Sealing materials in
Automotive Industry
Heavy Equipment & Rail Transport

Extreme Loads. Elevated Standards

The automotive, rail, and heavy-duty equipment sectors operate in some of the harshest mechanical environments. Components must perform reliably under constant vibration, exposure to oils and fuels, temperature fluctuations, and high dynamic loads. Every seal, bushing, guide ring, or sliding element must resist deformation and wear, even in long-term, heavy-duty conditions.

This industry includes:

  • Passenger and commercial vehicle manufacturing
  • Construction, agricultural, and municipal machinery
  • Rail transport — from locomotives to rolling stock systems
  • Power units, hydraulic systems, and large mechanical assemblies
  • Components That Matter

    In transportation technology, polymer-based components play a critical role in maintaining performance and safety:
  • Seals in hydraulic and braking systems
  • Shaft seals, O-rings, wipers, and guide rings
  • Bushings and support sleeves in suspensions and axles
  • Heat- and chemical-resistant gaskets in engines and gearboxes
  • Protective and sealing elements for cable passages and housings
  • These components must function under:

  • Constant mechanical stress and vibration
  • Temperatures up to +200 °C
  • Contact with oils, fuels, coolants, moisture, and dust
  • Seasonal freezing/thawing cycles
  • Sudden changes in pressure and load
