Elastomeric Insulation
Elastomeric Pipe Insulation | K-FLEX ST & ST/SK
Elastomeric insulation is a premium closed-cell rubber insulation designed for HVAC, refrigeration, and chilled water systems. K-FLEX elastomeric products deliver superior thermal performance, moisture resistance, and long-term durability in demanding applications.
Why Choose Elastomeric Insulation?
Superior Moisture Resistance
Closed-cell elastomeric structure provides exceptional water vapour resistance (μ ≥ 7,000), preventing condensation and maintaining thermal efficiency over the product lifetime.
Excellent Thermal Performance
Low thermal conductivity (λ₄₀ = 0.036 W/m·K) ensures effective insulation across a wide temperature range from -165°C to +110°C, ideal for both refrigeration and heating applications.
Flexible & Easy to Install
Flexible rubber construction allows for easy handling around bends, fittings, and complex pipework. Available in pre-slit tube format for fast installation.
Fire Safety Certified
K-FLEX ST achieves Euroclass BL-s2,d0 fire rating, meeting stringent building regulations for commercial and industrial installations.
Long Service Life
Resistant to UV degradation, ozone, and chemical exposure. Maintains performance for decades without deterioration or loss of insulation value.
