[0002] Silicone rubber refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, and the silicon atom is usually connected to two organic groups. Ordinary silicone rubber is mainly composed of silicon-oxygen chain segments containing methyl and a small amount of vinyl. The introduction of phenyl can improve the high and low temperature resistance of silicone rubber, and the introduction of trifluoropropyl and cyanide can improve the heat and oil resistance of silicone rubber. The silicone rubber cutting device is a device that uses a cutter to vertically cut silicone rubber under the action of a hydraulic system.
