Gloxil SF 91 A
Gloxil SF 91 A
Gloxil SF 91 A is a hybrid filler consisting of a mixture of fiber and Neuburg Siliceous Earth with amino functionality used in the production of thermoplastics. It excels in particular in applications where the mixture is required to achieve rigidity, good toughness, scratch resistance and good processing of the compound
Features & Benefits
Compared with unfilled polymer:
• Reduced warpage
• Better dimensional stability with
fluctuating humidity (PA)
• Increase of
• hardness

• thermal conductivity
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)
