HFFR for safe fire protection with PP
FR8719PP is an innovative, halogen-free flame retardant (HFFR) from Tosaf for PP pipes or moulded parts that are used, for example, for laying and fixing cable conduits and for conducting liquid media. Even in low concentrations, it makes it easy to comply with strict fire protection criteria and thus enables a switch to a more sustainable solution without the products losing any of their flame retardancy and properties. Processing advantages are the good dispersing behaviour in the melt and the very low formation of dye build-up during extrusion. If halogen-free is not a priority, brominated flame retardants such as FR6413PE and chlorinated, low-cost grades such as FR0049PE from Tosaf offer high thermal stability and fire protection without compromising the product properties.
PFAS-free for improved processability
Tosaf's PFAS-free processing aids for the extrusion of polyolefins can be used without restriction instead of conventional formulations for film production. They meet the FDA and EFSA food contact requirements and, depending on the grade, are optimised in terms of either their rheological or their optical properties such as light transmission, haze and clarity. The unproblematic behaviour of PFAS-free monomaterial PE films in recycling is an advantage.
Coloured PPA without loss of properties
With PPAX, Tosaf Color Service has developed a new colour masterbatch carrier system that is based on the high-performance plastic PPA (polyphthalamide) and is combined with specially selected pigments that allow high processing temperatures. This makes it possible to produce products made with it in brilliant and varied colours without reducing the high heat resistance, very good strength, stiffness and toughness, low moisture absorption and high chemical resistance. It can also be used to laser mark coloured parts.
Documented sustainability
Tosaf is leading the way on the ‘green path’. It quantifies and reports on its carbon footprint down to product level, utilises solar energy and offers a portfolio of products based on renewable sources or recyclate. Thus, the company is already prepared for a further tightening of regulations. At the same time, Tosaf is fulfilling its customers' desire to maintain relationships with environmentally conscious partners. The company has already undergone global validation for the ISO 14064 standard for quantifying and reporting greenhouse gas emissions in 2021. This now covers the entire life cycle of a product and does not end at the factory gate. Tosaf calculates its carbon footprint for the production facilities as a whole as well as for the products themselves and makes the results available to customers on request to calculate their own sustainability figures.
Tosaf is also continuously expanding its portfolio of sustainable solutions. Options include bio-based concentrates that use coffee grounds and eggshells as fillers, polymers from renewable sources and recycled polymers. These are supported by a collaboration with recycling plants for various polyolefins and polystyrene.
