, low-odor, low-smoke compounds contain neither fillers nor abrasives, which reportedly makes them particularly well suited to cleaning hot-runner systems, regardless of gate size.

In fact, the newest members of this line, grades G315 and G320, are designed specifically for injection machines and hot runners A hot runner is an injection mold component containing a series of channels that distributes molten plastic within a mold to increase molding productivity through reduced waste, as the runners arent wasted each cycle by being ejected, as the plasic stays molten and gets used on the . G315 is tailored for purging polyolefins and has an operating temperature range of 338 to 599 F. Typical use level would range from 18 lb for a 60-mm screw to 46 lb for a 160-mm screw. G320 is recommended for purging a wide range of engineering thermoplastics as well as polyolefins. It can handle operating temperatures of 356 to 606 F and is specially adapted for cleaning large machines. Expected usage rate ranges from 3 lb for a 60-mm screw to 33 lb for a 140-mm screw.
