| A symmetrical aromatic diol chain extender with excellent hardness, tear strength, and compression set resistance. HQEE imparts good tensile, elongation, modulus and resilience properties to polyurethane elastomers. It is used in elastomers for oil well seals, forklift tires, seals for hydraulic cylinders, conveyor liners, skateboard wheels, and other products where superior physical properties are required. |
