Electrically Heated PTFE Hose with Ratio-Stable Temperature & Non-Stick Interior for Polyurethane Metering Systems

In polyurethane processing, the defects that cost the most are the ones nobody catches until the end—delaminated panels, collapsed foam, scrapped parts that trace back to a feed line that drifted a few degrees upstream. This Heated Hose is engineered for polyurethane metering systems and laminating production lines, 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 first-pass yield across continuous production operations.

Each component flows through a non-stick PTFE interior whose slick surface resists pre-cure buildup—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.
