The second edition of Extrusion is designed to aid operators, engineers, and managers in extrusion processing in quickly answering practical day-to-day questions. The first part of the book provides the fundamental principles, for operators and engineers, of polymeric materials extrusion processing in single and twin screw extruders.
For example, in a coextruded sheet of GPPS and HIPS, or styrene–acrylonitrile (SAN) and acrylonitrile–butadiene–styrene copolymer (ABS), the scrap may be extruded back into the rubber-modified layer as a mixed polymer blend.
The dilution of the rubber-modified phase with unmodified skin-layer polymer may cause some loss in impact strength Cited by: A coextrusion system is a combination of parts which takes molten polymer from two or more extruders, routes and shapes the melt and delivers it to the combination point where the melts are stacked and then delivered to a die for spreading to the final width ().In its most general configuration, the coextrusion system Equipment and polymer selection for coextruded sheeting.

Today more development time is probably connected with selecting the best polymer for an application through pilot coextrusion runs. A feedblock is made with openings for each layer in a coextruded structure.
Consider the simulated feedblock shown in Figure ; there are three openings in which up to three different polymer melts can be number of extruders and different melt configurations depend on the application and the coextrusion objective.

They are a cost-effective, space-age replacement for conventional plywood panels that are often used once and then discarded. Polymer manufacturing processes can be divided into continuous processes and batch processes.
In continuous process where raw material is fed in continuously and the product flow appears continuously e.g. extrusion, there is more efficient use of energy and it is easier to maintain a consistent quality. Int. Mech. Eng. & Rob. Res.

U.S. Pat. 4, describes a coextruded sheet structure of 25 to mils, the surface layer of the sheet structure being 3 to mils of AES graft polymer. The total thickness of the sheet precludes the sheet from being used in applications where thin films (generally less than 25 mils and preferably less than 10 mils) are used.
