Decker Tape Products, Inc. Blue Polyester Film Tape Silicone Adhesive 3" x 72 Yd Case of 16 Rolls

SKU CH-QT7D-N6D68

Case of 16 rolls of 3-inch by 72-yard blue polyester film tape with silicone adhesive, 2.5 mil thick, 20 oz/in adhesion, 20 lbs/in tensile strength, 100% elongation, and 32 to 385°F temperature range

  • Silicone adhesive bonds silicone papers and polyethylene
  • 5 mil film resists chemicals and fumes
  • 20 lbs/in tensile strength handles demanding splicing
  • 100 % elongation conforms to irregular surfaces
  • 32 to 385 °F range suits high-heat masking

Blue Polyester Film Tape for Splicing & Masking

This 3-inch by 72-yard blue polyester film tape uses a silicone adhesive for splicing silicone papers and polyethylene. It also masks electronic parts during manufacturing and helps produce silicone liners. The case contains 16 rolls for high-volume use.

Thermal Resistance and Adhesion Performance

The tape operates across a 32 to 385 degree Fahrenheit range, maintaining bond integrity in elevated heat. A 2.5 mil thickness provides 20 ounces per inch of adhesion and 20 pounds per inch of tensile strength. Elongation reaches 100 percent for flexible application.

Upgrade from Standard Masking Tapes

This product replaces general-purpose tapes that fail under chemical exposure, fumes or sustained high temperature. The jump is worth it when splicing silicone-coated papers or masking circuit boards during processes that exceed ordinary adhesive limits.

Questions about this item

How do I apply the 3" wide tape so the silicone adhesive bonds properly?

Clean the surface thoroughly, then press the 2.5 mil film firmly across its full width; the step often missed is allowing the 20 oz/in adhesive to wet out for several seconds before loading the joint.

What will need replacement after extended use in a 385°F environment?

The polyester carrier and silicone adhesive are rated to 385°F; once the 20 lbs/in tensile strength degrades from thermal cycling, the entire roll must be replaced.

At what point does elongation become the limiting factor during a long splice run?

The tape stretches up to 100% elongation; when a splice approaches that limit the film necks down and adhesion drops, signalling the end of reliable performance.
