Comparison of the relative cost effectiveness of brominated and chlorinated flame retardants in EPDM was written by Lesniewski, Joseph M.. And the article was included in Proceedings of International Wire and Cable Symposium in 1980.Category: indole-building-block This article mentions the following:
The relative effectiveness of cyclooctadiene-hexachlorocyclopentadiene Diels-Alder diadduct (I) [13560-89-9] and tetrabromophthalimide (II) [24407-32-7] as flame retardants was studied in calcined clay-filled 80:20 (weight) EPDM rubber-polyethylene [9002-88-4] standard formulations (revised NDX 5117) for wire and cable applications. The flame retardant component was removed from the standard formulation (containing 30 parts flame retardant) until 0, 10, 15, 20, or 30% removal of fire retardant was obtained. The 200% modulus was higher and % elongation was slightly lower for formulations containing II. Ratings from the O index test indicated a better response from II than from I in all formulations. The UL-94 flame test indicated that only the standard formula and the formula with 10% removal of II gave a 94-VO rating; the formula containing I burned under UL-94 testing. The VW-1 flame test indicated that the standard loading for I was at its optimum for the system and that further lowering resulted in failure; the amount of II was lowered by 闂?0% before failing the VW-1 test. In the experiment, the researchers used many compounds, for example, 4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7Category: indole-building-block).
4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7) belongs to indole derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. More than 200 indole derivatives have already been marketed as drugs or are under advanced stages of clinical trials.Category: indole-building-block
