E-429 HQEE is an aromatic diol chain extender having good compatibility with MDI to offer excellent performance in CPU , MPU and TPU polymers to impart better tear strength, initial strength, compression set as well as low shrinkage, cut resistance, low melting point and easy handling.

The toxicity and reactivity of HQEE are less than amine chain extender or cross-linking agent. Since, using HQEE is safer for operators and is environmentally friendly.

Application:

E-429 HQEE offers typical uses including seal, mud pipeline lining, skating wheel, shoe part, beverage container, spandex and soft or rigid packaging materials etc.
