Flexible Heaters

Flexible Heaters

Flexible Heaters

Available in virtually any size, shape or configuration!

Flexible Heaters are made from a variety of materials such as Silicone rubber, Kapton, Mylar, or Neoprene and have etched foil or wirewound resistance elements. Fast responding with excellent heating profiles, these heaters solve many tough equipment heating challenges. Custom shapes and terminations are designed to suit. Rapid prototype service available.

Features:

  • Available in silicone rubber, polyimide (Kapton®), mica, fiberglass rope, flexible tape, flexible silicone tape, and aluminum foil.
  • Can be pre-formed and bonded to part.
  • Various types of hardware and fasteners available.
  • 120, 240 VAC standard. Custom voltages available.
  • Distributed wattage available.
  • Wide variety of lead wire configurations. 

SILICONE RUBBER

SILICONE RUBBER A non-reactive, stable, and resistant material used in environments up to 235°C. Thin, lightweight, and flexible, this rugged insulator is moisture and chemically resistant providing longer heater life. A wide array of heater applications use silicone as the base material with temperature being the limiting factor. They improve heat transfer while reducing wattage requirements. Silicone rubber heaters are designed with either wire-wound, etch foil, or laser cut Inconel resistors.

POLYIMIDE (KAPTON®) HEATERS

Utilizing polyimide’s high heat resistance, these heaters have a diverse application such as fuel cells, displays, aerospace, military, medical diagnostic, and analytical devices. Polyimide heaters can be as this as 0.007”, which excludes any type of adhesives. The circuit is pressed between two layers of polyimide film.

FIBERGLASS & SILICONE ROPE HEATERS (GLASROPE®)

Woven fiberglass braid allows this special design to withstand high temperatures of up to 648°C with stock available for quick shipment. They can be used in laboratories, high heating of gas-line tubes, biomedical, and many other uses where high heat is required for challenging geometries.

FIBERGLASS & SILICONE TAPE HEATERS

Built with AMOX yarn with 37 to 40 gauge resistance wire, the 2-layers allow the heater to exceed temperatures over 750°C (fiberglass only). When using heating tape the element expands in multiple directions rather than in a singular pattern eliminating thermal growth. The tape is knitted preventing tensile stress when stretched. All heaters have 24” lead wires standard.
