Among many materials, the hardness and softness determine the use value and functional effect of a product, such as hardware and plastics. Different materials have different hardness and price, which also makes the quality of their products impossible. Different hardness and softness determine a main body. Whether the product function is realized or not, and all materials such as metal and marble substances are also refined and blended, not natural mineral processes, and different hardnesses have different differences in terms of production processes.

This kind of problem also exists in the silicone product manufacturing industry. How to distinguish the hardness and softness of silicone materials has become a confusion for many consumers. In the whole process of product design and development, it is impossible to predict how soft and hard materials are needed. Only then can the function be realized, so how to choose the hardness and softness of silicone products?

For silicone materials, the hardness determines whether the installation function of the main product can be realized and whether the buffering and shock absorption effect can be achieved. At present, the hardness of silicone products in different industries basically appears to be 20°-80 °In the middle, but with the research and development of materials in recent years, it can already reach 90° at this stage. Under normal circumstances, the dimensional tolerance range of hardness is ±5°, and manufacturers of relatively fine-grained raw materials can also make adjustments. To ±2 degrees, for some products, the hardness accuracy mainly determines the functional function of the product.

However, at this stage, the basic hardness of the mixed rubber products is relatively high, and the hardness is mainly in the middle of 40-60. Relatively speaking, silica gel is different from metal materials, so the range of dimensional tolerances for both hardness and high precision of the product is relatively large. Manufacturers of silicone accessories can strictly monitor the hardness and tolerances of the finished silicone products, which must be achieved after sufficient time.

For high-hardness silicone products, the hardness of the product becomes more and more brittle, and the tear resistance will increase. The self-separating mold line and its burrs are easy to become brittle, so the structure is one of the most important problems. If the structure Even after the production and processing of very complex products, products with demoulding or right-angle products are prone to damage, so the higher the hardness, the simpler the structure of the product, and the pass rate of products that are too complicated And the usage period rate will be lower.

For silicone products with low hardness, the opposite principle is true. The structure of products with slightly lower hardness can be more complicated and is also conducive to production. Cracks occur during the process, which has a certain relationship with the raw materials. However, low-hardness products in the production process of silicone product manufacturers are very prone to softening and unfamiliarity. It is the right angle that causes the cracking phenomenon.
