When a process engineer searches for “liquid polyurethane to buy in Ukraine,” the real need behind the query is usually not raw material in drums — it is finished polyurethane parts: bushings, seals, rollers, scrapers, linings. Purchasing raw liquid components only makes sense when you have your own casting equipment with precise dosing, degassing, and temperature control. Without that setup, self-casting produces inconsistent hardness and internal voids. TIMOL factory offers the correct alternative: finished parts produced by the free-casting process with guaranteed properties at every unit. This article explains what free-cast polyurethane delivers in numbers, how it compares with rubber, capron, and steel, and how to order in Ukraine.
What Free-Cast Polyurethane Delivers
The free-casting process — pouring a two-component polyurethane mix into an open or closed mould without high pressure — gives the factory precise control over all part properties. Hardness is set from 50 Shore A to 70 Shore D by formulation before casting. Abrasion per DIN 53516: 38-39 mm³, approximately 2-5 times lower than standard SBR rubber. The part recovers its geometry after impact and compression thanks to rebound elasticity of 34-61 %.
The operating range of -60 to +100 °C means that the same part formulation works in frost and in a heated process unit without brittleness in cold or flow in heat. Tensile strength 39-87 MPa is several times higher than any rubber. The material does not corrode, does not absorb moisture, and is resistant to oils, petroleum products, dilute acids, and alkalis.
In practice, these properties mean a single polyurethane part can replace several materials in one node simultaneously. Where steel is needed for wear resistance but fails on corrosion, and rubber is suitable for elasticity but cannot tolerate oil, polyurethane is often the only material satisfying all conditions at once. Technical testing methodology is described in the reference information section.
Properties Comparison Table
| Material | Abrasion DIN 53516, mm³ | Operating t, °C | Density, g/cm³ | Tensile strength, MPa | Rebound elasticity, % |
|---|---|---|---|---|---|
| Polyurethane TIMOL | 38-39 | -60…+100 | 1.05-1.25 | 39-87 | 34-61 |
| SBR rubber | 100-200 | -40…+80 | 0.94-1.1 | 8-20 | 30-55 |
| NBR rubber | 80-150 | -30…+100 | 1.0-1.3 | 10-25 | 20-45 |
| Capron PA6/PA66 | 30-90 | -40…+100 | 1.13-1.15 | 60-85 | 5-15 |
| Structural steel | n/a | -40…+500 | 7.7-7.9 | 370-700 | n/a |
The table shows that polyurethane occupies a unique position: among elastomers it has the lowest abrasion while retaining resilience. Capron is close on abrasion but is nearly inelastic (5-15 % rebound) and absorbs moisture. Steel is strong but 6-7 times heavier and has no damping. NBR rubber is oil-resistant but wears 4-7 times faster. Polyurethane is the only material in the list that combines low abrasion, elasticity, oil resistance, and corrosion resistance in one part.
Engineer’s tip: when evaluating the economics of switching a node to polyurethane, calculate not the part price but the annual cost of the node: part cost multiplied by number of replacements per year, plus downtime cost per replacement. A polyurethane part with a 3-5 times longer service life delivers savings even at a higher part price, because the replacement labour and downtime cost dominates for frequently replaced components.
What Is Produced from Liquid Cast Polyurethane
The range of parts produced by the free-casting process at TIMOL covers 12 industrial sectors. In the automotive and transport sector: bushings, silent blocks, spacers, seals, cuffs, and suspension dampers. In mining and metallurgy: lining sheets for bunkers and chutes, conveyor scrapers, idler rollers, and wear-resistant guides. In mechanical engineering and manufacturing: wheels, rollers, press dampers, guide sleeves, and gaskets.
In the food industry: conveyor belts, scrapers and guides that do not leave marks on the product, formulations resistant to food acids and washing solutions. In the chemical and oil-and-gas sector: seals, linings, and gaskets resistant to petroleum products and chemicals. In agriculture: polyurethane parts for seeding, sorting, and harvesting equipment that work in abrasive grain and fertiliser environments.
The product range lists standard part configurations; custom orders to any drawing, sketch, or sample are the most frequent way of ordering: an engineer submits a worn part or a dimensional sketch, and the factory reproduces it in the required hardness and formulation.

How to Order Cast Polyurethane Parts in Ukraine
To place an order, supply a drawing, worn sample, or description of the part: dimensions, required hardness, and operating conditions (working medium, temperature, load character). The factory technologist will select the optimal formulation, calculate geometry with machining allowances if necessary, and arrange production.
TIMOL factory is in Dnipro and ships throughout Ukraine. Both single parts for a one-off repair and production batches for a fleet of equipment are produced. Lead time depends on part complexity and batch volume; standard configurations are produced in the shortest time from stock raw material. For consultation, hardness selection, and ordering, contact TIMOL factory. Engineers will recommend the optimal formulation and arrange production.
