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, conveyor belt, hydraulic cylinder seals, many other PU products and spandex. 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 (TDIMDIADI). The chain extender is usually a short chain of diamine or diol. MDI prepolymers are usually extended with diols.

Storage: HQEE is very sensitive to moisture, it should be stored in a dry location.

Packaging: Net 20kg fibre drum with PE liner.
