Polymer heaters combine resistive heating elements with thermoplastic compounds to create a heated assembly. Polymer heaters in a manufacturing process can make the process more efficient because the polymer heater serves as the heating solution, not just the heating element. It can provide better product performance through uniform heat distribution and by putting the heat only where it is needed. It is resistant to corrosion and scale. It also reduces power consumption. It is used in medical equipment, analytical equipment, freeze protection, and battery heating.
