Applications: 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, conveybelt, hydraulic cylinder seals, many other PU products spandex. LCU elastomers require two principle components: a prepolymer terminated with reactive isocyanate groups a difunctional active hydrogen-terminated chain extender. Prepolymer is a product based on the reaction of polyester polyether with isocyanate (TDIMDIADI). The chain extender is usually a short chain of diamine diol. MDI prepolymers are usually extended with diols.
