What is liquid calendered silicone rubber?

In industry, liquid calendered silicone rubber is usually used to make sodium silicate sol by ion exchange. It is a translucent milky white liquid with high stability. The silica sol becomes a porous solid after drying. For example, when preparing the (phosphorus molybdenum bismuth oxygen) / silicon oxide catalyst for the production of acrylonitrile by ammoniation and oxidation of propylene, the solution containing active components is mixed with silica sol, and the microsphere catalyst is prepared by spray drying method; It is mainly used as food grade daily necessities and maternal and infant supplies.

Liquid calendered silicone rubber has the characteristics of high and low temperature stability, inert (tasteless and odorless), transparent, easy to color, wide hardness range, chemical resistance, weather resistance, strong sealing performance and compression deformation resistance. Liquid silicone rubber is easier to process than solid silicone rubber. Due to the easy fluidity of liquid silicone rubber, it can be molded, calendered and extruded with low energy consumption. Of course, this also reflects its advantages of high production efficiency. Liquid calendered silicone is injection molding liquid silicone rubber (LSR): the full name is injection molding liquid silicone rubber, and the vulcanization equipment is injection molding machine. The process flow of the injection molding machine is very simple, the product accuracy is high, the output is high (A / b glue is mixed and molded in a few seconds at a certain temperature), and it saves people, electricity and materials. It can produce all the products produced by high-temperature glue, and is a main stream of the development of silicone rubber materials in the coming years. Liquid silicone rubber is a highly transparent and safe food grade material. It is sealed and formed without adding auxiliary materials such as vulcanizing agent.
