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.

Viton® Sponge (Elastomer) Properties
| Property | Typical Value | Test Method / Standard |
| Polymer Base | Fluoroelastomer (FKM) | N/A |
| Cell Structure | Closed-Cell | N/A |
| Density | 17 – 19 lbs/ft³ (272 – 304 kg/m³) | ASTM D1056 |
| Compression Deflection (25%) | 6.5 – 5.5 psi | ASTM D1056 |
| Tensile Strength | 146 psi | ASTM D412 |
| Elongation at Break | 343% | ASTM D412 |

| Compression Set (22 hrs @ 75°F) | 13-27% | ASTM D395 |
| Flammability | Self-Extinguishing | FMVSS-302 / UL 94 |
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. |
