Mica Band Heater Characteristics
Mica Band heaters are an efficient and economical solution for heating plastic process barrels and other cylindrical process equipment. The band is constructed with a mica core wound with resistance heater wire that sandwiched between two pieces of mica and protected by an outer sheath material usually galvanized steel or stain-less steel. There are multiple termination options, and the mica band lends itself to custom design to accommodate different coverage geometries, holes, and notches.
Mica Band Capabilities and Benefits:
- Sheath temperature operates up to 900°F.
- Watt densities are up to 45 W/in² (7.0 W/cm²)
- UL® Component Recognition is available for applications up to 900°F for sheath temperature.
- Good Clamping will assure efficient heat transfer.
- The low mass design allows quick heat-up and a quick response.
- Our design variations provide convenience and heater protection
Mica Band Applications:
- Plastic extruders.
- Injection molding machines.
- Blown film dies.
- Tank heating
- Pharmaceutical industries.
- Food industries.
- Any cylinder heating application
