HER is a symmetrical aromatic diol chain extender with good compatibility with MDI. Widely used in mixing, casting, and thermoplastic PU elastomer products. This material has been proven to maximize the durability, elasticity and plasticity of the elastomer and to minimize shrinkage without contamination. At the same time, in addition to the advantages of aromatic chain extension, the material also avoids the lack of rapid crystallization of HQEE under slightly cooling conditions, providing better plasticity, tear strength, initial strength, Shore hardness, compression set, Special advantages such as fracture deformation and low shrinkage, cut resistance, good flexibility, impermeability, low melting point and convenient operation.

Application:

Such as cast wheels, seals, pressed mats, non-bonded tires, mud tube liners, skateboard wheels, shoe parts, beverage containers, spandex and soft and rigid packaging materials.
