FEATURES & APPLICATIONS
HQEE is a solid aromatic diol chain extender with symmetrical molecular structure. It is recommended applied with MDI-prepolymer. HQEE/MDI system has longer pot-life than MOCA/TDI and MOCA/MDI systems. HQEE-based polyurethane elastomer has higher tensile strength, tear strength, heat resistance, compression set, hardness and resilience than that chain-extended with aliphatic diol. HQEE can be used in casting polyurethane elastomer systems where the superior performance is required. The application includes oil well seals, forklift tires, seals for hydraulic cylinders, conveyor belt, etc. HQEE is also recommended used in high performance thermoplastic polyurethane elastomer, heat-resistant Spandex and millable polyurethane elastomer.
