The phenomenon of yellowing of silicone material is often seen in the word of mouth of consumers, but there is a saying that "real gold is not afraid of fire", so it has the same meaning for silicone products. Since there is yellowing phenomenon, as long as it is of high quality Naturally, the material will not become a inferior product for consumers, so for the phenomenon of yellowing and discoloration of silicone protective sleeves, it is generally known from the products produced by regular silicone product manufacturers that yellowing and discoloration will not occur, and the phenomenon of yellowing can be divided into If the time is too long, it will cause yellowing intermittently. One is that it will start to turn yellow after a few days after production. The yellowing phenomenon of transparent products is the most common phenomenon, and the source still needs to be controlled from the manufacturer.
The transparent silicone protective cover turns yellow after being used for a long time. The transparent color is analyzed from the raw material without adding any color glue. The color body is made of silicone material. If no anti-yellowing agent is added to the raw material, the transparent color product will basically turn yellow after long-term use. If the phenomenon is not properly maintained during use, the yellowed area and color will be more obvious. Therefore, in addition to the control of raw materials for long-term use, the control during use is also very important! Professionals know that silica gel does not conflict with any substance. After adding a vulcanizing agent, a compound reaction occurs. After high-temperature molding, long-term exposure to the air causes the product to undergo a physical reaction. The phenomenon of yellowing caused by different climates and environments is different!
Generally, there is also a phenomenon of color change during the production and processing of silicone product manufacturers. This phenomenon is generally caused by the mold temperature being too high, and the product will be deformed and brittle. The phenomenon of yellowing occurs. In this case, the temperature of the mold and the curing time should be controlled, and the curing time should be shortened when the temperature is lowered. It is necessary to find out whether there are too many components added to the curing agent, resulting in excessive fluidity and discoloration and yellowing. Generally, manufacturers They all use anti-yellowing vulcanizing agent, which has good fluidity and is suitable for some appearance parts and transparent products, so the yellowing phenomenon of your silicone protective cover may be caused by the manufacturer using a broken copper vulcanizing agent for vulcanization.
