Neoprene 2045 is a high density foam rubber with excellent insulation, shock absorption, and water resistant properties. Higher densities of neoprene are more durable and resilient than lower density alternatives.

Key Characteristics
  • Closed-Cell Structure: Like other closed-cell foams, neoprene foam possesses a closed-cell structure, wherein its individual cells are enclosed, preventing interconnection. This arrangement affords the foam resistance against water, moisture, and air infiltration.
  • Flexibility: Despite its high density, Neoprene 2045 remains flexible, allowing it to conform to irregular shapes and contours, ensuring a proper fit and effective sealing or cushioning.
  • Chemical Resistance: Neoprene foam rubber exhibits good resistance to oils, greases, fuels, solvents, and most chemicals, ensuring long-term performance in various industrial and automotive applications.
  • Thermal Insulation: Neoprene foam rubber offers thermal insulation properties, helping to prevent heat loss or gain and maintain temperature stability in HVAC systems, pipes, and equipment.
  • Weather Resistance: High-density neoprene foam rubber is resistant to weathering, UV exposure, and ozone degradation, ensuring durability and longevity in outdoor applications.
Common Applications
  • Gaskets and Seals: It can be employed as gaskets and seals in industrial machinery, concrete, and construction applications
  • Padding: Used in shock-absorbing pads, bumpers, and cushions in automotive and aerospace applications
  • Insulation: It can be used as thermal insulation for pipes, HVAC systems, and industrial equipment
  • Weatherproofing: The foam is used for waterproofing and weather stripping for doors, windows, and construction joints
  • Reducing Vibrations: It sees use in vibration isolation mounts for machinery and equipment
