Sillikolloid P 87 in car body seals

Sillikolloid P 87 offers best extrusion quality/edge smoothness and collapse resistance of complex profiles and stability as well as lesser matting effect, 
higher tensile strength, tear resistance and least wear.

 

  • good extrusion properties
  • high surface quality
  • low moisture content
  • high tensile modulus
  • low compression set
  • high electrical resistance (compared with carbon black)
