*Which tape
adhesive is best, Acrylic or Silicone?
Acrylic
DuraStick™ Industrial acrylic tapes have a blue liner and
are the best choice when the tape is to be applied to an ambient
surface where the heat is applied to the fabric. Acrylic adhesives
are aggressive (tacky) at lower temperatures, possess virtually
an unlimited shelf life and operate over a narrower range of
temperatures -100°F to 350°F (-73°C to 177°C),
but can handle the intermittent temperature required in impulse
sealing.
Silicone
DuraStick™ Industrial silicone tapes are furnished with
a yellow liner and are an excellent choice when the tape is being
applied to a heated surface. Silicone adhesives operate over
a wide range of temperatures -100°F to 500°F (-73°C
to 260°C) and are best used within six months of the date
of manufacture. After six months, the adhesive will begin to
crosslink and eventually lose its tack. To obtain the maximum
shelf life, these tapes should be stored in an air-conditioned
room or refrigerated at low humidity.
Products
- PTFE Coated Fabrics
DuraLam® Fabrics
The DuraLam® Series is AFC’s family of flexible, multi-layered laminate fabrics. These fabrics are manufactured using a proprietary process that involves laminating multiple layers of PTFE fabrics and applying of specially formulated topcoats. The finished laminated product contains a fabric matrix that has a higher strength to weight ratio than normal PTFE coated fabrics and a coating that exhibits superior grease, oil and abrasion resistant properties than single ply fabrics and extend the useful life.
DuraFab®
Industrial Fabrics (20 Series)
The DuraFab® Industrial Series is the most extensive and versatile line of fabrics, providing the highest value to customers by offering an excellent balance between heat transfer, release, and flexibility. These fabrics are manufactured from woven fiberglass substrates, possess an optimal PTFE (Fluon®) content, and leave a minimal fabric impression.
DuraFab® Premium Fabrics (21 Series)
The DuraFab® Premium Series is extremely smooth and provides the best release, highest dielectric strength, and greatest chemical resistance and are thus excellent for use in the most challenging industrial applications. These fabrics are manufactured from woven fiberglass substrates, have the highest PTFE (Fluon®) content, and leave little-to-no fabric impressions.
DuraFab® Mechanical Series Fabrics (22 Series)
The DuraFab® Mechanical Series features a more textured surface, and provides the most cost effective solution for applications where a mechanical impression must be transferred to a seal or a surface texture is required. These fabrics are manufactured from woven fiberglass substrates and have a moderate PTFE (Fluon®) content.
DuraFab® Tear Resistant Fabrics (23 Series)
The DuraFab® Tear Resistant Series is specially processed to increase its overall flexibility and tear resistance, thus making it the strongest, most durable line of PTFE coated fiberglass fabrics and are best utilized in high-speed packaging applications or on surfaces where some conformity is desired. These fabrics are manufactured from woven fiberglass substrates, leave a minimal fabric impression, possess an optimal PTFE (Fluon®) content, and have a proprietary additive for flexibility.
DuraFab® Anti-Static Fabrics (24 series)
The DuraFab® Anti-Static Series has the highest thermal conductivity (best heat transfer) of any of the DuraFab® products and is best used in applications where surface static dissipation is desired. These fabrics are black in color and are manufactured from woven fiberglass substrates, have an optimum PTFE (Fluon®) content, and have a proprietary additive.
DuraFab® Premium Kevlar® Fabrics (50 Series)
The DuraFab® Premium Kevlar® Series fabrics have dramatically higher tensile and tear strengths than their fiberglass counterparts and are the best choice for high flex or steam applications. These fabrics are manufactured from woven Kevlar® substrates, possess an optimal PTFE (Fluon®) content, and leave a minimal fabric impression.
DuraFlow® Porous Fabrics (27 Series)
The DuraFlow® Porous Series fabrics possess controlled porosities that allow products to cure and outgas through the fabric. Because of their unique properties, these fabrics are excellent for use in a wide variety of applications, from the manufacture of polymers to a release medium for composite molding. These fabrics are manufactured from woven fiberglass substrates that have been lightly coated with PTFE (Fluon®).
DuraFlow® Mesh Fabrics (27 Series) and UV Resistant Mesh Fabrics (28 Series)
The DuraFlow® Mesh Series fabrics (27 & 28) are unsurpassed in their surface, strength, and airflow characteristics, and thus provide the ultimate performance for drying and curing applications. These fabrics are manufactured from proprietary woven fiberglass substrates that have been heavily coated with PTFE (Fluon®). AFC’s UV Resistant Mesh Fabrics (28 Series) have all the benefits of the 27 Series Mesh Fabrics, but with the added benefit of UV protection.
DuraFlow® Kevlar® Mesh Fabrics (57 Series)
The DuraFlow® Kevlar® Mesh Series fabrics are excellent for heavy-duty or stream related drying applications. These fabrics are manufactured from proprietary woven Kevlar® or Kevlar®/fiberglass substrates that have been heavily coated with PTFE (Fluon®).
*What is PTFE?
Polytetrafluoroethylene (PTFE), a fluorocarbon plastic, is a
plastic in which the hydrogen normally found in association with
carbon in organic materials has been replaced with fluorine.
The resulting polymer possesses a number of unique properties:
inertness to chemicals; fire resistance (will not support a flame);
excellent weathering resistance; low friction (second only to
ice); superior release (anti-stick) properties; flexibility;
extreme heat and cold resistance; outstanding electrical, insulative
and dielectric properties; and resistance to ultraviolet (UV),
infrared (IR), microwave and radio frequency (RF).
DuraFab®, DuraLam® and
DuraFlow® fabrics are used to manufacture an extensive line
of belts and fabricated parts ranging in thickness from .003”
to over .060”. Available with fiberglass, Kevlar® and
Nomex® substrates, these products are fabricated in widths
ranging from ¼” up to 141” (certain fabric styles
only). The normal operating temperatures for these belts are
from –100°F to 550°F (–73°C to 288°C).
AFC manufactures and distributes
a wide range of pressure sensitive tapes to meet the most demanding
applications. AFC’s products range from supported and unsupported
PTFE tapes to Kapton® film tapes, and are available with
various adhesive systems.
