Protects and improves surfaces

Lining is finishing of working surfaces of equipment and parts with materials with special protective characteristics against mechanical, physical, thermal and chemical effects.

Lining prevents sticking, freezing or sintering of goods and wear of working surfaces of bunkers, wagons, conveyors during bulk, delivery and storage of bulk materials and cargo. The use of lining can increase the loading capacity of the equipment, and reduce additional operating, repair and service costs. As a material for the lining are proved polymers of company Plastmass Group: PLASTMASS™ UHMWPE/HMWPE and PLASTMASS™ PU.


The lining prevents sticking, freezing or sintering and wear of the working surfaces, bins, railcars, conveyors for the handling, transportation and storage of bulk materials and cargo. The use of linings allows to increase the throughput of the equipment, and to reduce additional operating costs for maintenance and repair of equipment. Polymers of the company Plastmass Group: high molecular and ultra high molecular weight polyethylene PLASTMASS™ UHMWPE/HMWPE and polyurethane elastomer PLASTMASS™ PU are proven remarkably effective.

At first is selected the optimal material for lining under the requirements of the Customer and according to preliminary calculations. Then are made the optimal maps of material’s cutting. The materials are available as plates of standard sizes and as well as plates in significant size, that reduces unnecessary loss of materials. Cutting is made on the exact machines; the cutting line is perfectly smooth, without burrs or rough edges. The choice of lining fasteners depends on the purpose of the equipment and the chosen material. The most appropriate and at the same time technologically effective method of the lining is fixing with bolts and studs. Plates made of materials are fastened to the bottom of the body by threaded studs, fixed on the surface by spot welding; the places of their installation are closed by plugs or welded. The joints of the plates are boiled with the hand extruder using welding rod. In order to prevent the getting of material under the lining surface, the upper edge of the lining sheets is closed with a steel plate.




Discover the lining process of surfaces.


Lining using high molecular and ultra high molecular weight polyethylene PLASTMASS™ UHMWPE/HMWPE has a wide range of technical characteristics:

  • Resistant to aggressive chemical environment, except the effects of nitric acid;

  • High wear resistance;

  • Excellent deformation characteristics, stable to size and shape changing;

  • No water absorbation, so no size changing in the aquatic environment;

  • UV and microorganisms’s destruction resistance;

  • No taste and smell;

  • The sliding surface prevents the sticking of wet products;

  • Mechanically strong and tough;

  • Low weight;

  • No extremely high costs by processing;

  • Good dielectric properties;

  • Radiation resistance.


Usinng polyurethane elastomer as lining (Shore hardness 70-90, Skala A) has following advantages:

  • Increased elasticity;

  • High wear resistance;

  • Resistant to numerous deformation;

  • Chemical resistance;

  • Dielectric properties;

  • Vibration resistance;

  • High pressure resistance without losing its operating characteristics;

  • No properties losing by temperature drops.
