Bonding Methods
As part of the manufacturing process, the heater is vulcanized directly to your part. This produces a very strong void-free bond between heater and part, for the best possible heat transfer and extended heater life. When other methods of bonding have caused heater failure, factory vulcanizing can solve the problem. Maximum watt densities can be utilized to reduce heater size, thereby lowering cost.
For a strong permanent bond, a room temperature vulcanizing (RTV) silicone rubber adhesive is used. Heaters can be bonded to your parts at our factory, or we will supply recommendations for proper application.
The maximum service temperature of this adhesive is 220° F (105°C). This adhesive is only used on polyester heaters, and polyimide heaters requiring limited out-gassing. Bond strength is improved if a dwell time of 12 hours is observed before operation of the heater.
The maximum service temperature of this adhesive is 392° (200° C). This adhesive is used on silicone rubber heaters and Kapton® polyimide heaters. Bond strength is improved if a dwell time of 12 hours is observed before heater operation.
Temperature Controls
Hi-Heat can provide heaters with thermostats, thermal fuses, thermocouples, and resistance temperature detectors (RTD) as an integral part of the heater.
Design Variations
Heaters can be designed and fabricated in many types of configurations to fit the size and shape required in your application.
