HEC

MOPA E-611 HEC is an aromatic diol chain extender in polymers having good compatibility with MDI and exhibiting great properties for such as high tensile strength and elongation, excellent abrasion resistance, oil resistance and tear strength. Furthermore, the most excellent feature of the polymers is for chemical and moisture resistance, thermal stability, adhesion and toughness with aromatic moiety of MOPA.
