    Tosaf to boost capacity, portfolio and service in polycarbonate additives

    Tosaf strengthens its commitment around additives for polycarbonate (PC), which are mainly used for the extrusion of transparent sheets, profiles and films.
    This includes the development of new, market-driven specialties as well as the development of new markets worldwide. A recently commissioned cutting-edge
    compounding line at the Alon-Tavor site in Israel increases the company’s flexibility in meeting customer requirements, while at the same time shortening delivery times and expanding options for producing sophisticated masterbatches.

    Additional functionalities

    Tosaf’s new developments include light diffuser masterbatches for PC and PMMA. Thanks to a high loading level, low dosing quantities are sufficient, enabling particularly economical solutions. On top of that, they offer a good compromise between high hiding power and high light transmission. Other innovations are heat blockers for the near IR range (NIR blockers)  and additives for creating matt surfaces with either a fine or rough structure. Both of the latter are intended to be applied to the surface of PC sheets by coextrusion, each in combination with a UV absorber. As a 50 µm to 100 µm thick toplayer, they work much more efficiently there than when added directly to the sheet bulk. Beyond, Tosaf also offers two types of anti-block that are tailored to prevent corrugated sheets from sticking together, again providing high efficiency even in small doses.

    In addition to the aforementioned products for UV stabilization as well as for achieving matt surfaces, near-IR blockers and anti-block additives, Tosaf’s portfolio of compounds and masterbatches for PC also includes flame retardants, glass fibres and a wide range of color masterbatches.

    Supply security worldwide

    To meet the strictest quality requirements, Tosaf produces its entire portfolio of polycarbonate compounds for global demand exclusively in its Alon-Tavor additives factory, which is state-of-the-art regarding the production and quality assurance of these sensitive products. All new and further developments are also carried out in Tosaf’s development centre at the same location, which makes the scale-up to production conditions much safer and easier. Only the production of color masterbatches for PC takes place in a dedicated color compounding site, which is also located in Israel. Local supply to PC sheet manufacturers is handled by sales offices in Europe, South America, North America, Turkey, Asia, China and India, the Persian Gulf and the Israeli market.

    Says Gabi Bar, polycarbonate product manager: “For some years now, we have been registering a steadily growing demand for our products on the part of PC processors. We see the reasons for this in our consistently high level of quality as well as in the continuous development of new, demand-oriented specialties that fill gaps. Added to this is our worldwide development of new markets, which we serve at the local level with efficient logistics. Our new facility in Alon-Tavor will increase our flexibility in supplying our broad portfolio of polycarbonate products and further reduce lead times.”

    For over three decades, Tosaf ( has been developing and manufacturing high-quality additives, compounds and color masterbatches for the plastics industry. With the aim of providing for its customers’ every need, it has continuously grown and developed its offering, production capacity, and global reach, becoming a truly close to the market, global organization.
