The practicality of physical strength, the function and difference of the hardness and softness of silicone rubber.silicone baby cup custom

　　For consumers who do not understand silicone materials, the physical hardness of silicone rubber products may be ignorant. The product size is the same without too much change, and the relationship between the formula and various physical properties has not been fully understood. All kinds of silicone, rubber and other raw materials have their hardness and softness characteristics, and natural silicone products are no exception, so why silicone materials can be used in all walks of life around the world, officially because of its excellent hardness!

　　Different silicone products have their unique performance and process requirements. For example, silicone sealants and silicone accessories can choose the most suitable polymer and cooperate with them and make reasonable allocations, so as to achieve a close fit and seal in terms of hardness and softness. The functions of shock absorption, water and oil resistance, and the physical properties of hardness and softness are closely related to the formula and raw materials of the product. The debugging of the formula can test the differences and functions in various performances, so the debugging of hardness and softness still needs to be cautious. Be careful, otherwise the error in hardness and softness may cause inevitable troubles!

　　Everyone knows that silicone material has good tensile strength, and the index of tensile strength depends on the hardness and softness of the product. The general hardness and softness of silicone rubber product manufacturers are about 20-80 degrees. The tensile strength is better, generally it can reach about 300%, and the minimum is about 20%, but it still depends on the structure and shape of the silicone product.

　　The indispensable part of silicone material is the tear strength. The silicone rubber material will tear due to stress and other factors. This is one of the inevitable phenomena of all rubber materials, and cracks and cracks are stressed and cracked, which leads to damage. Occupy a minority, because silicone rubber with conventional hardness will basically not have tearing and cracking, and materials with higher hardness are likely to cause tearing due to the spread of cracks!
