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)
UL 94 Regulations
- Rifra is affiliated with Underwriter Laboratories 94, the international body that originates this classification and that, after an approval process, releases the “yellow card” for certain products
- The UL 94 regulation provides three classifications ranging from V0 (the most severe) to V2 (the mildest)
- Our UL 94 certified products can be found on the website of the certifying body
