Polyurethane (PU or PUR) Plastic Extrusions

Lakeland Plastics manufactures high-performance polyurethane (PU) extrusions designed to deliver exceptional flexibility, abrasion resistance, and long-term durability across demanding applications.

Material Name: Polyurethane (PU)

PU, or polyurethane, is a highly versatile thermoplastic known for its unique combination of elasticity, toughness, and resistance to wear. Widely used in plastic extrusion, PU bridges the gap between rigid plastics and flexible rubber materials, offering both structural integrity and flexibility in a single solution. Its ability to withstand abrasion, repeated impact, and harsh environments makes it an ideal choice for applications that require long-lasting performance under stress. Polyurethane can also be formulated in a range of hardness levels, allowing it to be tailored for both soft, flexible profiles and more rigid, load-bearing components.

Polyurethane: Definition

Polyurethane (PU) is a polymer formed through the reaction of polyols and isocyanates, resulting in a material that can be engineered with a wide range of mechanical properties. Depending on its formulation, PU can behave like a flexible elastomer or a rigid plastic, making it highly adaptable for extrusion manufacturing. It is classified as a thermoplastic elastomer when processed for extrusion, meaning it can be melted, shaped, and reprocessed while still maintaining rubber-like elasticity and resilience. This versatility allows polyurethane to deliver excellent performance across a broad spectrum of industrial and commercial applications.

Pros of Polyurethane

  • Excellent abrasion and wear resistance
  • High flexibility and elasticity
  • Strong impact resistance and ability to absorb and distribute loads
  • Resistant to oils, greases, and many solvents
  • Performs well in harsh and high-friction environments
  • Maintains durability under repeated stress
  • Good tear resistance compared to many flexible plastics
  • Can be formulated for both soft and rigid applications
  • Weather-resistant with proper additives
  • Long service life in demanding conditions

Cons of Polyurethane

  • Higher material cost compared to commodity plastics
  • Can be sensitive to prolonged UV exposure without stabilizers
  • Processing can be more complex than standard thermoplastics
  • Limited resistance to very high temperatures
  • May absorb moisture depending on formulation
  • Less rigid than structural plastic
