K-FLEX ST
K-FLEX ST is a high-performance, closed-cell NBR [Nitrile Butadiene Rubber] elastomeric lagging foam designed for versatile thermal and acoustic insulation in both civil and industrial applications. It is widely used to prevent condensation and improve energy efficiency in systems ranging from refrigeration and air conditioning to heating and plumbing.
Key Benefits & Features:
- Thermal Performance: Offers very low thermal conductivity (0°C = 0.032 W/(m·K)), making it a primary choice for long-term energy conservation.
- Built-in Vapour Barrier: The high-density closed-cell structure provides high resistance to water vapour diffusion, eliminating the need for additional vapour barriers.
- Fire Safety: Features a Class “0” fire rating and meets Euroclass standards (BL-s2,d0 for pipes; B-s3,d0 for sheets), ensuring safety in diverse building environments.
- Hygiene & Durability: The material is dust- and fibre-free, antimicrobial, and resistant to mould, fungi, and chemicals.
- Extreme Temperature Range: Suitable for a wide range of applications, maintaining flexibility and performance from -165°C to +110°C.
Common Applications:
- HVAC Systems: Insulation for ductwork and chilled water lines.
- Refrigeration: Protection for refrigeration pipework and industrial cooling systems.
- Industrial Tanks: Thermal management for large pipes, tanks, and fittings.
- Sensitive Environments: Ideal for apartments, hospitals, and clean rooms due to its fibre-free composition.
Available Formats & Custom Options:
We stock K-FLEX ST in multiple configurations to suit both new installations and retrofitting projects:
- 100cm Wide Sheets: The standard for insulating large surfaces, tanks, and ductwork.
- 100cm Wide Self-Adhesive Sheets: Features a pressure-sensitive adhesive backing for significantly faster installation without the need for manual glue application.
- 2m Unslitted Pipe Sections: Ideal for new installations where the insulation can be slid over pipes before they are connected or cut and glued over existing pipes.
- ST Sealing Tape – Ideal for sealing seams or covering neatly over joints. 3mm x 50mm x 9m Self-Adhesive Rolls.
- Custom Order Only – 150cm Wide Sheets: Extra-wide sheeting available for large-scale industrial projects requiring fewer seams.
- Custom Order Only – 2m Pre-slitted Self-Adhesive Pipe Sections: Designed for rapid retrofitting on existing pipework; simply snap over the pipe and seal with the integrated adhesive strip.
Our tubes and sheets can be manufactured with specialized protective layers or cladding:
- Aluminium cladding: Provides a high-performance 4-layer laminate for superior mechanical protection and a professional aesthetic finish.
- UV & Impact Resistant Plastic Cladding [Tubes Only]: A factory-applied protective layer that increases resistance to UV rays, mechanical abuse, and chemical exposure.
