Klaus Rathberger, Georg H. Luh, Germany, outlined the benefits of his company’s expanded graphite as a PIN flame retardant system component. Applications include EPS, foams in transport applications (automotive, aircraft), compounding for thermoplastics, rubber,...
Sinikka Freidhof, Lubrizol, presented CPVC, in which the chlorine content of PVC is increased from around 55% to around 67% through a post chlorination process. The modified polymer offers improved rigidity and fire performance following the increase in chlorine...
Daniel De Schryver, Albemarle, presented new polymeric brominated flame retardants for thermoplastic resins (styrenic polymers ABS/HIPS). Advantages include thermal stability (compatible with injection molding), melt blending, aesthetic quality (gloss), colour...
Caroline Braibant, International Antimony Association (I2A) presented the “hazards” of antimony and stewardship measures engaged to enable safe use of antimony trioxide (ATO). The known hazards are lung toxicity, lung cancer, delayed ossification and maternal...
Karen Janssens, Campine, presented an assessment of antimony use as an FR synergist, using the ICL SAFR methodology (see pinfa Newsletter n°79), including testing blooming of antimony in plastics (migration to the surface). In most polymers tested blooming was not...
