The demand of various products in the silicone industry is very common in various industries, and the solid-state oil pressure process accounts for more than 50% of the silicone industry. The largest demand can also be said to be the solid-state molding process, which can achieve different hardness materials, and the hardness of the soft and hard also affects the normal use of products. Some silicone often need high hardness materials in daily life, And wear-resistant rubber tire for high hardness products will be some problem phenomenon has become a topic of concern.

There are certain technical requirements for high hardness in the industry of silicone products manufacturers. First of all, it depends on whether the development structure of the mold has a certain impact on the product vulcanization. Secondly, has the exhaust groove of the mold really been pulled well? And the most important thing is whether the high hardness products can meet your needs?

Some customers often want about 60 degrees, but they can't tell the hardness. They can only guess, which leads to the normal use function affected by the hardness of 70 or 80 degrees. Some friends want the material of 90 degrees, but they verbally explain that they only need 70 or 80 degrees. As a result, the hardness of silica gel can't meet the requirements after the mold is opened, Therefore, it is important to understand the hardness and softness of the product. The reason why the hardness and softness of silica gel are divided into ± 5 degrees instead of ± 1 degrees is also its reason.

For high hardness silicone products, in the production process, it is necessary to shorten the time and reduce the temperature. Try to reduce the processing hardness and retain the intrinsic hardness. If the vulcanization time is too long, your sealing ring must be very brittle and easy to tear. You should pay more attention when using it. If your temperature is too high, the probability of corner tearing will increase, The aging rate will gradually increase!
