Among many materials, the degree of hardness and softness determines the value and function of a product, such as hardware, plastics, etc. The price of different hardness of different materials also makes the quality they achieve cannot be achieved. Different degrees of hardness and softness determine the function of a main product. Whether the effect is achieved, and all materials such as hardware and stone materials are the same, they are all refined and modulated, not the natural mineral process, and different hardnesses have different differences in the production process.

This problem also exists in the silicone product industry. How to distinguish the hardness and softness of silicone materials has become a problem for many consumers. In the process of many product design and development, it is impossible to predict how soft and hard materials are needed to achieve functions. Therefore, How to choose the hardness and softness of silicone products?

For silicone materials, the hardness determines whether the assembly function of the main product can be realized and whether the shock absorption effect can be achieved. At present, the hardness of silicone products in different industries is usually between 20°-80°, but with the recent Several years of research and development and progress of materials have reached 90°. Under normal circumstances, the tolerance range of hardness is ±5°, and the raw material manufacturers with relatively fine grains can also adjust it to within ±2°. The accuracy of the hardness mainly determines the functional effect of the product. However, at present, the conventional hardness of mixed rubber products is mainly between 40-60. Relatively speaking, silica gel is different from metal materials, so the tolerance range for hardness and product precision is relatively large. Manufacturers can strictly control the hardness and dimensional tolerances of the finished silicone products, which must be achieved with enough effort.

For high-hardness silicone products, the hardness of the product becomes higher and brittle, and the tearing property will increase. Self-splitting mold lines and burrs are easy to become brittle, so the structure is one of the most critical issues. Products with more complex structures are prone to breakage even after processing is completed and products with undercuts or right-angles are not properly used. Therefore, the higher the hardness, the simpler the structure of the product, and the production yield and service life of products that are too complex. rate will be lower.

For silicone products with low hardness, the opposite is true. The structure of products with low hardness can be more complex and easy to produce and process, and the elasticity of extension is better, while the same tearing properties may occur during stretching. , which is also related to the raw materials, but low-hardness products are prone to softening and immaturity during the processing of silicone products manufacturers, and they will also cause fractures due to oblique or right angles while being stressed in normal use.

Silicone products with different hardness have different functions. The difference in hardness and softness is mainly used as the functional effect of the product. Usually, the hardness of 30°-70° can achieve the best functional effect of the product. If the hardness is low or high, it will cause some The product is inconvenient to process, increasing the cost of the product and the production efficiency.
