Polyester Etched Foil Heating Elements

An economical alternative for low-temperature, larger-scale applications. HEATFLEX polyester heaters are constructed using an etched foil heating element. Advanced circuit imaging combined with chemical etching allows designers the flexibility to distribute wattage while creating multiple heat patterns in a single heater. Contact Heatron for a design consultation to select the right set of options for your application.

  • Precise heat distribution
  • Superior tensile strength
  • Low outgassing
  • High dielectric strength

Overview Options Specifications Applications
  • UL E91597 (UL 499)
  • Extensive experience with FDA and CE Mark approvals.

Options:

Wattage and Voltage

Custom watt density and multi-zone controls are available for added efficiency. Distributed wattage can compensate for heat loss and create uniform temperature profiles. Polyester etch circuits typically operate from 2 to 240 volts, including dual voltage, and function with AC and DC voltage sources.

Surface Mount Sensors and Thermostats

Heatron offers a selection of sensors, thermostats and thermal fuses that maximize efficiency for your application, and can be incorporated in the assembly process. Sensors can be mounted over heated and non-heated sections. RTDs or thermistors provide direct, onboard temperature feedback and control for more complex heater system assembly.

Connecting Leads

A wide range of connections are available. Typical options include PVC insulated, Teflon® (TFE) insulated, 19-strand silver plated copper conductor, flexible circuits and silicon rubber.

Attachment Methods

Pressure Sensitive Adhesive can be bonded to customer’s part at Heatron’s facility or applied for attachment at customer location.

Value Added Options

  • Ground circuits or wires
  • Three phase power
  • Over-temperature control
  • Special marks and labels
