FAQ for engineers

Ohmmat flexible heating mats — common questions

When should engineers choose Ohmmat over standard silicone mats?
Choose Ohmmat flexible heating mats when you need repeatable thermal uniformity on complex geometries, tight temperature tolerances, or long service life under mechanical stress (vibration, bending, cycling). In practice, Ohmmat is the better fit for custom silicone heaters where “good enough” silicone heating pads create hot spots, temperature drift, or uneven heat transfer across the surface.
Can Ohmmat be integrated into composite structures?
Yes. Ohmmat can be specified for integration into composite structures and assemblies where engineers need controlled heat for composite curing, bonding, or freeze protection. The key is the co-design phase: geometry, power density, insulation stack-up, wiring exits, and temperature sensing (e.g., RTD / thermistor) are defined to match your laminate, tool, or structure constraints.
How does Ohmmat ensure thermal uniformity?
Thermal uniformity comes from the heater architecture (for example, etched-foil resistor patterns tuned to the target surface) combined with thermally conductive silicone layers that spread heat consistently. Uniform results also depend on the control loop: correct sensor placement, a suitable temperature controller, and the right interface materials to reduce thermal resistance between the heater and the part.

Tip: If you share your target temperature, surface material, geometry, insulation, and power supply, we can advise on heater layout, power density, and sensor/control strategy.
