  • CPVC PIPE WITH 25% HIGHER HYDROSTATIC DESIGN BASIS THAN REQUIRED UNDER ASTM D2846
    Publication number: 20150284554
    Abstract: CPVC pipe in diameters in the range from 15 mm (0.5 inch) to 15.24 cm (6 ins), to carry hot and cold aqueous streams under 690 KPa (100 psi) pressure and 82.2° C. (180° F.) in continuous service, is extruded from a compound in which the CPVC has a high Cl content in the range from 66.5%-70%, when modified with either of two specific impact high rubber modifiers in an amount greater than 5 parts but no more than 6 parts per 100 parts of CPVC. Extruded CPVC pipe provides a HDB measured according to ASTM D2837-01 which is 25% or more greater than that required for commercial pipe as specified in ASTM D2846. As a result, both SDR-11 and SDR-13.5 pipe are produced which provide a HDB of at least 1250 psi (8.62 MPa) at the 100,000 hr intercept.

  • CPVC compositions having good impact strength and heat stability, and smooth surfaces
    Patent number: 7928169
    Abstract: A CPVC composition having good impact and heat stability includes a siloxane-acrylic copolymer impact modifier and an aluminosilicate zeolite, and a reduced amount of a liquid stabilizer such as a tin compound. Such compositions can be formed into piping for indoor and outdoor water systems including hot water.
