SiliconeSoft is good, or hard is better? In fact, this is about two types of silicone: liquid silicone and solid silicone. According to the data analyzed by the editor, liquid silicone products tend to be softer, whereas solid silicone products are generally harder. Regarding the different materials of these two types of silicone, I've also consulted some industry experts in the silicone field. They explained that it's due to the diverse nature of silicone materials, and since silicone is also an environmentally friendly and non-toxic option, the demand for customized silicone is increasing, and its applications are becoming more widespread.
The interaction between rubber molecules hinders the movement of molecular chains, manifesting as viscosity or粘度. Therefore, the characteristic of rubber is that it possesses both elasticity and viscosity. Factors affecting elasticity include deformation size, exposure time, and temperature. When the interaction between rubber molecules increases and the regularity of molecular chains is high, it is more likely to produce tensile crystallization, which is beneficial for strength enhancement and exhibits high elasticity. In general rubber, natural rubber and isoprene rubber have good elasticity, followed by nitrile rubber and chloroprene. Butyl rubber and styrene-butadiene rubber are较差in terms of elasticity.
Now, you might be wondering why we're talking so much about flexible knowledge. SuperTech is here to tell you that the hardness of silicone products, in fact, refers to their elasticity. The hardness of silicone products is determined by their type. For example, liquid silicone, also known as liquid-state silicone, can be used to make silicone products with low hardness, ranging from 0 to 20 degrees. They feel soft to the touch and are very sticky. Such liquid silicone products are quite rare because the mold development for liquid silicone products is quite expensive.
What you've saidLiquid SiliconeIs it thermal grease? This is a paste material; is solid silicone the same as thermal silicone sheet? If so, the thermal conductivity of these two products is different: if the thermal conductivity of thermal grease is 1, it is equivalent to a thermal conductivity of 2 as indicated by the thermal silicone sheet. The corresponding products used are also different: thermal grease can be used on high-power heat-generating chips, while thermal silicone sheets are only suitable for low-power heat-generating chips.
Thermal conductive grease boasts superior heat dissipation compared to silicone sheets and greater stability. The advantages of silicone sheets lie in their ease of use and ability to fill larger gaps on heat-generating devices. When double-sided adhesive is applied, they can stick to heat sinks (replacing thermal grease). The basic difference is that one is a liquid and the other is a solid, with different applications. The essential difference between liquid silicone and solid silicone is that liquid silicone is a liquid (can be cast or injection molded), while solid silicone is a solid and can only be molded. The distinction between the two products is that liquid silicone can produce a wide variety of products, depending on the mold, allowing for products like two-shot injection molding. Solid silicone products tend to be more limited in variety!
