Features Of 3M PUR 4003 Polyurethane Elastomer

  1. Excellent abrasion resistance for extended service life in high-wear environments.

  2. High tensile strength and elongation at break, enabling robust mechanical performance under dynamic loading.

  3. Good resistance to oils, greases, and many industrial solvents.

  4. Low-temperature flexibility down to –30 °C without significant loss of elasticity.

  5. Easy processing via casting, centrifugal casting, or injection molding with standard polyurethane equipment.

Typical Applications Of 3M PUR 4003 Polyurethane Elastomer

  1. Industrial rollers and idler wheels for material handling and conveyor systems.

  2. Mining and quarrying equipment components including screen panels and chute liners.

  3. Heavy-duty wheels and casters for automated guided vehicles (AGVs) and material transport carts.

  4. Seals, gaskets, and custom-molded parts requiring resilience and chemical durability.

  5. Wear pads and impact-absorbing bumpers in automotive and off-highway machinery.
