High Temperature PTFE Heated Hose with Non-Stick Melt Bore & Uniform Heating for Extruder Barrel-to-Die Connections

The connection between extruder barrel and die works harder than almost any other fitting on the line: it carries molten polymer, absorbs machine vibration, survives thermal cycling, and must flex for installation and alignment. This Heated Hose is built for that job on plastic extruders and melt transfer systems, replacing rigid links with a flexible, heat-holding connection that protects both product quality and tooling. Working as an electrically heated hose for temperature-controlled melt transfer, it serves extrusion lines, scribing machines, and compounding equipment across the polymer processing industry.

Polymer melt flows through a non-stick PTFE bore whose slick, corrosion-resistant interior neither adheres to the media nor lets degraded material linger—supporting faster color and compound changeovers with less contamination risk between runs. A uniform heating element wraps the full hose length, delivering thermal stability with no cool sections at the joint where melt condition could drift, while a high-pressure-enduring reinforced body carries line pressure with margin. The flexible construction absorbs vibration that would otherwise stress dies and adapters, and the insulated cover keeps heat in and surface temperatures manageable beside the line.
