Polyurethane (PU/PUR) – Material properties and qualities
Polyurethane is a versatile, high-performance material for technical applications – abrasion-resistant, elastic, and chemically resistant. It can be customized and is ideal for complex requirements.
Overview of the material
Polyurethane elastomers offer an ideal combination of resilience, chemical resistance, and elasticity for a wide range of applications.
High mechanical strength without plasticizers
Resistant to oils, greases, and many chemicals
Elastic behavior – better than thermoplastics
Alternative to natural and synthetic rubber
Very good damping – reduced heating under dynamic loads
Outstanding properties
These specific characteristics make polyurethane the preferred choice for durable, heavy-duty solutions.
Very high strength and impact resistance
Extremely wear-resistant
Good damping values
Weather-resistant, even at temperatures between -50°C and 80°C (briefly up to 100°C)
Low compression set
Food-safe variants (EU/FDA-compliant)
