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

In polyurethane processing, the most expensive quality problems are the ones nobody sees until the end—foam that collapsed, bonds that failed, parts that scrapped out because a feed line drifted a few degrees upstream. This Heated Hose is engineered for polyurethane metering systems and foam 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 first-pass yield across continuous laminating, dispensing, and foam 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.
