Product overview
Silicone flexible foil heaters are among IHP's standard solutions for surface and component heating up to 250°C. They are used where a thin, conformable heating element is required for temperature maintenance, process heating or freeze/condensation prevention.

Applications

• Battery heating
• Heating electronics and telecommunications equipment
• Heating tools and work surfaces
• Climate chambers
• Industrial kitchens
• Laboratory and medical technical equipment
• Composite curing for aircraft structures and wind turbine components
• Piping systems
• Snow melting and condensation prevention

Construction
Silicone foil heaters consist of resistive elements (wire-wound or etched resistance tracks) encapsulated between two silicone layers and vulcanized. Wire-wound construction is commonly used for low-volume or custom layouts; etched-foil technique is used for higher-volume or high-precision patterns. Optional insulating layers can be included to reduce thermal losses and improve temperature control.

Mounting and attachments
Heaters can be supplied with a self-adhesive backing for fast mounting on smooth surfaces. For removable or repositionable installations IHP supplies attachments such as hooks, buckles, eyelets, straps, snap fasteners, Velcro straps (max 125°C) and magnetic backings (max 80°C).

Temperature control and sensors
IHP can integrate sensors including thermocouples and resistive sensors. Sensor pockets are available to simplify installation, replacement or relocation of sensors (for example PT100 sensors or capillary thermostats).
