What Makes Rubber Ideal For the Composition of Electrical Switchboard Mats?

Why are switchboard mats only made of rubber? Why can't manufacturers choose other insulating materials like glass, ceramics, and plastic? We know how rubber is a famous material for residential and commercial flooring. But it sure is renowned for its insulating properties. What makes rubber the best choice for making such a critical safety gear? There is more to it. Read to know more: Role of Rubber in Making Switchboard Mats "Trustworthy" as Protective Equipment Dielectric Strength Rubber has high dielectric strength. Hence, switchboard mats do not break down in a high electric field. IEC 61111:2009 mats have 10kV to 50 kV dielectric strength. Whereas, ASTM D178 matting has a dielectric strength of 6 kV to 50 kV. On the other hand, the IS 15652:2006 mats have 30 kV to 65 kV dielectric strength. Non-Conductivity Owing to the inherent properties of rubber, switchboard matting is non-conductive. During an electric shock, the current tends to pass through the body of the...
