Polyurethane Seals

Practically all construction, mining and agricultural companies, as well as businesses involved in construction work, use hydraulic machinery. Its design includes various components such as hydraulic motors, pumps, accumulators, hydraulic cylinders, etc. However, this equipment can barely operate without special seals or gaskets.

Polyurethane seals are gaskets for various types of joints. They come in moving, static, contact and clearance types. They allow devices to rotate and let parts move relative to one another. In addition to seals, damper rings and gaskets also serve as sealing elements.

They too are made of polyurethane and come in various cross-sections. Polyurethane hydraulic seals are most often used on piston hydraulic pumps, presses, hydraulic shafts, rods, etc. They provide additional sealing and tightly close off gaps.

Seals made of polyurethane have a high level of elasticity, ensuring maximum tightness. Thanks to this, along with the material's unique structure, these parts protect against moisture, dust, dirt, fluid leakage, etc. Polyurethane is the most durable and reliable material for manufacturing seals.

Our company manufactures polyurethane gaskets and seals to sketches supplied by customers. For more detailed advice, you can contact our managers. All contact information is available in the corresponding section of the catalog.

Polyurethane gaskets are elastic, durable products used to create an intermediate layer between parts. They seal joints and cushion the operation of mechanisms and assemblies. These products resist deformation, aggressive environments, heavy loads and temperature fluctuations.

Even under elevated pressure, they retain their structural integrity and never lose their original properties. In addition, polyurethane gaskets have high abrasion resistance. Thanks to their light weight and resistance to mechanical loads, their service life is dozens of times longer than that of rubber equivalents.

The scope of application for polyurethane gaskets is quite broad. It covers industries such as metallurgy, chemicals, paper, molding, and others. In terms of technical and performance parameters, these parts fully outperform rubber, natural rubber and plastic.

As already mentioned, polyurethane rings and gaskets also serve as sealing elements. A damper ring is a component designed to seal moving and static parts of pneumatic, fuel, lubrication and hydraulic equipment mechanisms. Thanks to the material's increased wear resistance, the rings do not break down even after prolonged friction against metal components.
