Sustainability / Natural Solutions
At Fakuma 2021 in Friedrichshafen, Tosaf/Afula, Israel, and its German subsidiary Tosaf Color Service, Karlstein, will highlight sustainability geared solutions in their wide range of functional, color and combi-masterbatches for extrusion and injection molding.
These will include color masterbatches for recyclates with a special focus on post-consumer plastics as well as biodegradable masterbatches. Another focus will be on e-mobility and electronics applications. Here, RAL 2003 Orange and a wide range of UL-listed colors make Tosaf one of the globally leading producers of masterbatches for the electronics and automotive industries.
A third key issue will be light diffuser solutions for polymethyl methacrylate (PMMA) and polycarbonate (PC), including colored grades. These fully harmonize the appearance of covers for light sources with the color of the surrounding frame or car body color, making them virtually invisible until illuminated.
Consistent Coloring of Recyclates
Due to source-related inconsistencies, recyclates from post-consumer scrap can show significant differences in their basic color. Tosaf has developed highly efficient masterbatches, specially tailored to cover such variations in a way that the final products meet the customers’ specifications within tight tolerances.
Supporting Biodegradability
Biodegradable polymers can provide sustainable alternatives to conventional grades, and this is particularly true for agricultural films. Typically, such films are manufactured with additives to provide specific functionalities ranging from UV stability to antifog and IR filtering effects. Tosaf has developed appropriate additive masterbatches based on biodegradable carriers such as polylactic acid (PLA) and resin (rosin).
Colors for Electronics and E-mobility
Going beyond traditional E&E applications, e-mobility defines new and demanding requirements. One of these is the need for polymers that maintain their orange warning color virtually unchanged throughout the life of a vehicle. Tosaf has set a worldwide benchmark with such a color masterbatch according to RAL 2003 for polyamides (PA6 and PA66), polypropylene (PP) and polybutylene terephthalate (PBT). The PA masterbatches were successfully tested at 130° C for 1000 hours without darkening. All grades are available with or without a laser marking additive for identification purposes.
Diffusing Light Sources
Punctual LED light sources are widely used to illuminate large outdoor advertising boards, car parks and outdoor roads, as well as small control panels in car interiors. This creates a growing need for translucent decorative covers with light scattering properties for a uniformly backlit surface. Tosaf has developed special light-diffusing (LD) masterbatches, especially for polymethyl methacrylate (PMMA) and polycarbonate (PC). In addition to color-neutral grades, combinations with specific colorings and other functional properties such as
UV stabilizers are also available.
