Large diameter silicone tube is a hose that everyone often uses, but many people have encountered the phenomenon of rapid yellowing of silicone tube. What is the reason for this?
The yellowing of the silicone tube has a certain relationship with the improper use environment and storage environment, but there are also many customers’ storage environment and use environment suitable for the silicone environment, but the product yellowing speed is still fast.
This shows that the silicone tube products they purchased have problems. The following is a professional silicone tube manufacturer to explain to you what causes silicone tube yellowing in the production process.
The large-diameter silicone tube itself is a product that is not easy to produce in the eyes of many manufacturers. Because of this, the temperature rise of the silicone during the extrusion process causes the generation of high-temperature sulfur, which causes the product to yellow. To put it bluntly, the desulfurization temperature is too high to directly bake silica gel yellow. The addition of sulfur is divided into the front and back stages, which affects the yellowing of the silica gel. In particular, some inexperienced manufacturers are particularly prone to yellowing the product during the production process, because the wall thickness of large-caliber silicone tubes is often thin, and the temperature in the oven needs to be adjusted, and this adjustment process directly affects whether the product becomes yellow. Our company has many years of experience in the production of silicone tubes, which can mechanize and precisely adjust the temperature of the oven to ensure the quality of the silicone tubes.
The quality of raw materials is relatively low, and the raw materials of silicone resin are also divided into excellent, high, medium, and low. If some low-quality raw materials are used, the yellowing speed of the product will be affected. Even under a good working environment, the yellowing speed will be accelerated, which is determined by the raw material itself.
Most of the reasons for the yellowing of the silicone tube due to improper operation of the production process are these. These factors are artificial, and only by choosing a manufacturer with reliable quality like our company can the phenomenon of aging of the silicone tube be avoided to the greatest extent.
