In the silicone products industry, we often meet customers who ask the question, "Is there any relationship between the hardness and temperature of silicone products? How to test the hardness of silicone products? Cushman & Wakefield Electronics will introduce the relationship between the hardness and temperature of silicone products and how to test the hardness of silicone products today.

  The hardness of silicone rubber is the same as the hardness of ordinary rubber, which is distinguished by Shore hardness, generally the higher the degree of hardness, the harder the hardness of silicone raw materials can reach 0 degrees - 90 degrees. Silicone raw materials are divided into solid silica gel and liquid silica gel, solid silica gel (mixed silica gel) hardness can reach 20 degrees - 90 degrees, commonly used for 30 degrees - 70 degrees. And if you want to demand lower hardness silicone raw materials, then you need to use liquid silicone, liquid silicone hardness is 0 degrees -20 degrees, commonly used for 10-20 degrees.
        So will the hardness of silicone products change after molding? About this question, we can answer for sure, the hardness of silicone products and silicone raw materials after molding is the same, and the hardness will not change.
        How to test the hardness? Use a hardness tester, put the silicone products flat and then press down on the center of the silicone products to measure the exact silicone hardness. Of course, if there is no equipment conditions to test the hardness, I have a series of professional instruments and equipment can test the hardness, material and quality, etc..
        To sum up: the softness and hardness of silicone are generally adjusted, hardness and temperature have little to do with each other, can be okay, the difference is not big. Temperature is only related to the curing time, low temperature curing slow, high temperature curing fast.
