol chain extenders, it can significantly improve the tensile strength, tear strength, heat resistance, compression deformation, hardness and rebound performance of the products. PU elastomer products using this product are generally used in fields with high requirements for product physical properties, such as oil well seals, forklift tires, hydraulic cylinder seals, conveyor belts, large seals for heavy industrial machinery, etc.

Application
KT HQEE can be used to produce cast polyurethane elastomers. HQEE/MDI polyurethane is a cast PU elastomer system parallel to MOCA/TDI polyurethane.
KT HQEE is also used in the production of high-performance thermoplastic polyurethane elastomers and heat-resistant spandex. It can also be used for mixing polyurethane elastomers.
