Mica Band & Flat Heaters – Practical Selection Guide for Pakistani Factories
In plastic processing, packaging, and extrusion machines, mica heaters are widely used because of their fast heating and cost-effective performance. However, incorrect selection often leads to uneven heating, frequent failures, and energy loss — especially during winter in Pakistan.
This guide explains mica band and flat heaters, their shapes, sizes, wattage, voltage options, and correct industrial use.
What Is a Mica Heater?
A mica heater is a resistance heating element sandwiched between mica insulation sheets and enclosed in a metal sheath (usually stainless steel or galvanized steel). Mica provides excellent electrical insulation and allows quick heat transfer.
