How to make mold silicone products harder

When we buy a liquid silicone for gypsum mold making  product that feels too soft and does not meet our actual usage needs, what should we do to make it harder? Here's Hongtu Silicone to teach you:
Firstly, how to ensure that the hardness of silicone products in the production process meets the standard:
Generally speaking, the hardness of mold silicone is very important in the silicone production process. If the hardness is not reasonable, it will be difficult for silicone products to meet the quality standards, and if the customer's requirements cannot be met, transactions cannot be reached. Many silicone product factories do not have reasonable control over the hardness of silicone, resulting in a large number of defective silicone products.

So how can we control the hardness of silicone well? Here are some suggestions for everyone first:
General silicone factories do not have their own technology for the hardness of silicone; Most of them require silicone collagen material suppliers to directly provide the required silicone hardness materials. The application range of silicone is very wide, especially for silicone daily necessities such as silicone meal mats, silicone ice grids, etc. The hardness requirements of silicone vary depending on the product. Therefore, the first thing to consider is the application of silicone products. For example, the hardness of silicone meal mats is generally around 30 degrees. If it exceeds 30 degrees, then the silicone meal mat product has poor anti slip function and is not soft enough. If it is a silicone ice grid product, the hardness of the silicone is generally 50 degrees. If the hardness is too soft, it is easy to leak when adding water.
