Liquid silicone rubber (LSR) is very low viscosity silicone that can be injection molded or cast into silicone rubber sheets. "Liquid" is explicit in the name to differentiate LSRs from high consistency gum based silicone products. LSRs are addition cure / platinum cure systems in contrast with most gum based silicones that are peroxide cured. In its raw uncured form, LSR is two parts liquid that are mixed together (mixing of Part A and Part B starts the curing) and heated to accelerate the curing process. Raw gum based silicones look and feel similar to clay. LSRs are generally injection molded or cast while gum based silicones are typically compression molded. Note that injection molding of liquid silicone rubber is the inverse of molding thermoplastics; room temperature liquid silicone compound is injected into and cured in a hot mold vs. plastic pellets melted into hot liquid and forced into a cooled mold.
