There are many types of rubber products on the market today, and their uses vary. Therefore, their standards are also different. Here, we will briefly introduce some of the standards for rubber products. First is the hardness of rubber products. In many fields, when using rubber products, particular attention is paid to the hardness of the rubber, and the hardness coefficient must meet national quality standards.

In addition to hardness, there are also very strict standards for liquid resistance because many rubber products are used in contact with liquids, so they must have strong resistance to these liquids. These two standards for testing rubber physical properties are aspects that companies pay the most attention to.
