Viton® Fluoroelastomer Sponge Tape | Custom Widths & Acrylic PSA

High-Performance Viton® Sponge Tape: Custom Width Gasketing Solutions

When standard elastomers degrade, swell, or melt under extreme operational stress, engineers and prototyping manufacturers specify one material: Viton® Fluoroelastomer.

For demanding thermal and chemical environments, our custom-width Viton® sponge tape with one-sided acrylic pressure-sensitive adhesive (PSA) delivers instant, reliable sealing. Designed for rapid assembly, this fluoroelastomer adhesive strip is the ultimate weatherstripping and gasketing solution for mission-critical designs.

Why Specify Viton® Sponge Over Standard Elastomers?

While solid Viton® is legendary for its durability, closed-cell Viton® sponge provides the essential compressibility required for sealing irregular mating surfaces, dampening vibration, and creating impenetrable environmental enclosures.

Performance Metric Viton® Sponge / Foam Standard EPDM or Neoprene
Operating Temperature Up to 400°F (204°C) continuous Typically fails above 250°F - 300°F
Chemical Resistance Unmatched against aliphatic/aromatic hydrocarbons, acids, and harsh solvents Swells or degrades when exposed to fuels and strong chemicals
Environmental Stability Exceptional ozone, oxidation, and weathering resistance Vulnerable to long-term UV drying and cracking

Precision Gasket Tape in Custom Widths

Buying master logs of material requires secondary processing, costing your facility time and labor. We streamline your production by supplying ready-to-use gasket tape.

Utilizing advanced slit-to-width manufacturing capabilities, we cut these rolls to your exact dimensional tolerances. Whether you need a narrow 1/4-inch strip for aerospace avionics prototyping or a 2-inch wide roll for heavy-duty chemical processing vats, we deliver exactly what your blueprint specifies.

  • Zero Material Waste: You only pay for the exact dimensions required for your application.

  • Rapid Deployment: Skip manual cutting and apply instantly on the assembly line.

  • Uniform Tolerances: Machine-slit edges guarantee a consistent, perfect seal every time.

The Advantage of One-Sided Acrylic PSA

To accelerate assembly and eliminate the mess of liquid adhesives, our Viton® sponge tape features a high-performance acrylic PSA protected by a quick-release liner.

  • High Initial Tack: Instantly bonds to metals, glass, and high-surface-energy plastics.

  • Long-Term Stability: Unlike standard rubber adhesives, acrylic PSA builds bond strength over time and resists degradation from thermal cycling and moisture.

Don't let inferior weatherstripping compromise your design.

Thermal & Environmental Resistance

Property Typical Value
Continuous Temperature Range -10°F to 400°F (-23°C to 204°C)
Intermittent High Temperature Up to 500°F (260°C)
Ozone Resistance Excellent
UV / Weathering Resistance Excellent
Fluid Resistance Excellent (Aliphatic/Aromatic Hydrocarbons, Oils, Acids)

Acrylic Pressure-Sensitive Adhesive (PSA) Properties

Property Typical Value Notes
Adhesive Type High-Tack Acrylic
Peel Adhesion (Stainless Steel) > 50 oz/in (13.7 N/25mm) PSTC-101
Adhesive Temperature Range Up to 300°F (149°C) Engineering Note: The acrylic PSA has a lower thermal threshold than the Viton® sponge. For applications exceeding 300°F, mechanical fastening may be required once the adhesive degrades.
