Tosaf to present latest masterbatch technology at Fakuma 2023

Tosaf has developed their masterbatches for applications on agricultural films, rigid and soft packaging, technical parts, as well as with sustainability requirements. The company will present their latest development in masterbatches at Fakuma 2023.

Laser additive for contour sharp markings

Tosaf’s new laser additive can be used for transparent applications without affecting the optical properties. It allows contour-sharp, high-contrast markings on thermoplastics, which originally show poor or even no color change laser marking, and on compounds with fillers such as calcium carbonate, talcum, titanium dioxide or carbon black.

Depending on the substrate, optional settings for marking colors ranging from white to grey to black are possible. As very low dosages are sufficient and the laser marking process can be fully automated, the new masterbatches reduce production costs compared to conventional processes such as labelling or embossing. Their use is also non-critical and more sustainable by eliminating the need for chemicals, varnishes or stickers.

The new masterbatches can apply to pipes, fittings, profiles, irrigation systems, as well as caps and closures for food and beverages packaging with their suitability for food contact. Customized combi-masterbatches are also possible.

Masterbatch carrier system for food contact

A new masterbatch carrier system from Tosaf Color Service meets all common food contact requirements, including those in Germany, the US and China. Therefore, this can be applied to translucent and opaque materials for rigid and flexible packaging, toys and household items, and even components for food processing machinery and equipment.

Masterbatches for light diffusing

Light diffusing (LD) masterbatches, which contain microfillers, can achieve uniform light distribution even with point-shaped LED light sources.

Tosaf’s light-diffusing masterbatches ensure uniform illumination even with LED spotlights.

Even with very small amounts of LD masterbatches, in a range of 1-2%, can result in highly efficient scattering of light in originally transparent material, mainly polymethyl methacrylate (PMMA) and polycarbonate (PC). The light transmission and mechanical properties of the base material are almost completely retained.

Even small amounts of masterbatch cause efficient light scattering in originally transparent polycarbonate.

Both color-neutral grades and combinations with specific colors and functional additives such as UV stabilizers are available.

Masterbatches for sustainability

With growing sustainability requirements, Tosaf also developed color masterbatches specifically for recyclates, with a focus on post-consumer plastics, which compensate for the materials’ origin-related inconsistencies. A special additive masterbatch is based on biodegradable carriers, such as polylactic acid (PLA) and resin, and gives corresponding agricultural films properties, such as increased UV stability, anti-fogging and IR filtering.

Another new sustainable development is chemically active blowing agents in plastics processing for the material-saving foaming process. The portfolio includes endothermic and exothermic types for a wide range of thermoplastics.

Endothermic grades are considered safe to use for food contact and require relatively low temperatures for activation. Their applications range from thin-walled films, molded parts with high surface quality, PP tapes, XPS and XPE trays for food packaging, and large and thick-walled parts.

Exothermic grades combine a high foaming effect with good dispersibility. Both blowing agents combined in one concentrate are particularly suitable for PVC applications such as sheets, profiles and pipes.
