When we produce silicone products, we will inevitably use silicone rubber raw materials, so how to choose silicone raw materials? Generally speaking; The selection of silicone material mainly considers the following points: application environment, physical property requirements, operational performance requirements
Application environment: The application environment of silicone products refers to the objective environment formed by other products with silicone products when they are used, and it is necessary to truly understand the use environment of silicone products and the resulting requirements before it is possible to choose the appropriate silicone raw materials. The application environment of silicone products mainly includes the following aspects:
   Medical, food grade, environmental protection requirements: for applications in direct contact with the human body, the corresponding medical grade standards must be met; Silicone products in contact with food should meet the food-grade requirements of the country of application; All silicone products must meet local environmental requirements.
   Matching requirements: When the silicone product is used with other components, it must meet the matching requirements, such as light transmission, electrical performance, etc.
   Service life requirements: Most silicone products need to be used for a long time, and some application environments are very harsh, which requires the selection of appropriate silicone raw materials.
Operating performance requirements:
   The choice of silicone material shape: the choice of liquid silicone material or solid silicone material mainly depends on two factors. On the one hand, which silicone material can meet the requirements of the above application environment and physical properties; On the other hand, the existing equipment can support the production of silicone materials. Once the solid silicone material or liquid silicone material is selected, the corresponding production process is determined.
   Fluidity (plasticity) requirements: silicone products have a certain shape, so there are requirements for the fluidity and plasticity of raw materials. Special attention should be paid to the special-shaped parts, the liquid silica gel should choose the raw material that is easy to flow, and the solid silica gel should choose the raw material with high plasticity.
   Operation time: liquid silica gel raw materials will be automatically cured after mixing, in the beginning of the adhesive viscosity before the rapid rise of this period of time is called the operation time, different process requirements of the operation time is different, the selection of liquid silica gel material should be selected with the appropriate operation time of liquid silica gel material.
