PRODUCT FEATURES AND APPLICATIONS
* HER is an aromatic diol chain extender. It can improve tensile, hardness,resilience properties to MDI-polyurethane elastomers.
* HER has been approved that it can maintain maximum endurance,elasticity and plasticity of PU elastomer. It also offers minimum shrinkage.
Besides of those common advantages of aromatic family chain extenders.
* HER avoids the deficiencies in HQEE (HQEE returns solids quickly when temperature drops a little). And HER offers better tear strength, initial strength, compression set. It has advantages of low shrinkage, cut resistance, low melting point and easy handling etc.
*Typical application of HER include seal, mud pipeline lining, skating wheel, shoe part, beverage container, spandex and soft or rigid packaging materials etc
