    Rectangular heaters
    Rectangular
    Main Feature

    ULTIMHEAT silicone heating elements are made of laminated silicone rubber sheets, vulcanized together through heat and high pressure on both sides of an embedded wire wound heating element. Fiberglass-reinforced silicone rubber gives heater dimensional stability without sacrificing flexibility. Silicone is used because of its high temperature resistance (permanent temperature up to 200°C (390°F), high thermal conductivity (~7 10-4 W/cm.K) and good electrical insulation properties (~12KV/mm) A fiberglass grid, which is visible under the surface, reinforces the silicone rubber sheets. The wire wound heating element web covers the entire surface of the heater. This web could be designed such that holes and cut-outs are incorporated on the heater. This construction makes silicone rubber heaters an ideal solution to the requirements of many low and medium temperature applications, which do not conform to the shapes, sizes and dimensions of band, strip, cartridge, tubular and coil heaters.
    Other general particularities of these heaters are:
      - Not affected by vibration or flexing,
      - Precise heating and lightweight
      - Comply to UL94-VO (flame retardant) and ROHS
      - Low Smoke and Low Toxicity
      - Silicone is non-toxic, and moisture and chemical resistant

    Technical Applications

    Some examples of silicone flexible rectangular heaters applications:

    7.Curing of plastic laminates
    8.Computer peripherals such as laser printers, copy machines
    9.Medical and massage heating pads
    10.TV and radars parables deicing

    Technical Features

    Length: in standard 100 to 400 mm (4 to 16"), on special order up to 1000 mm (40")
    Width: in standard 100 to 400 mm (4 to 16"), on special order up to 1000 mm (40")
    See our band heaters page for width less than 100 mm (4")
    Dimensional tolerances:
    • 0 to 150 mm (0 to 6 inches): +/- 1.5 mm (+/- 1/16 inch)
    • 150 to 500 mm (6 to 20 inches) : +/- 3.5 mm (+/- 1/8 inch)
    • 500 mm to 1000 mm (20 to 40 inches): +/- 5 mm (+/- 3/16 inch)
    Tighter tolerances are available on custom designs if needed

    Standard heater thickness without adhesive, leads output thickness not included:
    1.60 mm +/- 0.15 mm (0.065 inch +/- 0.005") .Add 0.1 mm (0.005") to above dimensions for foil backing.

    Maximum total thickness over leads (horizontal wires output):
    • AWG 22 (0.3 mm²) 0.15" (3.8 mm)
    • AWG 20 (0.5 mm²) 0.16" (4 mm)
    • AWG 18 (0.75 mm²) 0.17" (4.2 mm)
    • AWG 15 (1.5 mm²) 0.19" (4.7 mm)

    Silicone foil minimum bending radius:
    0.125" (3.2 mm)
    Standard Weight: 0.24 gr/cm² 240 g/m² (8 oz./ft²)
    Ingress protection: IP65
    Maximum operating temperature: peak 220/230 °C (446°F), continuous: 200 °C (390 °F)*
    Even if silicone heaters can be used at higher temperature, we recommend for a safe and durable use that maximum permanent surface temperature on silicone should not rise more than 160°C and maximum acceptable peak temperature should not rise more than 200°C.
    Minimum ambient temperature: -60 °C (-80 °F)*
    *These maximum and minimum temperatures apply to silicone heaters only. Restriction will apply for controls
    Voltage: 12V to 600V, AC or DC (UL rating is 600 VAC, TUV recognition is max 250 VAC)
    Resistance tolerance: -5%/+10% (tighter tolerances are achievable)
    Power tolerance: -10% to + 5%
    Watt density: The limitation factor is the heating foil maximum acceptable temperature. This temperature is dependent upon three factors:
      - Temperature exchange with ambient or surface
      - The maximum operating temperature
      - Heater temperature control

    If the element is temperature controlled sufficiently or the heat is taken away by forced air or a heat sink, the Watt density can range up to 0.8w/cm², (5.2 w/inch²). More typical designs are equal or below 0.4w/cm², (2.6 w/inch²)
    Standard watt density:
    • 0.2 w/cm² (1.3 w/inch²)
    • 0.4 w/cm² (2.6 w/inch²)
    • 0.8 w/cm² (5.2 w/inch²)
    Quality control routine tests: Each element is 100% tested for continuity, resistance and insulation. Tests are made according to EN 60335-1 and EN 50106 standards
    Dielectric Strength: 1500V AC, 2s, 0.5 mA (single insulation models) or the typical approval agency recommendation of 2 x input voltage +1000 volts.
    Insulation resistance: More than 10 Mohms
    Surface temperature: Temperature that the silicone rubber heater will attain when suspended in still air at 70 °F (20°C) depends of the watt density. Below 5.2 w/inch², (0.8 w/cm²), the temperature will rise during some minutes and stabilize at a temperature below the critical 500 °F (260°C) which is the highest technically acceptable surface temperature.
