FEATURES & APPLICATIONS
XYlink 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.
XYlink 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. XYlink HQEE is also recommended used in high performance thermoplastic polyurethane elastomer, heat-resistant Spandex and millable polyurethane elastomer.
PACKAGING
Paper cylinder, net weight 20kg, 40kg
STORAGE
XYlink HQEE is sensitive to moisture and sunlight (UV), so keep it storing in airtight container and in a dry ventilated place and keep away from light. Put desiccant inside the package. Make sure the remanent products well sealed after using.
The shelf time is 2 years. If stored over shelf life, it can still be used when the main application properties be qualified by inspecting.
