Structure 1. Insulation rubber pad composition: The insulation rubber pad is mainly made of rubber insulation materials, and is made of non-polar rubber with excellent insulation properties such as NR, SBR, and IIR. 2. Characteristics of insulation rubber pad: There should be no harmful irregularities on the upper and lower surfaces of the insulation pad. Harmful irregularity refers to one of the following characteristics, namely, defects that disrupt uniformity and smooth surface contours, such as small holes, cracks, local protrusions, incisions, inclusions of conductive foreign objects, folds, voids, concave and convex ripples, and casting marks. Harmless irregularity refers to the surface irregularity formed during the production process. A high-quality insulation rubber pad has no odor, bubbles, or pits, and its surface is smooth, tidy, and clean. 3. Measurement of insulation rubber pad thickness: At least 5 different points should be randomly selected on the entire insulation pad for thickness measurement and inspection. Micrometers or instruments of the same accuracy can be used for measurement. The accuracy of the micrometer should be within 0.02mm, the diameter of the measuring drill should be 6mm, and the diameter of the flat presser foot should be (3.17 ± 0.25) mm. The presser foot should be able to apply (0.83 ± 0.03) N of pressure. The insulation pad should be placed flat to ensure smooth measurement between micrometer measurements. The upper and lower surfaces of the insulation rubber pad should be free from harmful irregularities. The harmful irregularity of insulating rubber pads refers to one of the following characteristics, namely, defects that disrupt uniformity and smooth surface contours, such as small holes, cracks, local protrusions, incisions, inclusions of conductive foreign objects, creases, concave and convex ripples, and casting marks. Classified by color, it can be divided into: black insulation rubber pad, red insulation rubber pad, green insulation rubber pad, black green insulation rubber pad, power gray insulation rubber pad. According to the anti-skid type, it is a conventional insulation rubber pad; Anti slip insulation rubber pads (such as anti slip rubber pads, willow leaf anti slip insulation rubber pads, and protruding point insulation rubber pads) are also available as regular insulation rubber pads
