Organic silicon industry demand for various products in the industry is very common, and solid state hydraulic technology in organic silicon industry accounted for more than fifty percent, the demand for larger or solid molding process, it may do high and low hardness of different material, and the hardness of hard and soft also affect the normal use of products, some of the silica gel in daily life often require high hardness material, And the silicone seal ring for high hardness of the product will be some problems phenomenon has become a topic of concern for us to use.

High hardness in the liquid silica gel products manufacturer industry is indeed there are certain technical requirements, first of all to see whether the development structure of the mold has a certain impact on the product vulcanization, and then the exhaust groove of the mold really has pulled it? What is more important is whether high hardness products can meet your use requirements?

Some customers often want to 60 degrees or so, but can't distinguish hardness of soft and hard degree can only be guessed at, causing the hardness after the 70, 80 to affect the normal use of the function, the material of 90 degrees, and some friends want but verbally that need only 70 degrees, 80 degrees is enough, the mould out after silica gel hardness can not meet the requirements, So it is important to understand the hardness and softness of the product. The hardness and softness of silica gel is divided into ±5 degrees instead of ±1 for its own reasons.

For high hardness of the silicone seal ring in the process of production need to shorten time, temperature, try to reduce the its processing hardness, hardness nature reserve, if the curing time is too long, you of the sealing ring must be very fragile, it is easy to tear, that will have to pay more attention to when using, if your temperature is too high the product appears the probability of edge tear and get bigger, That aging rate will also gradually increase!

So high hardness products in the process of processing or need certain processing skills. In fact, the main difficulties are the self-deedling of the mold and the exhaust groove. As long as the exhaust effect of the product can be obtained, there is basically no problem after adjustment on the machine.
