How to Compare Barrier Screws | Plastics Technology
Screw designers are constantly asked to improve output quantity without sacing quality—or to improve both at the same time. Barrier-type feed screws are the most widely used designs in high-output, high-quality extrusion. In applications that also require low melt temperature, such as blown film, they are the standard.
