Does high temperature resistant glue Hongqiang take you to know the hardness of silicone keys? Many customers of silicone keys will be concerned about the hardness of silicone keys. Why? Because you know the hardness, you can know the application range of silica gel keys. Because the places used by silica gel keys with different hardness are also different, it is necessary to improve the hardness of silica gel keys.
Many customers of silicone keys will pay attention to the hardness of silicone keys. When they know the hardness of silicone keys, they basically know the scope of use of silicone keys.
The hardness of silicone keys generally ranges from 30 ° to 80 °. The hardness unit of silicone keys is shore. The silicone keys with this hardness value are generally used in electronic products, electronic toys, other accessories, industrial machinery, household appliances and other industries. This material is insoluble in water and other reagents. It will not react with other substances except special strong bases and acids.        Most of the materials for the production of silica gel keys are silica gel compound, and the production process is mainly oil pressure forming. Therefore, if the hardness is too low, it is not conducive to the material placement of the product. At the same time, bubbles may appear during vulcanization of the compound due to its semi fluidity; Therefore, the hardness requirements for silicone keys are relatively strict high temperature resistant adhesive.
So, why can't the hardness be improved if the hardness range is good? Because if the hardness of silica gel material is above 80 °, the scrap rate of molded products is very high. Why? Because the quality of the product itself becomes brittle, it is not convenient to disassemble, and the production process will become more troublesome. Therefore, the hardness of silicone keys can not be raised so high before production and molding.
