Description

Durable, Safe and Versatile Sealing for Industry, Chemical and Pharmaceutical Use

Uniflexon sealing tape is made from 100% expanded PTFE (ePTFE), offering exceptional chemical resistance, flexibility and mechanical strength. With its self-adhesive backing, it is easy to install on flanges and joints of various materials – even in complex or hard-to-reach configurations.

Technical Specifications

Temperature range: –200 °C to +260 °C (continuous)
Pressure resistance: Up to 80 bar
pH range: Chemically inert (0–14)
Tensile strength: 4 MPa
Shore hardness: 55–65 ShA
Friction coefficient: 0.1–0.2 (ISO 8295)
Density: 0.65–0.85 g/cm³ (ASTM D792)
Compressibility / recovery: 60% / 10% (ASTM F36A)
Gas sealability: 0.1 ml/h at 40 bar (ASTM F37)
Flame resistance: UL 94 V-0
Compliance: FDA 21 CFR 177.1550, EC 10/2011, ASME

Key Benefits

Universal chemical resistance against acids, alkalis, solvents and aging.
Soft, elastic and strong, ideal for fragile surfaces like glass, ceramics or plastics.
Perfect fit due to lateral expansion and easy cutting.
Self-adhesive backing enables fast, clean installation without waste.
Unlimited shelf life – no degradation over time.

Applications

Light flange connections
Equipment in the chemical, food, and pharmaceutical industries
Fragile sealing surfaces (e.g., plastic or epoxy)
Maintenance-critical and temporary seals

Available Versions

Profiles: Rectangular, square, and round
Sizes: From 3x mm to 85 mm width
Packaging: Individual rolls in boxes or palletised bulk sets

Installation Tip

Select tape width approx. 1/2 to 2/3 of the flange width to allow for lateral expansion during compression.

Frequently asked questions

Up to what temperature is ePTFE sealing tape resistant?

Up to 260 °C. The Uniflexon UFX tape is available in widths from 10 to 20 mm, thicknesses from 3 to 7 mm and roll lengths from 8 to 17 metres.

How do I apply the sealing tape?

The tape has a self-adhesive layer and is applied across the full sealing zone. The technical datasheet and the fitting instructions are available as downloads on the product pages.

Why ePTFE instead of a cut gasket?

One roll of tape covers a wide range of flange sizes: you cut the length you need and the flexible ePTFE moulds itself to the sealing zone. That saves stock and custom cutting.
