High Temperature PTFE Non-Adhesive Heated Hose with Uniform Heating & Ratio-Stable Temperature for PU Processing Lines

In polyurethane processing, a few degrees of drift in the feed line can shift viscosities, upset the mix ratio, and show up as weak bonds or inconsistent foam. This Heated Hose is engineered for PU processing lines and laminating machines, 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 reaction timing and product consistency across foam production, bonding, and coating operations.

Each component flows through a non-adhesive PTFE bore whose slick surface resists pre-cure buildup—keeping lines cleaner, flow more accurate, and changeovers faster between runs. A uniform heating element wraps the full hose length, delivering consistent warmth with no cool sections where viscosity could drift, while the flexible construction follows dispensing heads and machine movement without kinking. The insulated cover retains heat and shields adjacent components, and the corrosion-resistant interior stands up to the chemistry of both PU components over long service life.
