Polyurethane (PUR) is an engineering elastomer with outstanding abrasion resistance, excellent impact absorption and controlled flexibility. It is widely used for shock absorbers, wear liners, rollers, bushings, rings and industrial components. Due to its long service life and stable mechanical behavior, polyurethane is an ideal material for harsh and heavy-duty working environments.
What is Polyurethane (PUR)?
Polyurethane (PUR), also commonly referred to in industry as poly urethane,
is a high-performance engineering elastomer known for its unique combination of
exceptional abrasion resistance, excellent impact absorption, high toughness,
controlled elasticity and long service life.
These properties make polyurethane one of the most reliable materials for heavy-duty,
wear-resistant and shock-absorbing industrial applications.
Engineering Properties of Polyurethane (PUR)
- Outstanding abrasion resistance: Ideal for continuous wear and harsh operating conditions.
- Excellent impact absorption: Highly suitable for shock absorbers and vibration damping.
- Controlled flexibility: Allows deformation under load without permanent damage.
- High toughness: Good resistance to tearing, cracking and fatigue.
- Low surface adhesion: Suitable for liners and material-handling rollers.
- Good chemical resistance: Compatible with many oils and industrial fluids.
- Long service life: Stable performance under heavy load and severe wear.
Industrial Applications of Polyurethane (PUR)
- Industrial shock absorbers and vibration dampers
- Wear liners and abrasion-resistant plates
- Rollers and conveyor components
- Flexible bushings and rings
- Semi-flexible CNC-machined components
- Bulk material handling and loading equipment parts
- Mining, construction, packaging and heavy machinery industries
