through heat and high pressure on both sides of an embedded specially formed heating wire element. Fiberglass reinforced silicone rubber gives the 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 10-4W/cm.K) and good electrical insulation properties (~12KV/mm)
This compact and economical series is intended to be integrated into a device. The temperature control is carried out by the integrator. Sensors or temperature limiters can be incorporated into the heating surface. Other general particularities of these heaters are:
- Not affected by vibration or flexing,
- Lightweight,
- Comply with UL94-VO (flame retardant) and ROHS,
- Low smoke and low toxicity,
- Silicone is non-toxic, and moisture and chemical resistant.
- Very thin profile.
Main Applications
Combining high surface power and flexibility, flexible silicone heating elements are a simple and economical solution for heating surfaces. They are light, thin, heat quickly and evenly because they are in direct contact with the surface to be heated. Their construction is rugged, and they do not change dimensions during heating. They can be mounted on flat or cylindrical surfaces. Their bonding to the surfaces can be made by vulcanization, room temperature vulcanizable resin (RTV), or by application of a pressure-sensitive adhesive (PSA).
Some typical examples of applications are:
Autoclaves, Surveillance cameras, Mold heaters for polymerization of resins, Poultry incubators, Diesel fuel filters, Defrost, Cash Machines, Laboratory Equipment, Gyroscopes, Laminators, Heated Mirrors, Animal Feeders, Photocopiers, Food heating Trays, Heat Presses, Battery Heaters, Tanks for liquids, etc.They can be made in multiple shapes, receive cutouts or holes. They can receive temperature sensors, temperature limiters, thermal fuses and thermostats.
