Extruder applications

Extruded applications of nylon, other than film and monofilcunent, are less commonly encountered because of the low melt viscosity of the polymers. Uses include cable sheathing which requires resistance to abrasion and/or chemical attack, flexible tubing for conveying petrol and other liquids, piping for chemical... 

Besides film, other extruded applications of nylons are as monofilaments, which have found applications in surgical sutures, brush tufting, wigs, sports equipment, braiding, outdoor upholstery, and angling. 

Liquid silicone rubbers have also been used in some extruded applications. Vulcanization of the extruded material may be carried out by using infrared heaters or circulated hot air. The process has been applied to wire coating, ignition cables, optical fibers, various tapes, and braided glass-fiber sleeving, as well as for covering delicate products. 

The high-torque drives that are just now emerging hold lots of technically and economically promising options for extruder applications in the years to come the first few high-speed extruders with high-torque drives are already on the market - for plastics. 

Large volume opaque rPVC applications include pipe, siding, lineals and pipe fittings. In general the cost of the formulation increases in that order. The first three are extruded applications, while pipe fittings are injection molded. A typical siding formulation consists of ... 

In-process wire and cable insulation is recovered and can be used in other multilayer-extruded applications garden hose is a common example. This is feasible because in-process wire is generally stripped of insulation rather than chopped. On the other hand, postconsumer wire is generally sent to rendering... 

ABS has an improved impact resistance and toughness over polystyrene and also superior chemical resistance. It can be injection moulded, blow moulded and extruded. Applications in food packaging include injection moulded cake and bread trays and margarine tubs.
