Chlorinated Polyvinyl Chloride CPVC

An ASTM specification, ASTM F493, covers solvent cements for CPVC pipes and fittings. No particular solvent system is specified, but solvent systems consisting of blends of tetrahydrofuran and cyclohexanone are suggested. A minimum of 10% CPVC resin is required for bodying. [Pg.227]

When acetylene and hydrochloric acid are reacted to produce polyvinyl chloride, the chlorination is approximately 56.8%. Further chlorination of [Pg.129]

PVC to approximately 67% produces CPVC whose chemical structure is [Pg.130]

While PVC is limited to a maximum operating temperature of 140°F (60°C), CPVC has a maximum operating temperature of 190°F (82°C). There are special formulations of CPVC that permit operating temperatures of 200°F (93°C). [Pg.130]

There are many similarities in the chemical resistance of CPVC and PVC. However, care must be exercised because there are differences. Overall, the corrosion resistance of CPVC is somewhat inferior to that of PVC. In general, PVC is inert to most mineral acids, bases, salts, and paraffinic hydrocarbons. [Pg.130]

CVPC is not recommended for use with most polar organic materials including various solvents, chlorinated or aromatic hydrocarbons, esters, and ketones. [Pg.130]

Polyvinyl chloride Polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC) pipe and tubing are available in sizes 12 in and smaller for PVC and 4 in and smaller for CPVC. They have excellent resistance at room temperature to salts, ammonium hydroxide, and sulfuric, nitric, acetic, and hydrochloric acid but may be damaged by ketones, aromatics, and some chlorinated hydrocarbons.

There are three broad classifications for rigid PVC compounds Type II, chlorinated polyvinyl chloride (CPVC), and Type I. Type II differs from Type I due to greater impact values, but lower chemical resistance. CPVC has greater high temperature resistance. These materials are considered unplasticized, because they are less flexible than the plasticized formulations. PVC has a broad range of applications from high volume construction related products to simple electric wire insulation and coatings. CAS numbers are 9002-86-2, 8063-94-3, 51248-43-2, and 93050-82-9.

Chlorinated polyvinyl chloride (CPVC) possess excellent high-temperature performance and other desirable properties. Typical CPVC has about 57% chlorine and is prepared by chlorination of PVC. It has outstanding flame and smoke properties, chemical inertness, and low sensitivity to hydrocarbon feedstocks. The glass transition temperatnre of the polymer, Tg, increases with increase in chlorine content in the polymer. [Pg.171]

Chlorinated Polyvinyl Chloride. As implied by its name, chlorinated polyvinyl chloride (CPVC) is a chemical modification of PVC. CPVC has properties very similar to PVC but the extra chlorine in its structure extends its temperature limitation by about 50°F (28°C), to nearly 200°F (93°C) for pressure uses and about 210°F (99°C) for nonpressure applications. ASTM D 1784, the rigid PVC materials specification, also covers CPVC which it classifies as Class 23477-B. By the older designation system, it is known as Type IV, Grade 1 PVC. CPVCs for pressure pipe are designated CPVC 4120 [i.e.. Type IV, Grade 1 CPVC with a maximum recommended hydrostatic design stress of 2000 Ib/in (13.8 MPa) for water at 73.4°F (23°C)]. At 180°F (82°C) the maximum recommended hydrostatic design stress for CPVC is 500 Ib/in (3.4 MPa). [Pg.748]

Chlorinated polyvinyl chloride (CPVC) is a direct derivative of polyvinyl chloride (PVC) materials. CPVC materials are made by reacting chlorine with PVC in a secondary reaction process after PVC polymerization (postpolymerization). The chlorine content by weight of CPVC is increased by this addition of chlorine. Homopolymer PVC grades typically contain 56% chlorine by weight. CPVC contains about 67% chlorine by weight. CPVC materials offer a higher temperature service range. The increase in chlorine content increases the heat deflection temperature at 264 psi from 155°F (68°C) to 218°F (103°C). The chemical resistance of CPVC is similar to or better than that of PVC. [Pg.699]

Chlorinated polyvinyl chloride (CPVC) is more highly chlorinated than PVC. CPVC is commonly used for chemical or corrosive services and hot water above 140°F and up to 210°F. CPVC is commercially available in sizes of % inch to 12 inch for Schedule 40 and Schedule 80. Exposed CPVC piping should not be pneumatically tested, at any pressure, due to the possibility of personal injury from fragments in the event of pipe failure. [Pg.84]
