Polyvinyl chloride extrusion

The bowing of polyvinyl chloride extrusions caused by differential thermal shrinkage associated with different cooling rates was modelled. The extrusion was considered to consist of a number of rectangular sections, and a graphical solution for the differential equations for... [Pg.99]

Polyvinyl Chloride. (Table 15.5) this is the most versatile of the commercial thermoplastic polymers. It is used mainly for rigid and flexible plastics, for rubberlike products, for coatings on steel, cloth, and paper, and in smaller amounts for specialty fibers. It is processed mainly by extrusion and calendering, and in smaller amounts by injection, compression, and... [Pg.644]

At times, low- or high-intensity blending alone can produce a suitable product for use by the fabricator. An example of this would be a polyvinyl chloride (PVC) blend used for several large-volume extrusion applications. More frequently, however, a compounding process is required to obtain the desired physical property. The five primary compounding processes used in the industry for controlling the above parameters are single-screw extrusion (SSE), twin-screw extrusion (TSE), continuous mixers, batch mixers, and kneaders. Table 18.1 summarizes key aspects of each process. [Pg.269]

Butyl benzyl phthalate is a plasticizer added to polymers to give flexibility and softness. It is used extensively in polyvinyl chloride and in cellulose plastics, polyvinyl acetate, polysulfides, and polyurethane. Also used in flexographic inks for food packaging applications and acrylic coatings, profile extrusions, slush moulding, film and sheeting, coated fabrics, floor and wall coverings, vinyl foams and plastisols for car sealants. [Pg.296]

The general purpose thermoplastics introduced in the 1930 s and 1940 s were readily fabricated by extrusion and injection molding techniques. Thermoplastics, such as polyvinyl chloride, polystyrene and polyethylene were resistant to mineral acids at temperatures up to 60OC but they could not be used at higher temperatures, such as that of boiling water. These large volume plastics had other characteristic deficiencies which were overcome by the use of additives. [Pg.88]

There are some other ways to apply coatings without the use of solvents. Plastisols315 involve the use of a paste of polyvinyl chloride particles in a plasticizer. Metal objects dipped in this can then be heated to harden the coating by dissolution of the plasticizer into the polymer. An example would be a wire rack for a dishwasher. Colored paint films can be laminated to plastics such as automobile parts and siding for houses by molding.316 Ideally, the dry paint film would be prepared by extrusion or other means that avoided the use of solvent. It is also possible to produce a coating from two monomer ingredients that polymerize in... [Pg.226]
