application
this is a low unsaturated polypropylene oxide ether triol, with a molecular weight of 3000. it can be used for a variety of waterproof polyurethane products, effectively improving the tensile strength of the polyurethane products.
feature
it can not be used to produce flexible polyurethane foam, as it may cause sponge heartburn.
