CPVC sprinkler pipe inside a firestop mock-up. Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses include hot and cold water delivery pipes and industrial liquid handling.
The Cradle to Cradle Products Innovation Institute (C2CPII) is a non-profit group that develops and administers the Cradle-to-Cradle Certified Product Standard. This multi-attribute standard evaluates a product's performance in five impact categories: material health, material reutilization, renewable energy and carbon management, water stewardship, and social fairness.
Rigid PVC is used in construction for pipes, doors and windows. It is also used in making plastic bottles, packaging, and bank or membership cards. Adding plasticizers makes PVC softer and more flexible. It is used in plumbing, electrical cable insulation, flooring, signage, phonograph records, inflatable products, and in rubber substitutes.

Basic insulation is any material added to protect a user from accidental contact with energized parts. Supplemental insulation is rated to withstand 1500 volts AC. Double insulation is a design concept where failure of one insulation system will not expose the user to a shock hazard due to the presence of a second independent layer of insulation.
Insulated hot water supply and return hydronic piping on a gas-fired boiler. Since pipework can operate at temperatures far removed from the ambient temperature, and the rate of heat flow from a pipe is related to the temperature differential between the pipe and the surrounding ambient air, heat flow from pipework can be considerable.
The bodies of fittings for pipe and tubing are often the same base material as the pipe or tubing connected: copper, steel, PVC, CPVC, or ABS. Any material permitted by the plumbing, health, or building code (as applicable) may be used, but it must be compatible with the other materials in the system, the fluids being transported, and the ...
Do you find yourself wandering the aisles of a grocery store unsure of what food products are truly good for you and what's marketing hype? It's common to see "natural," "whole grain" and "organic ...
The Comparative Tracking Index (CTI) is used to measure the electrical breakdown (tracking) properties of an insulating material.Tracking is an electrical breakdown on the surface of an insulating material wherein an initial exposure to electrical arcing heat carbonizes the material.
