PU elastomer, also known as polyurethane elastomer, is a polymer synthetic material containing more urethane groups on the main chain. PU elastomers have a wide range of properties, which is closely related to its structure, and its structure depends on many factors such as reactants, reaction time,......
Read MoreLet the PU foam color paste manufacturer tell you the factors that affect the resilience of PU flexible foam! (1) Cell opening ratio. When the opening rate of the product is high, most of the polymers are evenly distributed in the natural open-cell foam meridians, so the resilience of the product i......
Read MorePU foam products are mainly synthesized from polyether, isocyanate, foaming agent, catalyst, etc. The main process of foam formation is generally considered as follows: 1. Generate foam in the polyurethane reaction system by physical and chemical methods, and make the foam evenly dispersed ......
Read MoreSilica gel powder is a colloidal system with solid properties, consisting of colloidal particles that form an aggregated structure. Colloidal particles are polycondensates of hydrated silica gel (polysilicic acid), which are amorphous substances. In reagent column chromatography, the voids of colloi......
