K-FLEX SEALING TAPES
are engineered to complement our world-class elastomeric insulation, ensuring every installation is airtight, energy-efficient, and durable. Whether you are managing moisture in high-humidity environments or protecting outdoor assets from the elements, our specialized tapes provide the professional seal your project demands.
K-FLEX® ST ANTI-CONDENSATION TAPE
K-FLEX ST Anti-Condensation Tape is a high-performance, self-adhesive insulation solution designed to prevent moisture buildup and energy loss in demanding environments. Made from highly flexible closed-cell elastomeric foam (FEF), it provides a built-in vapour barrier that eliminates the need for additional protective layers
Key Benefits & Features
- Superior Condensation Control & Efficiency: Features high water vapour resistance (>7000) and low thermal conductivity (0.033 at 0°C), preventing condensation and conserving energy.
- Safety & Durability: Offers Euroclass B-s3, d0 or Class 0 fire ratings, with a dust, fibre, mould-resistant, antimicrobial, and chemically resistant composition.
- Easy Application: Features a strong, pressure-sensitive adhesive ideal for sealing joints, seams, and complex pipe fittings.
Technical Specifications
- Material: Closed-cell NBR foam, typically 3mm thick.
- Performance Range: Suitable for temperatures from -40°C to +85°C.
- Dimensions: Available in 3mm (thick) x 50mm (wide) x 9m (long) rolls.
- Corrosion Resistance: pH Neutral.
Common Applications
- HVAC & Plumbing: Ideal for sealing all insulated chilled water lines, insulated refrigeration pipes, and insulated cold water ducts.
- Specialized Environments: Suitable for clean rooms, hospitals, and residential projects due to its hygiene-friendly, fibre-free nature.
K-FLEX® AL CLAD SEALING TAPE
K-FLEX AL-CLAD Sealing Tape is a premium, multi-layered self-adhesive jacketing and sealing tape specifically designed for both indoor and outdoor insulation protection. Unlike standard foil tapes, the AL-CLAD system features a robust, PVC-aluminium covering that provides a durable, shock-resistant finish that can regain its shape even after mechanical pressure.
Key Benefits & Features
- Weather & UV Resistance: Engineered for outdoor longevity, the AL-CLAD foil offers approximately 11 years of UV stability and acts as a waterproof barrier against harsh atmospheric agents.
- Chemical & Corrosion Protection: The surface is highly resistant to aggressive chemicals, including various acids, salts, and petroleum.
- High-Efficiency Seal: With an exceptionally low vapour permeability (0.052g/m²/d), it prevents moisture ingress and eliminates thermal bridges.
- Mechanical Strength: It is designed to be puncture-resistant and robust, protecting underlying insulation from physical abuse and crushing during handling.
Technical Specifications
- Temperature Range: Suitable for temperatures from up to.
- Total Thickness: Approximately 0.28mm (+-0.05mm).
- Tensile Strength: High longitudinal and transverse resistance (approx. 175N/15 mm).
- Fire Rating: Typically achieves Euroclass CL-s3, d0 (for pipes) and Class 0 ratings when used on the K-FLEX AL-CLAD System.
Common Applications
- HVAC/R: Essential for sealing joints and seams on ventilation ducts and large refrigeration pipes to maintain airtight integrity.
- Industrial Plants: Protection for outdoor piping in oil, gas, and marine environments where saltwater and weather exposure are common.
- Complex Geometries: Its high flexibility allows it to adapt to awkward shapes, elbows, and “T” connections without losing its protective seal.
