How much can the softest and hardest of silicone rubber products be achieved?
1. The softness and hardness of silicone rubber products can vary according to the process. If it is a liquid silicone rubber process, we can make low-degree silicone rubber products, such as 0 to 20 degrees. Even if we get them, they are very sticky. This type of silicone rubber products are generally very few, and the development of a set of liquid silicone rubber mold is special. It's expensive, and it's usually tens of thousands of dollars less. For some silicone rubber miscellaneous products, the silicone rubber products made by the liquid process are not suitable for self-disassembly, because of the material reasons, which leads to a problem that the product is not smooth and has a burr appearance. Therefore, the liquid process is suitable for making low-degree silica gel products, and does not require self-disassembly is very strict.
2. The other is solid-state technology. At present, the lowest soft degree that solid-state silica gel technology can do in the industry is about 30 degrees, the highest degree is 80 degrees. Although higher degree can be done, but the bad rate is too high, the product is very brittle, and it is not good for self-disassembly. So the most suitable hardness and softness for solid-state process is between 30 and 70 degrees. It can't make softer products, but self-disassembly side is better, the product has beautiful appearance and no burr.
