The Function and Difference of Silicone Hardness and Softness

Various silicone, rubber, and other raw materials have their own hard and soft properties, and natural silicone products are no exception. Therefore, why silicone materials can be applied in various industries around the world is due to its excellent hardness!

Different silicone products have their unique performance and process requirements, such as silicone seals and silicone accessories from silicone manufacturers. The most suitable polymer can be selected, matched, and reasonably blended to achieve close adhesion, sealing, shock absorption, waterproofing, and oil resistance in terms of hard and soft properties. The physical properties of hard and soft properties are closely related to the product formula and raw materials. Formula debugging can test various performance differences and functions, So hardware and software debugging still needs to be cautious and meticulous, otherwise errors in hardware and software may inevitably cause trouble!

Everyone knows that silicone materials have good tensile strength, and the indicator of tensile strength depends on the hardness and softness of the product. Silicone rubber product manufacturers generally have a hardness of around 20-80 degrees, and the lower the hardness, the better the tensile strength of the product. Generally, it can reach around 300%, with a minimum of around 20%. However, it still depends on the structure and shape of the silicone product.

Silicone materials cannot be missing this is tear strength. Silicone rubber materials will experience tearing due to stress and other factors, which is one of the inevitable phenomena of all rubber materials. Cracks and cracks caused by stress cracking account for a small proportion of the phenomenon of damage, because silicone rubber uses conventional hardness, and there is basically no tearing and fracture phenomenon. Materials with higher hardness are likely to cause tearing due to the diffusion of the crack opening!

So the tensile strength and hardness of silicone products are important indicators of materials. In the vulcanization production procedures of silicone processing manufacturers, the larger the silicon molecular weight of the mixed rubber, the greater the effective crosslinking tensile stress. In order to obtain the specified elongation stress, the crosslinking density can be appropriately increased for materials with smaller molecular weights. Any structural factor that can increase the Intermolecular force. Increasing the density of silicone material can prevent the hardness of the product from affecting its tensile strength!
