Saytex Decabromodiphenyl oxide

A polyethylene flexible closed cell polymeric foam containing 22wt% of EG as fire retardant is capable of pass the test of FAR 25 Appendix F of U.S. Federal Aviation Authority similar results were obtained using 18wt% of EG and 5 wt% of Saytex 102E (Albemarle, decabromodiphenyl oxide) and 3 wt% of antimony oxide.95...

The flame-retarding of HDPE and PP is not so complex. 4.25 phr. of Saytex BN 451 and 2 phr. of antimony trioxide yield the rating V-2 for polypropylene. 6 per cent of octabromodiphenyl oxide and 3.5 per cent of antimony trioxide in 90.5 per cent of HDPE is rated B2 according to DIN 4102 (cf. Section 3.2.1) while the flammability of a compound with 9 per cent of decabromodiphenyl oxide and 4 per cent of antimony trioxide to 87 per cent of HDPE is rated B1. For reaching the classification V-0, a rather high portion of flame-retardants should be admixed, for example 30 phr of decabromodiphenyl oxide and/or BT 93 is recommended with 10 phr. of antimony trioxide to polypropylene. Masterbatches with these flame-retardants facilitate processing (cf. Table 5.15). The same systems are also used for polyolefin elastomers (such as EPDM) . 

Of the halogenated organics, brominated aromatic compounds are the most extensively used. Decabromodiphenyl oxide or Saytex BT-93 is approved, but poly-(dibromophenylene oxide) is specifically recommended for polyamides. Brominated epoxy resins are also suitable flame-retardants for polyamides. The synergetic partner additive is antimony trioxide in most cases.

Decabromodiphenyl Etherf 1163-19-5]. This is the second largest bromi-nated flame retardant, and is used in HIPS, textile backcoating, and in polyoleflns, generally together with antimony oxide. It is made, as are the other members of this series, by bromination of diphenyl ether and is commercially available by Albemarle as SAYTEX 102, Great Lakes Chemical as DE-83, and Dead Sea Bromine (DSBG) as FR-1210. In view of the large volume and multiple producers, it is priced favorably. The structure is as follows ...
