Liquid silica gel is a type of silica gel as opposed to solid silica gel, but is in the form of a liquid. Liquid silica gels can be classified into liquid silicone rubbers and silica sols by a broad class. By liquid silicone rubber we mean liquid silicone rubber in general. Liquid silicone rubber has better processability than solid silicone rubber. Liquid silicone rubber is often classified into two main classes according to the positions of functional groups (i.e., crosslinking points) contained in the molecular structure: one type is a liquid rubber called telechelic, in which the functional groups are at both ends of the molecular structure; the other is a liquid rubber having active functional groups randomly distributed in the main chain, that is, having functional groups in the molecular structure, which is called a non-telechelic type. The injection machine body 1 can discharge and injection mold liquid silica gel.
