Moscow -- Dow Chemical Co. says its Russian polyurethanes business is involved in a number of projects to help develop reliable and modern infrastructure in the city of Sochi and the Krasnodar region.
Insulation materials - based on polyurethane systems produced at the Dow Izolan manufacturing facility in Vladimir - have been used to replace old pipes and build pipelines of the heating system for sports and Olympic venues in Sochi. Other uses are in a series of infrastructure projects in the coastal and mountain areas, as well as in the Cathedral of the Christ Nativity, the First City Hospital and Drama Theatre in Krasnodar.
Dow says the Izolan plant, built in 2009, is among the group's safest and most competitive blending facilities for polyurethane systems in the world. The plant can call on Dow's 60 years of experience in formulating PU systems, as well as on Izolan's own capabilities, market and local customer knowledge.
"Izolan 350 systems, used for pipes insulation in Sochi and Krasnodar, passed the MPA Hannover certification of conformance with European Quality Standard EN 253," said Gennady Vaskov, commercial manager for rigid polyurethane foams at Dow Izolan, in a company statement.
"These systems were developed to meet the requirements of Montreal Protocol and ensure the product does not contain any ozone-depleting blowing agents. Dow Izolan formulated systems are supplied to most manufacturers of insulated, foam polyurethane pipes in Russia and the CIS," Vaskov added.
Pipes with thermal insulation made of rigid PU foam are used for underground channel-free and over-ground laying of district heating pipelines. They extend pipe lifetimes by a factor of two or three, cut heat loss fourfold and reduce maintenance/operating costs.
