The polymers having very good heat retardancy, flame retardancy and electrical insulation property are utilized for manufacturing insulation covers and cleats. As a result, those polymers yield better safety and better physical properties than others. Mostly polychloroprene, polyurethane and silicon rubbers are used as primary polymer for such kind of application. The formulation is made in such a way that the finished parts can be used n elevated ambient temperature range of -30°C and +160°C. Electrical insulation capacity starts from 6kV or more for one minute and usually flame extinguishing time comes to within 30 seconds from time of removal of source fire. Parts are also optimized to operate in a wide range of humidity giving end user much flexible options. Generally we use customer’s design to manufacture products, however if needed the customized design solution can also be provided.
