Crastin® HR5330HFS BK591 Features & Benefits

Industry Needs

DuPontTM Crastin® is a stiff, tough PBT thermoplastic with superior electrical insulating properties. Crastin® PBT is the resin of choice for cost-effective, high-performing automotive radar systems.

  • Low dielectric properties for radar transparency.
  • Material and design solutions for radar absorbency.
  • Excellent dimensional stability and low warpage.
  • Excellent balance of mechanical properties.
  • Resistance to exterior environments, including road salt, automotive fluids, thermal cycling, and hydrolysis resistance.
  • Improved laser-marking properties.

 

Back Housing and Connector

  • Higher thermal conductivity for heat dissipation
  • EMI shielding (depending on requirements)
  • Improved toughness
  • Superior hydrolysis resistance for hot and humid environments
  • Improved thermal-shock-cycling resistance
  • Available laser transparent and improved laser marking
  • Low warpage for higher dimensional control
  • Standard grade with good mechanical properties

 

Mounting Brackets Sensor Support

  • Excellent combination of toughness and stiffness.
  • Good chemical resistance.
  • Extensive material data available for anisotropic analysis.
  • Improved laser marking solutions available.

 

Radome

  • Improved radio transparency with low Dk and low Df
  • Excellent dimensional stability
  • Improved toughness
  • Superior hydrolysis resistance for hot and humid environments
  • Available laser transparent and with improved laser marking
  • Low warpage for higher dimensional control
  • Standard grade with good mechanical properties
Industry Needs

DuPontTM Crastin® PBT resins offer clear advantages for vehicle manufacturers. Our materials help high-resolution camera windshield brackets stand up to the harshest environments.

  • Excellent dimensional stability and low warpage
  • Outstanding adhesive compatibility to secure component on the windshield for the life of the vehicle
  • Superior flow for easy processing of design features, such as snap fits and over-molded inserts
  • Improved laser-marking properties
  • Resistance to hydrolysis and low fogging.
