The finished product produced by silicone miscellaneous parts determines the hardness of the product by the way and environment of use. In many cases, the key to the effectiveness of selecting a silicone rubber product depends on the effectiveness of the formulation method, but occasionally the key effectiveness of a product may also be its shape pattern or hard and soft level, and if you want to customize silicone rubber products, you need to match the hard and soft level. Many design product styles are very satisfactory, but the effectiveness of selecting soft and hard is usually different, in particular, silicone rubber products with large right angles of special-shaped parts need to pay attention to multiple situations in the selection of hardness!

Everyone knows that the harder the material, the more brittle it will be. If it is used reasonably, it is impossible to have the above situation. For example, tungsten steel in steel, the material with high hardness is brittle, so inSilicone MiscellaneousThere is also a similar situation in the product manufacturing industry. The higher the raw material of silicone products, the greater the probability that they will become brittle, and the probability of fracture and damage will be greater when the shape of the products is very brittle. Therefore, for special-shaped silicone rubber products, the most important thing to pay attention to is that the products with high hardness are too brittle!
However, the use of high hardness of raw materials to make custom-made can achieve different improvements. In the commodity mold structure, the bevel mouth of the commodity is cut to slightly improve the bevel mouth of the commodity mold.RAngle out, in the process of reasonable manipulation of heat, the commodity manipulation in the standard temperature range of manufacturing, do not have to be too brittle situation, can avoid the situation of tearing crack!

In addition, many high-toughness silica gel products have not achieved expected results in self-disassembly. For example, after 80-degree raw materials are self-disassembled, burrs may be broken and unconnected in the process of edge disassembly. The key is caused by two factors. One of them is that the chemical structure of white carbon and black is too over-distributed due to the material condition of the raw materials. In short, the purity of the raw materials is not high enough, the second is that the vulcanized rubber lasts too long when the silicone product manufacturer is manufacturing, causing the product to become brittle!
