| Product Data: | Luwax EVA 3 is very versatile. It can be considered as being essentially a polyethylene wax with a molar mass typical for this group of substances, but because it contains vinyl acetate, it is more polar, more elastic and more finely crystalline than ethylene homopolymers. Luwax EVA 3 cannot be considered as being a true EVA polymer, as these are resins rather than waxes: they have a much higher molar mass and a higher vinyl acetate content. By using the relatively polar Luwax EVA 3 instead of the non-polar homo- polymer PE waxes, it is possible to produce masterbatches with very polar pigments like carbon black. The good wetting and excellent dispersing effect of Luwax EVA 3, which has a relatively low melt viscosity, leads to homogenous dispersion of the pigments with high colour strength. Luwax EVA 3 is especially effective in dispersing carbon black. It has a very high affinity for this type of pigment and its high wetting power enables very highly concentrated dispersions to be produced. Master- batches for PE, PP, PVC, polystyrene, nylon, polycarbonate, polyurethane and many other plastics can be prepared. The following example is a formulation of a pigment masterbatch for polyethylene and polypropylene: 15 % Luwax EVA 3 30 % Carbon black (e. g. Degussa Printex 60) 30 % LDPE moulding compound in powder form (e. g. Lupolen® 1800 SP 15) 25 % LDPE moulding compound in granular form (e. g. Lupolen 1800) The first step is to mix the carbon black and powder-grade LDPE, and then to add the granular components. The masterbatch is then extruded as usual. Other highly polar pigments are easy to disperse with Luwax EVA 3. Luwax EVA 3 is compatible with most thermoplastics. Universal master- batches consisting of pigments and waxes can be used to colour different plastics. |
