Iranpolymer\/Baspar <\/strong><\/em>The\u00a0race to replace\u00a0per- and polyfluoroalkyl substances (PFAS) is on, driven by increasingly stringent regulations and standards regarding these \u2018forever chemicals\u2019, some of which have been shown to have harmful impacts on human health and the environment.<\/p>\n

PFAS, however, have a plethora of diverse, useful, applications, and are therefore not easy to replace, particularly in high-end applications. There is\u00a0lack of viable alternatives to fluoroelastomers and fluoropolymers\u00a0in such applications, for example. Alternatives are starting to emerge, however, for example in\u00a0PTFE-free flame-retardant additives.<\/p>\n

Another example is Tosaf\u2019s new PFAS-free additives. The Israeli additive manufacturer has developed processing aids for the extrusion of polyolefins that do not contain fluoroelastomers.<\/p>\n

The first grade, AP9709PE EU, provides enhanced rheological properties which aid the flow of the extruded polymer. The second grade, AP9711PE EU, enhances optical properties including clarity and haze.<\/p>\n

The fluoroelastomers-free additives can be used \u2018without restriction\u2019 in place of standard products containing PFAS, according to Tosaf. They are suitable for a wide range of film applications and meet the requirements of the US Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) for use in contact with food.<\/p>\n

Tosaf performed laboratory tests to back its replaceability claims. It compared the processing properties of a\u00a0metallocene LLDPE with those of two of its compounds: one containing Tosaf’s standard fluoroelastomer-based processing aid (AP5645PE EU), and another with alternative PFAS-free additives. Results for flow behaviour \u2018were largely consistent\u2019, according to Tosaf, and the optical properties of the PFAS-free compound \u2018even showed slight advantages\u2019. The coefficient of friction of the PFAS- free film showed a \u2018negligibly lower\u2019 value.<\/span><\/p>\n

The new additives are already being used in some of Tosaf\u2019s customer applications, for example a 5-layer coex-line using 1\u00a0% of the<\/span>\u00a0AP9709PE EU additive in the outer layer.<\/p>\n

\u201cCompared to a standard PFAS-based processing aid, this enables a 5 C to 10 C lower melt temperature and shows a significant lower occurrence of melt fracture as well as improved optical properties such as haze,\u201d Tosaf said in a statement. It added that the films can be printed, sealed and laminated without any problems.<\/span><\/p>\n

\u201cTosaf has once again demonstrated that its expertise, combined with its state-of-the-art research, development and testing facilities, can deliver solutions that the market is looking for, but which were previously considered unthinkable,\u201d concluded Tosaf’s Chief Innovation Scientist Dr Evgeni Zelikman.<\/span><\/p>\n
