Product Description
Radiation Resistance GR Coupling / PU Coupling with Excellent Low Temperature Performance
Polyurethane Coupling (PU Coupling), GR Coupling, GS Coupling
Polyurethane elastomer is a synthetic polymer material that combines the high strength of plastic with the elasticity of rubber. This advanced material offers superior performance characteristics for industrial coupling applications.
Key Features
  • Wide hardness range (Shore A10-D80) with excellent elasticity even at high hardness
  • Exceptional tensile strength and load capacity exceeding standard rubber materials
  • Outstanding wear resistance (3-5 times better than conventional rubber)
  • Excellent resistance to oils, fuels, and mechanical lubricants
  • Superior resistance to oxygen and ozone degradation
  • Excellent vibration absorption and damping properties
  • Maintains performance in low temperature environments
  • High radiation resistance (performs well at 10-10 deg radiation dose)
  • Good machining properties for precise manufacturing
