What is Polyurethane PU?

Polyurethane PU is a highly elastic structural material that belongs to the family of thermoplastic elastomers. Known for its superior anti-friction characteristics, Polyurethane PU is available in various colors and trade names, such as Vulkollan and Fibroflex. Its chemical composition provides exceptional resistance to friction, abrasion, and tears, making it a preferred choice in multiple industrial applications.

Key Features of Polyurethane PU

• Friction and Abrasion Resistance: Polyurethane PU exhibits outstanding resistance to friction and abrasion, ensuring longevity and durability.
• Shape Memory: Maintains its original shape even after prolonged deformation, making it ideal for applications requiring resilience.
• Vibration and Impact Reduction: Excellent at dampening vibrations and absorbing impacts, contributing to smoother operations and reduced wear.
• Chemical Resistance: Resists fats and most petroleum products, making it suitable for harsh industrial environments.

Applications

Polyurethane PU is utilized across numerous industries due to its versatile properties:

• Motor Vehicle Industry: Ideal for engine cushions and chassis sleeves (silentblocks), providing a longer service life than original parts.
• Industrial Purposes: Used in drive shaft couplings, high-diameter sprockets for bottle transportation, conveyor belt grab blades, various wheels and rollers, and shaft coatings. It is also used for lining bunkers exposed to abrasive materials like coal, gravel, and metal shavings.
• Construction and Road Machinery: Essential for base plates in vibrating plate compactors, blades in high-capacity concrete stirrers, grab blades for road roller rollers, and blades for snow removal machines.

Characteristics and Benefits

Polyurethane PU stands out due to its:

• High Elasticity: Provides excellent flexibility and resilience.
• Durability: Resistant to wear and tear, ensuring a long operational life.
• Versatility: Suitable for a wide range of applications, from automotive to industrial machinery.
• Chemical Resistance: Capable of withstanding exposure to various chemicals, including fats and petroleum products.
• Temperature Resilience: Maintains performance in extreme temperatures, making it reliable in diverse environments.
• Rigidity Options: Available in various hardness levels, such as 75 Shore A (light yellow) and 90 Shore A (light blue).
• Temperature Range: Operates efficiently within a temperature range of -30 ºC to +80 ºC.
• Density: 1.15 g/cm³, offering a balanced combination of strength and flexibility.
