# Advantages of Polyurethane Products: Wear Resistance, Temperature, Lifespan

When a component with rubber bushings or steel parts fails after just a few weeks of operation, production halts due to wear. Replacing standard elements with polyurethane ones can significantly extend the lifespan of the component and reduce downtime and repair costs. This article explores why TIMOL polyurethane products offer real advantages for industrial enterprises and which solutions should be implemented in high-wear components.

## Why Polyurethane Outperforms Rubber, Steel, and Traditional Plastics
TIMOL polyurethane exhibits wear resistance 10 times greater than rubber, a wide operating temperature range from -60 to +100 °C, and the ability to vary hardness from 50 Shore A to 70 Shore D. This allows it to cover most tasks where standard rubber, steel, or plastics cannot withstand abrasives, impacts, or temperature fluctuations.

Due to its unique structure, polyurethane does not age under the influence of oils, does not crack in the cold, and does not develop cracks from moisture or UV radiation. In real-world applications in mining, metallurgy, or pipe rolling lines, polyurethane bushings, bands, or linings operate where rubber or steel parts require replacement much more frequently. This is achieved through the free casting technology, which allows for the production of any complexity product according to drawings, with precise property selection for a specific component ([see catalog](/katalog)).

## Comparative Table of Properties: Polyurethane vs. Alternatives
The most convenient way to compare materials is by key characteristics. The table below provides numerical indicators for polyurethane and main alternatives based on reference data:

| Material | Abrasion (DIN 53516), mm³ | Working t, °C | Hardness (Shore) | Tensile Strength, MPa | Density, g/cm³ |
|---------------------------|---------------------------|----------------|-------------------|------------------------|----------------|
| Cast Polyurethane | 20-45 | -60...+100 | 50A - 70D | 25-60 | 1.05-1.25 |
| SBR Rubber | 100-200 | -40...80 | 40A - 80A | 8-20 | 0.94-1.1 |
| NBR Rubber | 80-150 | -30...100 | 40A - 90A | 10-25 | 1-1.3 |
| Caprolon (PA6/PA66) | 30-90 | -40...100 | 75D - 85D | 60-85 | 1.13-1.15 |
| Structural Steel |, | -40...500 | 120-250 HB | 370-700 | 7.7-7.9 |
| UHMW-PE | 15-30 | -200...80 | 60D - 70D | 17-45 | 0.93-0.95 |

These data confirm that polyurethane abrasion is 20-45 mm³ according to DIN 53516, while for SBR rubber, this figure is 5-10 times higher (100-200 mm³). Caprolon and UHMW-PE have similar or lower abrasion, but polyurethane excels in elasticity and impact damping. Steel has significantly higher strength but is 6-7 times heavier, does not dampen vibrations, and transmits impacts to the component, accelerating the wear of bearings and fasteners.

## Optimal Temperature Range and Stability in Any Conditions
TIMOL polyurethane is designed for stable operation from -60 to +100 °C, covering the needs of workshops with rapidly changing conditions, cold storage, open areas, as well as components near heating equipment. In these conditions, traditional rubber (SBR, NBR) either cracks in the cold or softens with rising temperatures. EPDM rubber can withstand temperatures up to 120 °C but is less resistant to oils and aggressive environments.

In mining and metallurgical components, polyurethane linings for gravity equipment, scrapers, seals, and screens demonstrate dimensional and elasticity stability even with frequent starts and stops of the production line. Unlike steel, which can corrode with condensation or acid contact, polyurethane does not require additional protection and retains its shape under sudden thermal shocks.

## Flexibility in Hardness: From Soft Seals to Hard Rollers and Linings
A key advantage of polyurethane is the ability to select hardness for the task: from 50 Shore A (soft dampers, seals, gaskets) to 70 Shore D (hard rollers, bands, bucket elevators). This allows for the production of a product with optimal elasticity, wear resistance, and shock absorption for each component. In comparison, most rubber materials have a limited working hardness range, while caprolon and UHMW-PE are rigid, hardly absorb shocks, and are prone to destruction under impact loads.

At the TIMOL plant, for example, scrapers for belt cleaning or chute linings operate under constant abrasion and vibration. They are selected with hardness at the upper range to ensure maximum service life. For seals and gaskets, elasticity and shape recovery after deformation are important, with optimal softness in the range of 50-60 Shore A.

> For components with strong abrasion or vibration, choose polyurethane hardness closer to 70 Shore D. For seals and dampers, up to 50 Shore A. The optimal option is selected individually based on the task and operating conditions.

## Manufacturing Polyurethane Products to Size and Drawing
TIMOL polyurethane products are manufactured using free casting technology, allowing for the creation of parts of virtually any shape, with complex geometry, holes, and fittings for shafts or flanges. The process begins with the preparation of a mold (metal or silicone), after which the raw material is poured into the mold, where it polymerizes under temperature control. This ensures minimal internal stress and precise dimensional conformity.

For mounting, standard seating places, keyways, flange holes, and threaded inserts are provided. For example, polyurethane rollers are mounted on axles through special bushings, while chute or hydrocyclone linings are attached with bolts or adhesive to metal housings. Drawing development or manufacturing by sample is possible for equipment that is no longer produced.

## Practical Advantages in Installation, Maintenance, and Repair of Components
The installation of polyurethane products is simplified due to precise manufacturing to fit the seating dimensions and lower weight compared to steel. When replacing rubber or steel elements (such as scrapers, bushings, sealing rings) with polyurethane, no modification of the component is needed, just adherence to the same seating and fastening parameters. Linings and seals are easily mounted and quickly removed for maintenance.

Maintenance is reduced to periodic inspection and cleaning from adhered abrasives or oils. Polyurethane does not require lubrication, is not subject to corrosion, and does not age even in contact with aggressive environments. In case of component failure, it is promptly manufactured according to the drawing or sample, which is especially valuable for equipment with no market analogs ([see reference information](/informatsiya)).

## Where Polyurethane is Economically Beneficial: Typical Components and Replacement Effect
Polyurethane provides the greatest economic return where rubber or steel parts wear out due to abrasives, oils, or repeated impacts. For example, in bucket elevators, rollers, hydrocyclones, concrete mixer scrapers, seals, and linings for gravity equipment. With wear resistance 10 times higher than rubber, replacement and downtime costs are significantly reduced.

In metallurgy and mining, polyurethane screens, shaker parts, bushings, and rings withstand loads that are critical for rubber or plastic within a month or two. In pipe rolling, railway transport, food, and pulp and paper industries, polyurethane solves sealing and damping issues in components where precise dimensional conformity and property stability under temperature and humidity are required.

## Polyurethane in 12 Industries: Versatility and Adaptability
TIMOL cast polyurethane products are used in 12 key industries: mining, metallurgy, mechanical and automotive engineering, oil and gas industry, railway transport, pipe rolling production, pulp and paper, printing, food, docks and ports, agriculture, and light industry. In each field, polyurethane parts (from rollers to linings) are selected based on the specific load and environmental conditions.

The customer receives not only a part but also full support, material selection, hardness, drawing development, and installation recommendations. Thanks to free casting technology and adaptable properties, polyurethane allows for the modernization of components in both old machines and new lines, increasing resource efficiency and reducing maintenance costs.
