Silicone rubber is a kind of elastomer material often used in automobile, medical, consumer electronics, electric power and infant and child industries. Generally, manufacturers of silicone rubber products need to mix silicone rubber base materials, additives and pigments in a certain proportion according to the requirements of color and functionality. For example, the obtained silicone rubber premixed materials are qualified after sample preparation, and then further put into extrusion or molding equipment to produce finished products, If it is unqualified, it is necessary to adjust the proportion of each component in the premix before retesting. However, the mixing before the production of products in process not only needs additional equipment input and more varieties of materials, but also may interrupt the automatic production. In addition, for consumer electronics applications that have direct contact with the skin, such as earphone sheath, smart wristband, mobile phone sheath, etc., there may be contaminated links in the mixing process, which may cause the risk of skin sensitization to consumers. In recent years, with the continuous upgrading of automation, digitization and intelligence in the manufacturing industry, as well as the pursuit and attention to efficiency, quality, safety and environmental protection, more and more enterprises hope to save mixing steps, so as to further improve production efficiency and ensure the quality of products and the safety and reliability of sensitive applications.
In this context, Wacker chemical, the world's second largest silicone manufacturer, has launched silmix in China ® Ready to use silicone rubber premix brand, according to the user's color and performance requirements, the base material, additives and pigments are fully mixed evenly, and delivered to the customer "out of the box" after passing the Wacker strict quality control system testing.
