Unplasticized poly

Alkanesulfonates are widely used as an internal antistatic agent for poly(vinyl chloride) (PVC). Since alkanesulfonates cause hazing of unplasticized PVC in the normally used quantities of 1.0 to 1.5 parts per hundred parts resin (phr), its main use is in the manufacture of opaque PVC-calendered film. To produce transparent unplasticized articles, the addition of alkanesulfonates should not exceed 0.3 phr. Figure 40 shows the antistatic effect of alkanesulfonates in PVC. [Pg.209]

Table VIII lists some representative T0 values of unplasticized polymers. Very flexible polymers such as polyethylene, polyisoprene, polybutadiene, have low T0 values, whereas polymers with stiff backbone chains and bulky side groups, such as poly(methyl methacrylate) and polystyrene, have a high Tg. Clearly, it is a polymer with a high revalue where plasticization is most needed and where a significant lowering of Tg owing to the plasticizer may be expected.

Poly(vinyl chloride) films are produced in two main forms—unplasticized and plasticized—and over the years different machines have been manufactured to handle the two types. When calendering unplasticized PVC there is a tendency for small particles, usually referred to as crumbs , to fall away from the edges of the film and from the feed nip. Such crumbs then could fall on to the finished film, where they would stick and form defects. To avoid this, producers of unplasticized film usually prefer an L configuration in which the product travels up the stack and surface contamination of this kind is prevented. With plasticized PVC the problem of crumbs does not occur to any great extent and, as it is an advantage to have good access to the part of the calender where the finished film is made, an inverted L configuration is the most popular. [Pg.53]

Dispersions of vinyl acetate-ethylene copolymers have been used with success in bonding plasticized and unplasticized poly(vinyl chloride). [Pg.96]

Impact strength can be improved by other methods of modification—for example, by biaxial orientation of the material during or immediately after moulding. When transparent or translucent bottles are required in unplasticized poly(vinyl chloride) strength can be improved by including up to about 10% methyl-butadiene-styrene copolymers the bottles resulting retain a good finish. [Pg.141]

Improvements of clarity in transparent materials can be obtained in a variety of ways. If unplasticized poly(vinyl chloride) includes an impact modifier with refractive index matching that of the polymer it is possible to use thinner sections and so increase clarity, rates of output, and gloss. With polyolefins, similar results may be achieved by including a nucleating agent to accelerate crystallization even polypropylene, which normally is translucent, thus can be made in an almost clear form. [Pg.151]

Unplasticized poly(vinyl chloride) compositions can be extruded in transparent, translucent, or opaque forms—to give (as examples), film, flat or corrugated sheet, and profiles such as gutters, downpipes, and troughs. For uses such as pipework the extruded products may be fixed or joined with fittings injection moulded from the same or similar material. [Pg.159]

Extruder screws and the range of conditions available on a particular machine may be versatile enough for several materials and grades but if it is desired, say, to extrude polyamide 6.6 or an unplasticized poly(vinyl chloride) more consistent and satisfactory results can be obtained by fitting a dedicated screw designed specially for the material concerned. For polyamide 6.6, for example, the unit should be capable of generating higher temperatures than are needed for an amorphous thermoplastic. [Pg.164]

Poly(vinyl chloride) may be calendered in plasticized or unplasticized form and thin film can be produced by calendering followed by stretching (with stretch ratios of up to 8 1). Such products have a very wide range of uses. [Pg.171]

Inherently Stable Structure. Inherent stability of the polymer structure includes resins such as unplasticized poly (vinyl chloride) containing about 56% chlorine which is self-extinguishing and poly(vinylidene) chloride. [Pg.323]
