Flame retardants

Their purpose is to reduce plastic materials flammability by controlling the combustion process through different mechanisms such as:

    • Developing gas
    • Intumescence
    • Melting (absorbing flame generating heat)
    • Acting on the chemical reaction (slowing it down)

 

Possible problems and interactions on the item

Mechanical changes
– a reduction in breaking load: tensile strength
– impact resistance level – izod
Surface migration (blooming): surfacing of flame retardants which carries a sometimes sticky patina with an unpleasant aesthetic effect
Reduction in strength under sunlight (premature yellowing of the resin, UV deactivation)Rheological changes (MFI, processability conditions)
Requests/exemptions (halogens, bio-compatibility with antimony)
