Firstly, the hardness of silicone rubber materials is an important indicator for identifying their types. Hardness can be measured using a hardness tester, and the hardness range of common silicone rubber materials is usually between 30 and 80. According to the different hardness values, silicone rubber materials can be divided into two categories: soft hardness and hard hardness. Soft and hard silicone rubber materials are suitable for applications that require good elasticity and flexibility, while hard and hard silicone rubber materials are suitable for applications that require higher hardness and rigidity.
In addition, the chemical resistance of silicone rubber materials is also an important aspect of identifying their types. Silicone rubber materials usually have good chemical resistance and can withstand the erosion of various chemical substances such as acids, alkalis, and solvents. However, the tolerance of different types of silicone rubber materials to different chemicals also varies. Therefore, when identifying the types of silicone rubber materials, it is necessary to consider their tolerance to specific chemical environments.
In summary, identifying the types of silicone rubber materials mainly relies on characteristics such as hardness, temperature resistance, chemical resistance, color, and appearance. By comprehensively considering these indicators, different types of silicone rubber materials can be accurately identified, providing accurate and suitable material selection for application fields.
