Sillikolloid P 87 offers best extrusion quality/edge smoothness and collapse resistance of complex profiles even at high extrusion speed, slightly higher tensile strength and tear resistance.
- low to very low moisture content
- enables high loading of filler and plasticizer
- excellent extrusion properties
- high surface quality
- high tensile modulus
- low compression set
