200°C (392°F)
Silicone Rubber Pad Heaters
Flexible. Precise. Built for Real-World Demands.
When you need to apply heat exactly where it’s required — on flat surfaces, curves, cylinders, or complex geometries — Caliente Silicone Rubber Pad Heaters deliver unmatched versatility. Thin, lightweight, and extremely flexible, these heaters conform to your equipment while providing uniform, reliable heat distribution up to 200°C (392°F) continuous operation.
Why Choose Caliente Silicone Pad Heaters?
Silicone rubber heaters are ideal wherever traditional rigid heaters cannot fit or perform effectively. Their thin profile (standard ~0.056″) and excellent thermal transfer make them perfect for direct surface heating applications.
Two Element Technologies – Choose What Fits Your Needs
Etched Foil Silicone Rubber Heaters
Using custom software, our designers create precision nickel alloy foil patterns that are acid-etched and vulcanized between silicone layers.
Key Advantages:
- Superior heat transfer and exceptionally uniform temperature distribution
- Faster warm-up times
- Longer service life
- Distributed wattage with complex heat patterns possible
- Can be designed to compensate for edge loss
- Accurate reproduction of intricate circuits
- Greater heating element area coverage
Wire Wound Silicone Rubber Heaters
A fine nickel-chromium alloy wire is precision-wound on fiberglass core, then hand-laid onto tooling and vulcanized between silicone layers.
Key Advantages:
- Extremely robust and durable construction
- Parallel circuit options for continued operation even if one path is damaged
- Excellent for high-reliability and high-vibration environments
- Often more cost effective vs etched foil designs
- Molded-to-shape designs for unique geometries
- Pressure Sensitive Adhesive (PSA) backing for easy installation
- Factory bonding / vulcanized attachment
- Thermostats (surface or air sensing)
- Thermocouples and NTC thermistors for precise monitoring
- Custom lead wires, cords, plugs, and connectors (Teflon or silicone)
- Multiple voltage options (low voltage to 1000V)
- Integrated temperature controls and sensors
- Custom shapes, cutouts, and dimensions
- Enclosure heating & freeze protection
- Traffic signal boxes & outdoor electronics
- Battery heating (including EV battery heaters)
- Medical & veterinary equipment
- Lab equipment & lyophilizers (freeze dryers)
- Food service equipment & warming trays
- Military & aerospace (satellites, thermal targets)
- Composite repair & curing
- Sonic cleaning equipment
- Display cases
- Food processing equipment
