Certain thermoplastics are good electrical insulators and offer freedom of design in electrical applications. This table is an indication of which engineering plastic will offer the best or worst performance when used in applications where electrical insulating properties is required.

Please refer to the Technical section of the Dotmar website for explanations of the electrical properties of thermoplastics or contact Dotmar if you require specific technical data.
