Products Usage
HQEE is a symmetrical aromatic diol chain extender. It can improve tensile, hardness, resilience properties to MDI-polyurethane elastomers. HQEE/MDI is a PU elastomer series parallels MOCA/TDI. Finished products as: oil well seals, forklift tires, conveyor belt, hydraulic cylinder seals and many other PU products.
LCU elastomers require two principle components: a prepolymer terminated with reactive isocyanate groups and a difunctional active hydrogen-terminated chain extender. Prepolymer is a product based on the reaction of polyester or polyether with isocyanate (TDI,MDI,ADI). The chain extender is usually a short chain of diamine or diol. MDI prepolymers are usually extended with diols.
Package And Storage
Package:
25kg/carton drum or as your requirements.
Remark: Chemical composition and size can be optimized by the customers' requirements
Storage:
Keep tightly closed. HQEE is hygroscopic and will change color under sunlight. Keep tightly closed and store in ventilated place. Keep away from moisture and sunlight
Safety Protection
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
