Box Cover Mica Band Heaters Features: 1. Especially to heat the cylinders (barrels) on all types of plastic(s) processing machinery. 2. Maximum sheath temperature up to 480 degree C (900 degree F) 3. Maximum watt density = 25 watts /square inches.      Note: In case where high watt densities are required, it is important that all heaters      should be used with appropriate, approved and precise temperature control / sensor      device(s). 4. Insulated shroud conserves energy. 5. Up to 30% of power consumption reduces. 6. Uniform heat distribution. 7. Swift rise in the temperatures of the object to be heated in comparision with plain mica      heaters. 8. Reduction of thermal shocks on polymer melt, resulting in improved quality. 9.  Higher material output is possible, which increases productivity. 10. Good shine of your finished products. 11. Extremely recommended heating elements to save power.
