main application:
her is a symmetrical aromatic diol chain extender, because it has good compatibility with mdi, her is widely used in cpu, mpu tpu products. this material has been approved that it can maintain maximum endurance, elasticity 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). her offers better tear strength, initial strength, compression set. it has advantages of low shrinkage, cut resistance, low melting point easy handling etc. typical uses of her include seal, mud pipeline lining, skating wheel, shoe part, beverage container, spandex soft rigid packaging materials etc.
