GLOXIL SF 91 A

Composites have long become standard in industry. In the fillers sector, too, they are already present in some cases, but often only as custom products. HOFFMANN MINERALl is now launching its first hybrid filler with Gloxil  SF 91 A.

Applications for the mixture of fiber and Neuburg siliceous earth with amino functionality lie in the field of thermoplastics. It excels in particular in applications where the mixture is required to achieve rigidity, toughness, scratch resistance and good processing of the compound.

FIELDS OF APPLICATION

Applications

  • visible parts and covers with good surface finish and very high scratch resistance
  • 3D printing
  • wood plastic composites (WPC)
  • films as functional fillers and matting agents

Polymers

  • Polyamides (PA)
  • Aliphatic polyketones (PK)
  • ABS
  • PP
  • TPU, PE/EVA

BENEFITS

Compared with unfilled polymer:

  • reduced warpage
  • increased hardness
  • increased scratch resistance
  • increased rigidity
  • increased tensile strength
  • increased flexural strength
  • increased heat resistance
  • increased thermal conductivity
  • better dimensional stability with fluctuating humidity (PA)

Compared with other mineral fillers:

  • good wetting and dispersion behavior
  • high melt flowability
  • no cross-linking in polyketone
  • relatively low warpage
  • high surface finish quality
  • very high scratch resistance
  • no graying with black pigmented compounds
  • increased rigidity
  • relatively high elongation at break
  • relatively high impact resistance, even at low temperatures
  • increased heat resistance
  • matting (in films)

Gloxil SF 91 A was tested in a PP copolymer compound by comparison with an ultra-fine premium talcum.
