What is the hardness range of silicone products?

The hardness of silicone products is an important physical parameter in the production of silicone products, which involves the final performance and application of silicone products, so what is the hardness range of general silicone products?

The hardness range of silica gel is very wide, and the hardness of silica gel is generally measured by Shore hardness tester, ranging from 10 degrees to 80 degrees.

Under normal circumstances, the higher the hardness of silica gel, the more wear resistance and pressure resistance of silica gel, but the elasticity will be reduced accordingly. On the contrary, the silicone with lower hardness feels soft and comfortable, and has good elasticity.

The difference between the hardness of liquid silicone and solid silicone:

Liquid silicone usually has a low hardness and is suitable for applications where softness and fluidity are required.

Solid silica gel has a higher hardness and is more suitable for making durable finished products.

Different hardness of silicone products application field:

The difference in hardness brings great differences in the application scenarios and fields of silicone products: for example, low hardness silicone is often used in medical equipment and baby products to provide a soft and comfortable touch; High-hardness silicone is commonly used in the automotive and electronics industries to make a variety of seals and protective parts.

Hardness of commonly used silicone products: In daily life, many silicone products have clear hardness requirements. For example, kitchen items such as silicone frying spatula usually require a certain hardness to ensure durability; Protective cases such as mobile phone cases require moderate hardness to provide good protection.

The hardness range of silica gel is 10 degrees to 80 degrees, and the hardness values in this range can meet the vast majority of silicone applications. When selecting silicone products, factors such as hardness, temperature tolerance, chemical stability and processing methods should be considered comprehensively to ensure that the product can play a role in the specific use environment.
