SIBUR scientists have developed a specialized adhesive compound, LD17230 EC, for three-layer anti-corrosion polyethylene insulation of steel main pipes. The new material ensures reliable adhesion between the epoxy primer and the outer polyethylene coating and is intended for use in pipeline transport systems.
The development of the new grade is crucial for improving the reliability of main pipeline infrastructure, which plays a key role in the implementation of major infrastructure projects and ensuring the stability of raw materials and energy supplies. The quality of corrosion protection directly impacts the durability of pipes, operational safety, and the stability of pipeline systems throughout their lifecycle.
During industrial testing at steel pipe manufacturers, adhesion measurements using the LD17230 EC grade exceeded 270 N/cm. This confirms its high adhesion to steel and compliance with not only GOST R 51164-98, GOST 9.602-2016, and GOST 31445, but also the material's suitability for applying three-layer polyethylene insulation in accordance with the internal standards and regulations of major pipeline consumers.
The introduction of LD17230 EC to the market expands the availability of domestic materials for the construction, modernization, and repair of main pipelines. For the industry, this means reduced dependence on imported solutions for critical products, increased supply stability, and additional support for long-term infrastructure programs.
Vasily Mashukov, PhD in Chemistry, Director of Applied Research at the SIBUR PolyLab Research Center:
SIBUR's polymer solutions for the pipe industry include materials for the production of pipes and protective coatings aimed at increasing the reliability, durability, and efficiency of pipeline infrastructure.
The new solution is used in three-layer insulation as an adhesive layer between the epoxy primer and the polyethylene coating. The material is based on ethylene copolymers grafted with maleic anhydride functional groups, which ensures the required level of adhesion and stable performance properties.
Ruslan Khairullin, Director of the Engineering and Road Infrastructure Division at SIBUR:
"Trunk pipelines remain a fundamental element of large infrastructure systems, and the reliability of the solutions used directly impacts operational sustainability, the pace of modernization, and the implementation of new projects. Expanding the range of Russian materials in this segment helps reduce dependence on external supplies, improve the predictability of production chains, and create a more sustainable foundation for infrastructure development."
