With the vigorous development of the organic silicone industry, the technical standards and process requirements of products have been continuously rising. Currently, the liquid silicone processing and molding process has become the mainstream method for manufacturing silicone products. When pursuing high - quality liquid silicone products, the liquid silicone injection - molding process has significant advantages and hardly any obvious drawbacks. Therefore, it is of great importance to pay attention to the current development trends of the liquid silicone processing technology. However, even if the process becomes mature, there are certain limitations in the raw materials for liquid silicone production. Against this backdrop, whether the high - hardness liquid silicone technology is mature or not is worthy of in - depth exploration. Generally, when the hardness of liquid silicone raw materials exceeds 50 degrees, the processing difficulty of products will increase. This is because liquid silicone molding is different from solid silicone molding, and its raw materials are in the form of water - like or paste. When the hardness increases, the mixing and preparation processes become more complicated. Moreover, as the hardness further increases, the tear - resistance of the material decreases. The higher the hardness of the product, the more prone it is to breakage and damage. High - hardness liquid sealing silicone is widely used in numerous products. In today's life, high - hardness silicone products account for a relatively large proportion, and they perform well in terms of both performance and hand - feel. However, many silicone manufacturers are hesitant to use high - hardness liquid silicone materials. The reason is that the feeding speed of high - hardness raw materials in the mold is slow, which seriously affects the efficiency of mold use in the production process and increases mold wear and tear. At the same time, it is also very likely to produce high - quality products. Currently, the solid processing technology has broken through the limitation of 90 - degree hardness. With the increasing maturity of technology, it may even break through 100 degrees or even higher hardness in the future. However, in the liquid silicone production process using high - hardness silicone materials, the technology is still immature. It is difficult to ensure the fluidity and high toughness of the material, as well as the vulcanization time and fluidity without adding any additives, which restricts the material to a low - temperature environment and makes it difficult to achieve a breakthrough. However, judging from the current market development trend, in the near future, high - hardness liquid silicone raw materials are expected to gradually break through this limitation.
