Fire resistance and mechanical properties of a huntite/hydromagnesite/antimony trioxide/decabromodiphenyl oxide filled PP-PE copolymer
A natural mineral filler containing mainly huntite and hydromagnesite together with a blend of antimony trioxide (Sb 2O 3) and decabromodiphenyl oxide (DBDPO) was used to reduce the flammability of an ethylene-propylene copolymer. At the same time it was desirable to improve the stiffness of the cop...

Summary: | A natural mineral filler containing mainly huntite and hydromagnesite together with a blend of antimony trioxide (Sb
2O
3) and decabromodiphenyl oxide (DBDPO) was used to reduce the flammability of an ethylene-propylene copolymer. At the same time it was desirable to improve the stiffness of the copolymer without damaging its impact resistance even at high filler content. All the components and the resulting composites were studied by differential thermal (DTA) and thermogravimetric analysis (TGA). Specific flammability tests and mechanical tests were also carried out on the composites. The influence of the mineral filler and/or the Sb
2O
3/DBDPO blend on copolymer properties was investigated. The best results were obtained by combining both of the main components to give 25% mineral filler and 20% Sb
2O
3/DBDPO blend. |
