Application
HQEE is a symmetrical aromatic diol chain extender. It can improve tensile, hardness, resilience properties to MDI-polyureth ane 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.
