Do you understand the principle of silicone products?pacifier holder silicone

　　After purchasing a new silicone product, various problems appeared inexplicably, which made it difficult for our consumer friends to get answers. Therefore, for those who do not often understand the structure of silicone, you can still find the questions you want in the silicone raw materials. The reason is that there will be various process problems in the production process of silicone products, but the process problems can be solved from the silicone products, and the problems in the raw materials should be found by the raw material suppliers when they make the raw materials, so Xiaobian Find out some bad reasons for the use of silicone products for consumers.

　　1. Silicone products appear oily: sometimes in some mobile phone protective cases, silicone wristbands, and products with more comprehensive raw materials for daily necessities, there will be oily products that make the products feel very sticky. This is because the infiltration of raw materials Because of the mixture of silicone oil and white mineral oil, the conflict with silica will lead to the phenomenon of oil out. This product is generally a compound added to make the product tougher and softer.

　　2. Yellowing of silica gel products: The yellowing phenomenon is the essence of ordinary silica gel products. Generally, the products will appear yellowing after being used for too long after environmental changes, but adding anti-yellowing agents can achieve the phenomenon of no yellowing or is Using food-grade silica gel raw materials and fumed silica raw materials, the high-transparency, high-tensile, and high-quality silica gel body will not turn yellow. So the product you buy belongs to ordinary silicone and no anti-yellowing agent is added to cause the product to turn yellow.

　　3. I feel that the pulling force of the product is too poor: the purchased product has poor pulling force, small rebound force and even breaking. This phenomenon can be found from the production of silicone products or from the raw materials. Find the reason, in Among the raw materials, the supplier added too much amino-modified silicone oil, but acid clay was added as a catalyst, which improved the viscosity of the silicone raw material, resulting in the tear resistance and elongation of the raw materials with different hardness, resulting in a shortened product life.

　　4. Why silicone products are not resistant to highly corrosive chemicals: What is the reason why silica gel can withstand high temperatures of about 200 degrees but cannot resist highly corrosive products? In fact, silicone oil is one of the main reasons. Silicon oil can be mixed with vulcanization to make different components. The catalyst reduces its viscosity, and alkaline substances can also be used to increase the viscosity, so adding as little silicone oil as possible to the silicone raw material can avoid conflicts with highly corrosive chemicals.
