K-FLEX ST
Rubber flexible technical insulation, which is ideal for surfaces with both positive and negative temperatures. Its versatility allows it to be used on pipelines, ducts, and other equipment in HVAC systems.
Purpose and application areas:
- Air conditioning systems: Insulation for refrigerant lines, chiller pipelines, fan coils. It prevents cold loss and condensation, which is critical for efficiency and preventing damage to system components and building structures.
- Refrigeration systems: Protection of pipelines and equipment in cold rooms, display cases, industrial refrigerators. It maintains a stable low temperature, reducing the load on compressors.
- Ventilation systems: Insulation of round and rectangular ducts to maintain the temperature of the supplied air and prevent condensation on their surface.
- Heating and water supply systems: Minimizes heat loss in hot pipelines and prevents freezing in cold ones.
- Industrial applications: From pipelines to cryogenic systems (after consultation with the technical department).
Key technical characteristics of K-FLEX ST:
| Indicator | Value | |
|---|---|---|
| Application temperature | from -165°C to +110°C* (for tubes), up to +90°С (for sheets). * For industrial applications, use up to -198°C is allowed (after consultation with the technical department). | |
| Thermal conductivity coefficient, W/(m•K) (according to GOST 16381-77, p.2.2) | Thicknesses ≤ 25 mm:
– 20°С = 0.031; 0°С = 0.033; +20°С = 0.035; +40°С = 0.037. |
Thicknesses > 25 mm:
– 20°С = 0.034; 0°С = 0.036; +20°С = 0.038; +40°С = 0.040 |
| Water vapor diffusion resistance (μ factor) (according to EN 12086 (DIN 52615)) | ≥ 10,000 (a critically important indicator for preventing condensation in cooling and air conditioning systems) | |
| pH value (according to EN 13468) | Neutral (7±1) | |
| Environmental safety | Asbestos-free / CFC-HCFC-free (does not destroy the ozone layer – important for HVAC environmental standards) | |
| Resistance to oil and gasoline | Good | |
| Biological resistance | Good (prevents the growth of fungi and mold – important for air quality and hygiene in ventilation systems) | |
| Odor | Neutral | |
| Fire safety | G1 - DSTU B V.2.7-19-95 (GOST 30244-94) (important for building safety) | |
| Color | Black | |
| Covering (for sheets) | KRAFT (foil, aluminum sputtering) / ALU (aluminum) | |
| Compatibility systems | AL CLAD / IN CLAD / IC CLAD / COLOR UV / K-FONIK (possibility of integration into complex K-FLEX solutions) | |
Advantages of K-FLEX ST for HVAC:
- Reliable protection against condensation: Thanks to its high water vapor diffusion resistance, K-FLEX ST effectively prevents condensation on cold surfaces, protecting equipment from corrosion and extending its service life.
- Maximum energy savings: Minimizes cold or heat loss, leading to significant energy savings and reduced operating costs.
- Flexibility and ease of installation: The elasticity of the material allows it to be easily mounted on complex-shaped pipes, speeding up the work process.
- Durability and resistance: The material does not rot, is not affected by fungi, mold, and most chemicals, which ensures stable system operation for decades.
- Fire safety: Low flammability complies with building safety requirements.
