For those who don't know about silicone products, it's a puzzle about the production and processing technology of products and the property allocation of raw materials. They don't know much about the hardness of products. Secondly, silicone products are auxiliary peripheral products in nature, so it's inevitable that low hardness may lead to performance differences when cooperating with other materials, So how to adjust the hardness of silicone products?

First of all, in the manufacturing process of all kinds of silica gel products, the raw materials can be replaced or refined before the products are formed, so that the hardness of the products can be further improved. Generally, the suppliers of silica gel products purchase and use the refined rubber directly, so there is no need to adjust the different hardness, And adjust the hardness link mainly or need to understand from the raw material manufacturers!

Increase vinyl content and add silica!

The hardness of silica gel raw materials is mainly made by adding vinyl with different components to blend with silicone resin, silicone oil, silica and other materials, while increasing the content of vinyl is mainly to improve the tightness of silicon chain (at the same time, different components of silica are needed to be ingested, Vinyl is mainly to fuse the silicon chain to get more crystals, and improve its connectivity to improve the hardness. The maximum is 90 degrees, which is the limit. At present, there is no better way to improve the hardness of raw materials for silicone rubber products.

Another way is to improve the hardness of the product from the rubber mixture, but this way can barely improve the hardness of the product, the effect is not too big!

By mixing silica gel with the obtained raw material with higher hardness, for example, if the rubber with hardness of 30 wants to get about 50 degrees, the raw material with hardness of 70 degrees can be added to achieve the hardness of 50 degrees, and the accurate hardness and the same weight of raw material need to be measured in the process of adding. The method is as follows:

1. Adjustment formula for high hardness of silica gel compound (measured hardness value - required hardness value) / (required hardness value - low hardness value) × Weight of compound = weight of low hardness compound to be added

2. Adjustment formula for low hardness of silica gel compound (required hardness value measured hardness value) / (high hardness value measured hardness value) × Weight of compound = weight of high hardness compound to be added
