PUR (polyurethane reactive) hot melt adhesives are rapidly replacing conventional hot melts in woodworking, packaging, electronics, and automotive assembly—but they demand more from the delivery hose. Running at higher temperatures and extremely sensitive to fluctuation, PUR requires heated hoses with precise ±1–2°C end-to-end control, non-stick PTFE inner tubes, fast heat-up, and properly rated fittings. This article explains what makes PUR harder on hoses, what a PUR-ready hose needs, and why upgrading adhesive means upgrading your hose. We offer customizable electrically heated hoses and temperature controllers—share your adhesive datasheet for a tailored recommendation. Read More
