TEGOPREN® 6879 is an organo-modified siloxane to be used for surface treatment of fillers, pigments and flame retardants making them easier dispersible in thermoplastics formulations. TEGOPREN® 6879 is also used in-situ during compounding.
Typical Applications
TEGOPREN® 6879 improves the dispersion of
Furthermore, TEGOPREN® 6879 is used as a liquid dispersing additive in the manufacture of masterbatches.
- Flame retardants, e.g. MDH or ATH
- Inorganic fillers e.g. titanium dioxide, talc
- Organic pigments, e.g. phthalo blues or DPPs
- Inorganic pigments e.g. ultramarine blue, iron oxides in polyolefines and engineering resins
Furthermore, TEGOPREN® 6879 is used as a liquid dispersing additive in the manufacture of masterbatches.
Benefits at a glance
By hydrophobizing the pigment / filler / flame retardant surface TEGOPREN® 6879 offers several advantages
- Up to 50% less water uptake, e.g. for flame retardents such as MDH
- Higher CTI values in E&E applications are achieved what is especially relevant for flame retardant compounds, e.g. MDH or MC for PA
- Applicable for organic flame retardents like MP, APP and MC resulting in no whitening in the water pelletizing bath used for polyolefine, PA or PBT
- Especially for TiO2 applications with high durability and long term resistance such as in PVC window profiles higher colour strength for pigments
- Higher filling grades for fillers and pigmentsexcellent rheological properties result in better redilution of masterbatches
- Improved mechanical properties
- Better dispersibility of pigments or fillers resulting in less speck formation and / or a higher degree of filling
