What effect does the hardness of silicone rubber raw materials have on the production of silicone rubber keys?

1. The hardness of common silicone key raw materials is divided into 70 / 50 / 30 degrees. Different hardness can also be produced according to customer requirements.

2. Hardness affects the elasticity (pressing force) of the key. The higher the hardness, the higher the elasticity, the lower the hardness of the raw material, and the lower the elasticity (slightly worse hand feeling). 3. The impact of hardness on the silicone sealing ring: the higher the hardness, the worse the tear resistance and easy to break

4. Effect of hardness on silicone foot pad: the lower the hardness, the better the shockproof effect of silicone foot pad is than that of high hardness

Generally, the hardness of solid-state molded products can be up to more than 80 degrees, but the higher the hardness, the higher the scrap rate of silicone rubber during molding, and the finished silicone rubber products will be very brittle, difficult to remove edges, and may even affect the normal use of customers. Therefore, generally, the hardness of customized silicone rubber products is the most appropriate between 30-80 degrees.
