Industrial Teflon Tape (250 Series)

Industrial Teflon Tape (250 Series)

Industrial Teflon Tape (250 Series) provide an excellent balance of heat transfer, release, and flexibility.


Industrial Teflon Tape (250 Series)

The DuraStick® Industrial Tapes utilize DuraFab® Industrial Fabrics but have the added benefit of an adhesive on one side. These tapes are manufactured from woven fiberglass substrates, possess an optimal PTFE (Fluon®) content, leave a minimal fabric impression, and have a proprietary silicone or acrylic adhesive system. Because of the glass reinforcement, this series of tape is resistant to ?cold-flow?, a characteristic inherent in pure unsupported PTFE films, these tapes are an excellent choice when cut-through, load carrying, or harsh industrial environments require the unique surface characteristics of PTFE. As AFC’s most popular and versatile tape series, DuraStick® Industrial Tapes provide the highest value to customers by offering an excellent balance of heat transfer, release, and flexibility.

DuraStick® PTFE Coated Tape Characteristics

DuraStick® PTFE Coated Tapes are engineered to retain the distinctive properties of PTFE; however, by adding a glass fabric to the matrix, AFC is able to obtain the added benefits of dimensional stability, durability, excellent tensile strength, and extremely low elongation (<1%). The addition of an adhesive on one side eliminates the need for mechanical fastening. Tapes with silicone adhesive operate over a wide temperature range, -100°F to 500°F (-73°C to 260°C), while tapes with acrylic adhesive operate over a narrower range of temperatures, -40°F to 350°F (-40°C to 177°C).
