Specifications subject to change
Versatile Thermofoil heaters allow a
variety of mounting methods.
Proper installation is crucial to heater
performance. The heater must be in
intimate contact with the surface
beneath, as any gaps can block heat
transfer and cause a hot spot resulting
in premature heater failure.

Mechanical clamping is required for mica heaters, optional for polyimide, but not recommended for rubber. Call Minco and ask for
Minco Installation Instruction EI 347 or go to www.minco.com
Factory vulcanization and lamination
See page 13 for information on high-performance bonding of h eaters to mating parts.
With factory-applied PSA, you simply remove
the backing paper and press the heater in place.
Built-to-order shrink bands are pre-stretched
strips of film with adhesive coated ends. Wrap
around the heater and heat to shrink. Stretch
tape installs quickly with no heat required.
Liquid adhesives require more care in applica-
tion than PSA, but generally provide higher
temperature/wattage performance.
Heater Installation
Proper installation en sures good heat flow from
the heater to the heat sink
Voids or bubbles beneath the heater cause
localized hot spots which can result in
premature heater failure
