New resin for pipes and water mains
The improvements in mechanical properties - creep (cold deformation under load), impact strength and rapid crack propagation - ensure that the new resin will meet all of the required standards in this segment (ISO, DIN, EN and NBR). "In addition to PAC2, the growing demand for this specific type of resin is also being driven by the federal government's program to promote universal access to basic sanitation, which seeks to improve public health conditions by reducing the country's deficit in water and sewerage services," explained Marcos Celestino, an application engineer at Braskem.
The resin's main uses include pipes for water and natural gas distribution networks, pipelines to transport ore slurry and oil, sewage networks and water mains. In addition to the water and sewerage utilities (Sabesp in the state of São Paulo, DMAE in Rio Grande do Sul and Copasa in Minas Gerais), the end-users of the materials include companies like Vale, Petrobras and Odebrecht. Braskem's main clients using the resin to make pipes are Tigre, FGS, Kanaflex, Majestic and Polierg.
