How to prevent yellowing of transparent silicone products.Tire water bottle Processing

　　The phenomenon of yellowing and discoloration of silicone products is a phenomenon that many consumers are familiar with, but do you think it is normal for silicone products to appear yellowing? Or is there a trace of favor for why it turns yellow?

　　The question of why the yellowing of silicone rubber products occurs. In fact, the yellowing of silicone rubber is not its essence. The raw collagen material of silicone rubber is composed of dozens of millions of molecular crystals. You can change the goods at will to change its composition, so even if hundreds of thousands of molecular chains are not subject to the chemical reaction, there will be yellowing, but it is limited and blocked by the outside world, such as vulcanizing agents, raw materials, anti-yellowing agents, etc.!

　　When it comes to vulcanizing agents, many silicone rubber product manufacturers use ordinary vulcanizing agents, which are applicable to many products, but when they are highly transparent or translucent products, there is often a yellowing phenomenon when the white color is cast, so many silicone rubber manufacturers will choose Anti-yellowing vulcanizing agent and adding anti-yellowing agent can be used in high-permeability and semi-permeable products without discoloration, which can ensure that high-temperature vulcanization produces secondary odor vulcanization without any color change, and the product will not change color after long-term use!

　　In addition, there are certain factors in the raw materials. Generally, the raw materials of silica gel products are mainly made of reinforced silica, and the dosage of silica is used because the material cost is lower, and the performance has different adjustments and changes, so it is necessary to improve the performance. At the same time of other properties, the anti-yellowing effect is affected and changed, so it is subject to more changes as the nature of the material changes, which affects its own quality!

　　On the other hand, the silicone protective sleeve is not prepaid during the use process, and the ordinary precipitation method silicone rubber has the phenomenon of yellowing, so the transparent silicone product will have some yellowing effect.
