The Green Roller is an equally exciting new development but for different reasons. It is a high quality sleeve that is highly suitable for the majority of roller positions outside of the initial lead out area (hot zone). They are designed to take the hot extrusion from the Gold Roller at a suitable point determined from experience on each system.
The Green Roller is woven from a high temperature blend of aramid and pan/carbon fibres. They have excellent resistance to abrasion and physical distortion caused by heat and pressure. Their operating contact temperature is around 500ēC making them ideally suitable for most roller positions along the run out system.
A light impregnation of inorganic, environmentally benign, solution capable of withstanding temperatures well in excess of 600ēC completes the manufacture of both the Gold and Green Rollers . All the standard diameters are available in any specific length you may need. The nominal wall thickness is 5mm.
