1)Different shapes: Liquid silicone rubber is in a liquid state with fluidity, while high temperature vulcanizing silicone rubber is in a solid-state without fluidity. 2)Different fields of application: Liquid silicone rubber is generally used in baby products, kitchen products, and medical products, while high-temperature vulcanized is generally used in daily necessities, industrial sundries, and auto parts, with a wide range of applications. 3)Different molding conditions: Liquid silicone rubber is divided into components A and B, and the two components are mixed for molding. when the high temp vulcanized silicone rubber is molded, the vulcanizing agent needs to be added for high-temperature molding.
