As for the customized processing of silica gel bracelet, many friends are not very familiar with the special properties of the product materials and the production and processing technology, so the products produced show the lack of performance and the decline of practical function, while some friends are directly holding the ready-made products to compare the hardness and softness. Now, silica gel bracelet is just over there One of them, how to choose the hardness when the silicone bracelet is customized and processed to the end point!
The selection of hardness and softness of silica gel will produce different performance for different products, and silica gel bracelet is the one over there. Up to now, the hardness of commonly used silica gel bracelet is between 40-60 degrees, and there are certain differences in each hardness. For example, the tensile rate of 40 degree material will reach about 150%, and the hardness of 60 degree material can only reach about 80%. Therefore, it is necessary to explicitly recognize the functionality of the product It is required to clearly recognize the effect of product hard and soft requirements.
High hardness silica gel bracelet is more difficult to produce. For silica gel manufacturers, the higher the hardness of silica gel Bracelet selection, the higher the rate of poor production will be, and the tension of the bracelet will also be affected. In addition, it will cause disconnection no matter what time. Therefore, it is necessary to be familiar with the structure of the product before selecting the high hardness silica gel bracelet jewelry For silicone bracelets, it is recommended that the hardness is not too high.
The most fear of low hardness silica gel bracelet is that the product is soft and the tensile force is not enough to cause the resilience of the product, and the molecular chain of the product loses service. Therefore, to ensure the normal use of the low hardness silica gel bracelet, it is recommended not to stretch for a long period of time, and the low hardness silica gel product needs to be vulcanized before it can be normally molded, such as in the production and processing process of silica gel manufacturers to improve the efficiency If it is not caused by the production process, it is necessary to find out the reason from the raw materials!
Therefore, the hardness of silicone bracelet designed and produced is usually between 40 ° - 70 °.
