Bulk Hard Polypropylene Plastic Sheets Boards Electrical Insulated Custom

PP sheets have significant advantages in terms of insulation. They are excellent electrical insulating materials with high volume resistivity, which can effectively prevent the passage of electric current. Moreover, their insulation performance is less affected by temperature, remaining stable within the range of room temperature to 80°C, and is not prone to insulation failure due to changes in ambient temperature. At the same time, they also have good arc resistance, being not easily damaged by arc burns to the insulation layer. In addition, they possess excellent chemical stability; when in contact with acids, alkalis, moisture and other environments, their insulation performance does not decrease significantly, and they can maintain reliable insulation effects for a long time.​

Based on these insulation properties, PP sheets are applied in multiple fields. In the manufacturing of electrical equipment, they are often used as lining plates and insulation partitions for distribution boxes and junction boxes to prevent short circuits or electric leakage. In the electronics industry, they can serve as separation pads for electronic components to avoid interference caused by electric leakage between components. In the field of communication equipment, they are used to make insulation layers of cable protection tubes, ensuring that signal transmission is not affected by external currents. Furthermore, in some humid or corrosive electrical environments, such as insulation panels of electrical operation platforms in chemical workshops, PP sheets can also play an important role relying on their stable insulation performance.
