FLEXXCEL Heat Seal Iron

Download Instructions [PDF]

U.S. Bellows manufactures high-performance fabric expansion joints for industrial applications. These expansion joints often require thermal-welding (heat seal splice) in field service. Cost effective and easy-to-use heat seal irons are available from U.S. Bellows for use with FLEXXCEL materials.

The main function of a heat seal iron is to introduce enough heat to allow a proper bond between PTFE surfaces of FLEXXCEL materials. The melting point of PTFE is around 621°F (327°C). However, the setting of a heat seal iron is determined by factors like ambient temperature, thickness of bonding materials, and the surface upon which you heat seal. Applying pressure can help facilitate a good bond, but in order to achieve a correct bond, the melting point of the U.S. Bellows FLEXXCEL materials must be achieved.

Safety Precautions

Experience has shown fluoropolymers can be processed and used at elevated temperatures without hazard if proper ventilation is used. Make certain all heat sealing is performed in well ventilated areas. Make certain the heat sealer is safely handled during use. The heat sealer temperature will reach 725°F in normal operation. Special care must be taken with the heat sealer during handling due to the high temperature.

FLEXXCEL Heat Seal Iron Operation

Heat Seal Iron Kit

To operate the Heat Seal Iron, follow these instructions:

  1. Plug the unit into an electrical outlet.
  2. Place the Heat Seal Iron on the FLEXXCEL
  3. Backer Board or another insulated surface.
  4. Push the toggle switch up to the "on" position.
  5. Set the temperature by turning the dial to the desired temperature. A temperature range of 700°-740°F (370-385°C) is typical for splicing FLEXXCEL materials.

The unit contains two lights, a "heat up" light and a "ready" light. The "heat up" light will remain lit until the unit reaches the set temperature, at which point the "ready" light will go on.
