RAW MATERIALS AND APPLICATIONS Development of Compositions for the Production of Fiberglass Pipes based on unsaturated Poly esters obtained from Pet Waste

The technological properties of unsaturated polyesters synthesized on the base of products from alcoholysis of secondary polyethylene terephthalate, which meets the requirements of the technology for the production of polymer composite and fiberglass pipes, are studied.

Underground communications are aging all over the world. Millions of water and sewer pipes need reconstructing. It is a global problem in nature. In most cases, the cause of the problem is corrosion. The internal unprotected surface of concrete sewage header is quickly destroyed by the action of sulfuric acid, which is formed during the oxidation of hydrogen sulfide.
