Product Description |
|
 The DuraStick®
Industrial Zone Tapes utilize DuraFab® Industrial Fabrics
and have an adhesive on the edges of 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 adhesive system. The absence of adhesive
in the center zone allows for faster heat transfer through the
tape, and makes the tape an excellent choice for specific types
of impulse sealing applications, such as the manufacture of plastic
bags. Impulse sealing wires and ribbons are free to expand and
contract without being encumbered by adhesive, helping to extend
their working life. The DuraStick® Zone Tapes are a quick,
easy and economical means of applying a non-stick surface to
heat-sealing platens.

What Are DuraStick® Industrial Tapes? |
|
DuraStick® PTFE Coated Zone 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, excellent tensile strength, and extremely
low elongation (<1). The addition of adhesive strips on the
edges eliminates the need for mechanical fastening. This proprietary
adhesive system is extremely aggressive, has an unlimited shelf
life, and operates over a range of temperatures from -40°F
to 350°F (-40°C to 177°C); while the center, non-adhesive,
zone can withstand temperatures ranging from -400°F to 550°F
(-240°C to 288°C). These tapes have received USDA approval
for food processing and handling, and are FDA compliant (21 CFR177.1550).

Disclaimer: All figures provided in the above table are based
upon ASTM D 4969-97, the Standard Specification for Polytetrafluoroethylene
(PTFE) Coated Glass Fabric. The above tensile values are based
upon the ASTM D902 test method and are not actual values of AFC’s
materials. The above tensile values are 80% of the figures provided
in Table 6 of specification D579. AFC states that its actual
tensile will be greater than the above material specification
and that actual tensile values will be provided upon request.
AFC measures adhesion according to ASTM D 3654/D 3654M, Standard
Test Methods for Shear Adhesion of Pressure-Sensitive Tapes,
and actual adhesion values will vary. Edge Tear values are based
upon ASTM D1424 (Elmendorf Tearing Test) and are average values
that can vary. |
