How to judge the quality of insulating rubber pad

It depends on the quality of the insulating rubber pad. How to judge the quality of the insulating rubber pad? Here are five ways to teach you.
1. No pungent smell is necessary;
Smell the smell of rubber pad. For rubber products, there is an inevitable smell, but the smell must not be too big. If the smell is very pungent and lasting for a long time, it indicates that a lot of waste rubber or recycled rubber is added in the production process of insulating rubber pad. Although good rubber also has some odor, it will gradually fade after being placed in a wide and naturally ventilated area for a period of time.
2. Look at rashen degree, a good insulating rubber pad must be quite malleable;
The insulating rubber pad has the function of insulating layer and eliminating fatigue. If you pull the insulating rubber pad hard, you will feel that it is full of ductility and is not easy to break. That kind of insulating rubber pad can be regarded as a very good commodity.
3. It is not easy to break when it is folded;
Take out a rubber pad, fold it up, loosen it and see if there is any crack. If there is any crack, you don't need to consider it immediately. There are many kinds of easily broken insulating rubber pads, which are made of raw materials with purchasing glue. Such insulating rubber pad will have poor dielectric strength, endanger life safety, and have huge safety risk.
4. Weighing;
Many people think that the heavier the proportion of insulating rubber pad, the better the quality. In fact, it's not. The better the rubber ratio, the harder it is. Because of the high content of rubber inside, there is little residue or no residue.
5. Do the pressure level test.
The insulation rubber pad is paved in the electric power engineering site, which stipulates that the insulation rubber pad purchased by everyone must achieve the required compression level. This can not be ignored!
