China isolation pipe 1/4" ID Manufacturers, Factory

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.

Insulation Application Performance

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 insulation, however, maintains its physical and thermal integrity -- for the life of the mechanical system!
