Kingflex Kingflex

China isolation pipe 1/4" ID Factory, Quotes

Kingflex is the fiber-free, flexible, elastomeric pipe insulation for reliable protection against condensation, mold, energy loss and ultraviolet radiation in residential and commercial applications. The closed-cell nature of elastomeric foam insulation provides superior protection against thermal losses, condensation and moisture accumulation that leads to mold. It is the ideal choice for insulating mechanical piping systems.

Rubber Foam Insulation Structure

Application & Performance Integrity

Rubber Foam Insulation could be used in schools, hospitals, government institutions and commercial spaces of all types value the long-term performance. Its moisture-resistant characteristics make it especially valuable on chilled-water and refrigeration piping where condensation might otherwise soak through fibrous types of insulations, significantly degrading their thermal performance, leaving them susceptible to fungal growth and ultimately shortening their life cycle. Moisture-resistant rubber foam insulation, however, maintains its physical and thermal integrity -- for the life of the mechanical system!

Frequently Asked Questions
Q:What are the main advantages of using a closed-cell structure for insulation?
The closed-cell structure provides exceptional control against condensation and prevents energy loss, ensuring long-term thermal efficiency in mechanical systems.
Q:Does this rubber foam insulation require an additional vapor retarder?
No. It features a built-in vapor barrier that completely eliminates the need for additional vapor retarders, simplifying the installation process.
Q:What sizes and wall thicknesses are available for installation?
It comes in nominal wall thicknesses ranging from 1/4” up to 2” (6mm to 50mm) and standard lengths of either 6ft (1.83m) or 6.2ft (2m) to support a complete size range for HVAC/R systems.
Q:What is the operational temperature range and fire safety rating of this material?
The material operates safely within a temperature range of -50°C to 110°C. It meets the Class 0 & Class 1 fire rating standard under BS 476 Part 6 & 7.
Q:Why is rubber foam preferred over fibrous insulation on chilled-water piping?
Fibrous insulation can soak through when condensation occurs, leading to performance degradation and fungal growth. Our moisture-resistant rubber foam retains its structural and thermal integrity for the life of the mechanical system.
Q:Does this insulation material withstand outdoor conditions?
Yes, the technical data shows it has good resistance to ultraviolet (UV) radiation, ozone, and weathering, effectively retarding environmental degradation.
