HF Tube

All Kingflex elastomeric insulations are engineered and manufactured for HVAC and other industrial applications. With closed cell structure Kingflex insulations effectively retard heat flow and prevent condensation when properly installed. The environmental friendly materials are manufactured without the use of CFC’s, HFC’s or HCFC’s. They are also formaldehyde free, low VOCs, fiber free, dust free and resistant to mold and mildew.

Kingflex HF Tube contains no chlorides, fluorides, bromides or PVC. It is specially formulated for thermal efficiency and condensation control in marine and offshore environment that require specific protection against smoke containing acid gases. 
Kingflex HF Tube remains flexible at temperatures from -297℉(-183℃) to +300℉ (+150℃) with intermittent exposure to +350℉(+175℃). Kingflex HF provides exceptional ozone and ultraviolet resistance.

Kingflex HF Tube provides low thermal conductivity, good fire behavior, low temperature flexibility, and excellent protection against heat flow and water vapor diffusion.
