Selection of rubber materials for rubber joints in food pipelines
In the past, when people's life and death level is getting higher and higher, food and clothing problems will not appear at all, and the demand for food is getting higher and higher, especially in the past, people often report a series of food safety problems such as gutter oil here, Sudan red there, and so on. So people also pay great attention to food safety, and in food processing plants, There are some rubber joints used in food pipes. The request for rubber materials in such rubber joints is stricter than that. After all, they are used to transport food.
The food grade rubber joint adopts imported silicone collagen materials, applies scientific consumption process, and adopts the intermittent method to stop the consumption of raw rubber. It is a high-quality silicone rubber tube that stops consumption for the characteristics of high tear resistance and high transparency of gas phase rubber, ultra-high and lower hardness of rubber mix, functional rubber mix, etc. This product has more universal compliance. Compared with the silicone hose and silicone profile of the traditional double two four vulcanization process, it has the advantages of high transparency, no smell, no yellowing, no frosting, etc., especially the problem of black rubber hose frosting, and the fading of blue products. It is non-toxic and tasteless, with stable chemical performance. Under normal conditions, except for caustic soda and hydrofluoric acid, it does not react with any acid, alkali or salt. As it is a colloidal structure, it has many micropores and a large specific surface area. The pore diameter of edible silica gel is about 8-10nm. In the test, the specific surface area of silicone rubber is 300-500m2/g, and the surface is hydrophilic. It has a strong ability to absorb water. Under high humidity conditions, its water absorption capacity can reach 80% - 100% of its own weight. Therefore, food grade silica gel can be used as external drying agent for food and medicine. As the edible silica gel is refined and sterilized, it can be directly mixed with food and drugs according to demand to ensure that the food is dry and eaten with food, without any toxic reaction to human body.

Industrial properties of plastic coated hoses?
The inner layer of plastic coated hose is made of stainless steel hose or galvanized hose and special insulation treatment, and the outer layer is made of PVC material (UV resistant and anti-aging).
1、 Product color
