Suitable Hardness of Silica Gel Products

The hardness of silica gel products is the limit value of product performance, but also many customized special silica gel products are concerned by customers. Hardness determines the use and scope of silica gel products, whether it is suitable for the use of the environment and other important indicators, whether it can achieve the desired effect.

In general, the hardness of silicone products is 30-80 degrees, which is relatively common in this range, but few companies process in the 30 degree range, because the hardness in the 30 degree range is beyond the range of solid silicone technology. Currently, our company has a product with a hardness of 10-15 degrees (Dibo silicone manufacturer's product). For this product, we can make it so soft with solid silicone, which is a big step forward in the industry. However, if you want to customize lower or higher silica gel products, due to its particularity, the price will become higher, the production process will become more complex, and the defective rate will be higher. Silicone products are

Silicone products are mostly made of silicone rubber composite, forming process is mostly oil pressing machine. The lower the hardness, not only is not conducive to the placement of the product, but also because of its semi-liquid internal structure in the high-temperature vulcanization process will produce bubbles, and its semi-liquid adsorption is greater, more easily adsorbed dust in the air. Therefore, we have high requirements for the selection of silicone rubber materials for this kind of products, and we must also use the best vulcanizing agent by increasing the power of the vacuum machinery and improving the mold structure.

The forming effect of too hard silicone material is poor, mainly because the product is not easy to mature, it is difficult to process smoothly with ordinary production technology, and the product is poor and incomplete. Moreover, they tend to break during production, adding more production defects.
