| Product description: TEGOMER® P 121 is a dispersing additive based on amphiphilic copolymers especially designed for the preparation of color concentrates and technical compounds delivered in powder form. Application: TEGOMER® P 121 can be applied for single pigment dispersion and tailor made color concentrates for demanding dispersing processes. TEGOMER® P 121 is used for the dispersion of expensive additives, too, for so-called additive or combinational masterbatches. TEGOMER® P 121 can be used for masterbatches based on: - polyolefins (especially polypropylene)
- technical polymers (due to its high temperature resistance)
- but in filled compounds as well
TEGOMER® M-Si 2650 improves rheological properties during processing and surface characteristics in final parts. TEGOMER® M-Si 2650 is supplied as a low viscosity fluid which is introduced in pre-blending or direct feeding via liquid dosage. Benefits: The following advantages can be expected when TEGOMER® P 121 is used: - increase of color strength
- higher productivity and lower costs for coloration by reducing the amount of pigment
- higher filling grades of pigments
- less fiber fractures
- less agglomerates and aggregates
- excellent dilution behavior
- suppression of re-agglomeration in down-stream processes
- easy handling
- positive influence on masterbatch rheology
- excellent thermal and color stability
