Better protection against decomposition and fire
Nanoparticles prove doubly effective
Invisible: Tiny nanoparticles will improve the properties of the plastic manufactured from these granules.
Nowadays all plastics should be routinely equipped with flame retardants. The first environmentally friendly flame retardants came onto the market in the late 1980s, replacing hazardous chemicals based on chlorine and bromide compounds with less harmful phosphates. But they had one disadvantage: plastics containing phosphate additives became brittle relatively quickly. Researchers at Bayer MaterialScience have now found a solution to this problem.
Customized plastics
In particular, phosphate-containing plastics rapidly developed cracks when they were exposed to high temperatures and high atmospheric humidity. Tests showed that, under these conditions, phosphates degrade to form phosphoric acids which in turn attack the plastic molecules. Read the following article to find out how researchers at Bayer succeeded in combining the right quantities of the right ingredients to produce a plastic with better flame retardant properties and better resistance to hydrolysis.
