Made up of both filament and staple fibers, the polyester is produced by a raw fiber reforming method in which the flame retarder
is copolymerized at the raw fiber manufacturing process.
The base polymer polychloroprene itself contains about 38-40% chlorine which acts as a flame retarder. Although the LOI value acc.
This will be demonstrated with a typical formulation developed in our laboratory containing zinc borate, aluminum trihydrate, antimony oxide and chlorinated paraffin as additional flame retarder.
This may be due to the fact that each flame retarder works at a specific temperature, different from the combustion temperature of the other ingredients.
* this flame retardancy can be further improved by addition of flame retarders. Widely used are chlorinated paraffins, antimony oxide, boron-compounds such as zinc borate, aluminum trihydrate and phosphate plasticizers.
It also provides for a total ban on the use of F-gases for a series of equipment and products, including flame retarders
from 2016 onwards, and new equipment placed on the market, such as refrigerating and freezing equipment for commercial use by 2020 or 2022, according to their global warming potential (GWP).
The company's zinc borate is said to work in concert with virtually all other flame retarders
. The synergy with antimony oxide allows half as much antimony material to be used to obtain comparable results, according to the company.
can have toxic effects on health and the environment: some of them were completely banned two years ago, under the Directive on hazardous substances found in electrical and electronic equipment.
The Council has left the issue of electric light bulbs, welding equipment and flame retarders
hanging - this will be decided upon when the Directive is reviewed (it must be reviewed within five years of coming into application).Disappointment for manufacturers.In a press release, the European Association of Consumer Electronics Manufacturers (EACEM) expressed its disappointment at the Council's decision.
The German delegation told the Council about a recent mission also sent to the area.In reaction to Sweden's call for progress to be made on the question of bromated flame retarders
, the Commission announced that the United Kingdom, in charge of assessing risks in this area, said it will probably be handing in its findings sometime during the next few weeks.
