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.
