Application
This is a low unsaturated polypropylene oxide ether diol, with a molecular weight of 400-4000. As the basis component for the soft segment structure of polyurethane, it can be used for a variety of polyurethane waterproof products.
Feature
DL series products are mainly used for CASE series products, with a molecular weight range from 400 to 4000. For application, as the molecular weight of the polyol increases, the elongation at break gradu-ally increases while the tensile strength and hardness dec-reases. Users may choose polyether polyols of different molecular weight according to their final product’s request. They can also combine MN-3050DF, EP-330NG10LD76E/10LD76EK , 10LD83E/10LD83EK and EP-3600 in groups to increase the product’s tensile strength.
