The production of black polyethylene has been launched in Russia

The largest petrochemical plant of the SIBUR group, ZapSibNeftekhim (Tobolsk, Russia) has mastered the production of a new grade of polyethylene – PE-100.

The new product is distinguished by increased resistance to the external environment and an unusual appearance of the granules - they are black. The product is mainly used for the production of large-diameter pipes, which are in high demand in the oil and gas industry, housing and communal services and other areas - as an alternative to steel pipes. In the housing and communal services sector, polymer pipes can save up to 50% of the cost of maintaining water pipes and sewerage.

The performance characteristics of pipelines made of PE-100 are higher due to the addition of technical carbon to the original polymer, which is better known in everyday life as soot.

It is noted that the quality control of products at ZapSibNeftekhim is carried out constantly. As for the PE-100, the main parameters of the analysis are the type and class of distribution of carbon black in polyethylene. To determine how the carbon black is distributed in PE-100, the granules are frozen, cut into slices of a certain thickness, which are examined with a microscope and compared with samples approved by the licensor - the British petrochemical company INEOS.

The research makes it possible to control and, if necessary, adjust the dosage of carbon black, preventing poor-quality homogenization, which can lead to defects and deformation of pipes during its use. To check the quality of the produced granules, samples of pipes are also made in the laboratory of ZapSibNeftekhim, which are subjected to hydraulic strength tests.
