Flexible Heater Substrates
The use of thin, flexible silicone rubber/fiberglass fabric composite materials is the standard for high temperature heaters. Arlon manufactures a full line of UL recognized thermally stable silicone rubber/fiberglass fabric composites for use as insulation for flexible heaters. We also offer resistive foil composites, such as Alloy 600/silicone, eliminating the bonding step. Arlon's silicone rubber composites operate reliably and offer long life in both wire wound and etched foil heater applications.
PLEASE INQUIRE ABOUT THE AVAILABILITY OF SHORT ROLLS OF ALLOY 600 (0.001" THICK X 12" WIDE) TO FILL YOUR RESISTIVE ELEMENT NEEDS - No minimum purchases and no need to carry inventory.

Introducing InsilThin™ - Thin Profile Thermal Insulation compatible with Arlon Flexible Heater Substrates
Arlon has introduced a next generation flexible heater compound, 427CR. This UL-recognized compound delivers best in class thermal stability performance. Download our Arlon 427CR Application Note to see detailed test results.
Download the Flexible Heater Insulation Brochure.
RoHS Compliance
Features:
• UL Recognized, see File E 54153
• Broad temperature range: to 450oF continous operation (intermittent to 600oF); maintains properties to -70oF (resists thermal shock, allows quick heatup even in cold conditions).
• Dielectric strength: 400 to 600 volts per mil; resists corona, arc-tracking damage; excellent dielectric fatigue resistance.
• Ozone, weather, chemical resistance: silicone chemistry resists oxidation embrittlement, permits use in hostile environments; resists most harsh weather environments.
• Flame retardant, non-toxic: UL-94 HB and V0 rated options, resists burning; low smoke generating silicones contain no sulfur or nitrogen to emit toxic fumes common to PVC and organic rubber insulation materials.
• Bondable: can be bonded using primers to wire or metal foil elements, as well as to aluminum backers; compatible with silicone pressure sensitive adhesives for bond-in-place systems and silicone RTV adhesives for various field application requirements.
• Ease of fabrication: permits manufacture of heaters to confrom to complex geometries; uncured-rubber acts as its own adhesive.
• Foil laminate: I51576R015 available with prebonded 1 mil alloy 600 foil for etched circuit heater fabrication. Are you interested in other foils? Please contact us.
