FLAME RETARDANT POLYMER COMPOSITION

摘要

The present invention relates to flame retardant polymer compositions comprising a flammable polymer and an amount of between 1% to 40% by weight of tetrabromodipentaerythritol as flame retardant agent. Optionally, synergistic flame retardant additives such as antimony oxide are incorporated in the compositions. The flammable polymers are selected from polyolefins, polyamides and styrenic resins or mixtures thereof. The flame retardant agent according to the present invention imparts to the polymer compositions improved thermal aging behaviour, thermal stability and non blooming property, compared with known flame retardant agents.
