Flexible PTFE Heated Hose with Corrosion Resistant Bore & High Flexibility for PU Foam & Laminating Lines

In polyurethane processing, the most expensive defects are the ones traced back too late—collapsed foam, delaminated panels, scrapped parts that began with a feed line drifting a few degrees upstream. This Heated Hose is engineered for polyurethane processing equipment and metering systems, carrying polyol and isocyanate components at a ratio-stable temperature from the metering unit to the mixing head. Working as an electrically heated hose for temperature-controlled component transfer, it protects foam cell structure, laminate bond strength, and production yield across continuous operations.

Each component flows through a pre-cure resistant PTFE interior whose non-stick surface refuses to let early-curing polyurethane take hold—keeping lines cleaner between runs and shortening changeovers when switching products. A uniform heating element wraps the full hose length, delivering ratio-stable temperature with no cool sections where viscosity could drift and tilt the mix, while the corrosion-resistant bore withstands the chemistry of both components over a long service life. The high-flexibility construction follows dispensing heads and moving machine parts without kinking, and the insulated cover keeps heat in through long production cycles.
