The identification of silicone rubber material type is determined through a series of tests and analyses. First, the type of silicone rubber can be preliminarily determined by observing the appearance. Different types of silicone rubber have different colors, textures, and surface characteristics. For example, some silicone rubbers may exhibit a translucent or transparent appearance, while other types may exhibit different colors, such as white, gray, or black.



Second, the type of silicone rubber can be further confirmed by hardness testing. The hardness of silicone rubber can be measured using a durometer. Different types of silicone rubber have different hardness ranges, so their type can be preliminarily determined based on the hardness measurement results.

In addition, the elasticity and ductility of silicone rubber can be evaluated by tensile testing. Tensile testing can measure the degree of deformation and recovery of silicone rubber under stress. Different types of silicone rubber have different tensile properties, for example, some types of silicone rubber have high elasticity and ductility, while other types of silicone rubber may be relatively low.

The type of silicone rubber can also be further confirmed by chemical analysis. The chemical composition of silicone rubber can be determined by using spectroscopic analysis techniques such as infrared spectroscopy or mass spectrometry. These techniques can help identify the composition, structure and functional groups of silicone rubber, thereby determining its type.

In summary, identifying the type of silicone rubber material requires comprehensive consideration of multiple methods such as appearance observation, hardness testing, tensile testing, chemical analysis, etc. to ensure accuracy and reliability.
