V.A. Belyi Metal Polymer Research Institute offers consumers High-impact polyamide materials for processing by extrusion and extrusion blow molding "Etamid EA-EU" under a manufacturing agreement and is looking for partners to conclude a distribution services agreement.

"Etamid EA-EU" is a highly impact-resistant polyamide composite material developed at the V.A. Belyi Metal Polymer Research Institute of the National Academy of Sciences of Belarus for extrusion processing, including blow molding.

Purpose/
The material is intended for the production of flexible tubes for the pneumatic brake systems of Belarus tractors (EA-EU (T) variant) and gasoline vapor separators for VAZ vehicles (EA-EU (V)). It completely replaces imported polyamide-11 analogs (Rilsan from Arkema, France), providing savings of over $10,000 per ton of product. [in fetch]

Characteristics/
Operates in a temperature range from -60°C to +100°C at pressures up to 8–10 MPa (with an operating pressure of 1 MPa in tractor pneumatic systems). [in fetch] It has high impact resistance and is suitable for continuous screw extrusion; its yield strength is approximately 39 MPa (composition data). It is produced using polyamide-6 with modifiers for increased strength and flexibility.

The main analogue is polyamide-11 (Rilsan by Arkema), which is replaced by "Etamid" in automotive and tractor equipment. [in fetch] Other ultra-strong polyamides for extrusion: PA6/66, PA6/12, FR-1000, PA-FR-1200, but they do not exactly match in impact resistance and application. Domestic extruded polyamides based on PA-6 with elastomers (Grodno Khimvolokno).

Main advantages. High impact resistance and low brittleness: Charpy impact strength of 15 kJ/m² at +23°C and 8 kJ/m² at -60°C, ensuring reliability under dynamic loads.

Wide temperature range: from -60°C to +100°C with retention of properties, suitable for extreme operating conditions.

High operating pressure: up to 7-10 MPa, outperforms similar materials in pneumatic systems.

Import substitution: replaces expensive materials such as Rilsan (Arkema, France), saving over $10,000 per ton of product.

Good processability: suitable for continuous screw extrusion and blow molding, lower cost compared to imported analogs with superior performance.

Applications in Processing
Extrusion enables the production of flexible polymer tubes of various sizes (from 4×0.75 to 16×2.5 mm) and colors for Belarus tractor brake systems and gasoline vapor separators.

Blown extrusion ensures resistance to petroleum products, including gasoline, for blown parts.

The material has been implemented at MTZ, Gomselmash and other enterprises in Belarus and the Russian Federation.

Currently, the V.A. Belyi Metal Polymer Research Institute is an academic scientific and technical complex focused on fundamental and applied research in two main areas:

1) Physicochemical foundations for the development of composite materials based on organic and inorganic polymers;
2) Surface physics, chemistry, and mechanics, analysis of contact interactions, friction, wear, and lubrication in technical and biological systems.

Within these areas, the Institute is a leading research and production complex in the following areas:

- Interfacial phenomena in polymer-polymer and metal-polymer systems;
- Weather resistance and durability prediction of polymer composites;
- Adaptive materials and structures;
- Physics and chemistry of lubrication;
- Sealing and filtration methods;
- Composite product design methods;
- Recycling of multicomponent polymer systems;
- Physics and technology of thin films;
- methods of surface analysis, description and classification of surface topography at the micro- and nanoscale, and solutions to contact and thermal problems in tribology;
- space tribology;
- friction and lubrication of natural and artificial joints;
- diagnostics and monitoring of machine friction units.

The most significant practical results have been achieved in the field of polymer materials science. Research by the Institute's scientists has significantly expanded the range of domestic polymer composites and products. Several dozen import-substituting and export-oriented polymer composite materials have been developed for mechanical engineering, electrical engineering, and agriculture.

In recent years, more than 40 brands of import-substituting and export-oriented polymer composite materials have been developed in the field of polymer materials science for mechanical engineering, electrical engineering, construction, and agriculture. Serial production of a number of materials has been launched at the Belneftekhim concern. The Institute exports many of its developments, primarily to Russia.

In the field of tribology, concepts of rough layer structure, friction surface morphology, and wear particle morphology have been developed. A number of computational methods and models for discrete frictional contact, friction thermal dynamics, and computer modeling of solid-state contact interactions have been developed. Based on fundamental research in this field, a number of new methods for analyzing material surface layers, including at the micro- and nanoscale, have been developed.

Every year, work is carried out under contracts with CIS and non-CIS countries (Russia, Ukraine, USA, France, the Republic of Korea, Switzerland, Poland, and others) for the development and supply of scientific equipment, new materials, and technologies.
