2019-12-17Parting line Determining the location of the parting line is one of the first steps in designing a silicone rubber injection mold. Ventilation is mainly achieved through grooves located on the partin......
2019-12-17The structure of the thermosetting liquid silicone rubber (LSR) injection mold is similar to the mold structure used for thermoplastic compounds in general, but there are many significant differences.......
2019-12-17Surfactants are materials that can significantly change the surface tension of a liquid or the interfacial tension between them. Many additives are surfactants. When the refractory castable is mixed, ......
2019-12-13Water-based polyurethane is a stable system that uses water as a solvent to disperse high-molecular-weight polyurethane into water at a high speed. Because of the presence of water, it is very differe......
2019-12-13In most cases, leveling agents and wetting agents are often discussed together. However, in fact, leveling agents and wetting agents are two different products. In some practical applications, levelin......
2019-12-13Wetting and wetting agents Wetting is usually a phenomenon in which a liquid substance has an affinity for a solid and wets, spreads, and penetrates the surface of the solid. The wetting performanc......
2019-12-13In the coating industry, coating wetting agents are divided into two types: substrate wetting agents and wetting and dispersing agents. Among them, substrate wetting agents are used to improve the sur......
