Kunststoffe international, From the Sea to Electronics
...ds For ocean-bound PET, experts from the Canadian company Lavergne were able to develop flame retarded formulations of their recycled polyester grades in close collaboration with Clariant’s specialists. Clariant’s Exolit OP halogen-free phosphinate flame retardants have a proven track record for a very good environmental and health profile, as documented by the GreenScreen Benchmark 3 assessment under the NGO Clean Production Action’s assessment tool, which identifies it as a good option to use ...

..., zinc sulphide (manufacturer: Sachtleben Chemie) can replace the antimony trioxide that is now being critically discussed. One flame retardant that is eminently suitable for polyamide is a product based on red phosphorous (grade: Exolit, manufacturer: Clariant), which guarantees outstanding flame protection with the addition of 50%. An innovative intumescing material (grade: Noflan CFB) has been provided by Russian space technology. With a filling level of between 14 and 30%, this forms a gas-t...

...romine flame retardant (PE68) and 25% antimony trioxide is supplied under the designation Fireblock 500 for polypropylene to simplify the processing operation. Clariant GmbH, Sulzbach/Germany, has developed a new organophosphinate, Exolit OP 1310, that attains a UL 94 V0 rating in a thickness of 1.6mm and a CTI index of 450 V in glass fibre reinforced polyamide 6. This flame retardant constitutes an attractive alternative to flame retardants containing bromine and to cycloaliphatic chlorine comp...

Transportation Flame-retardant Epoxy Resins Flame Retardants. While phosphorus-based flame retardants in epoxy resins often showed inadequate processing and material properties, recent work has succeeded in developing phosphorus-containing resins, curing agents and additives with significantly improved properties. Based on an organophosphorus compound, halogen-free, flame resistant epoxy resin systems can now be produced with good mechanical properties. There is no let up in the trend towards u...

...ant system by Clariant. This is based on a metal phosphinate, which is fundamentally suitable for halogen-free grades of engineering polymers in electrical/electronics applications and has met with a great deal of interest. The new Clariant grades Exolit OP 1311 and 1312 have been specially developed for glass-fibre reinforced polyamides. Both flame retardants are noted for their high CTI (Comparative Tracking Index) of 600 volts and their low compound density. Only small amounts need to be adde...

In a balancing act, Clariant flame retardants accomplish all these requirements. Exolit AP is based on an ammonium polyphosphate and thus is a non-halogenated flame retardant. In case of fire, ammonium polyphosphate decomposes into polyphosphoric acid and causes carbonisation. Carbon is bound to the component surface by the vitreous polyphosphat...
