- Abstract
- When using materials with epoxy compounds as their basis under severe operating conditions (exposure to a spark, flame, or high temperatures), increased demands are placed on their fire resistance. The combustibility of normal epoxy polymers, evaluated by the oxygen index method (OI), equals 19,8-23.8%. One of the most efficient means of raising the fire resistance of epoxy polymers is introducing halogens, particularly tetrabromidphenylolpropane (TBD), into their structure. However, those polymers which possess a high fire resistance have at the same time low physical-mechanical indices, which limits their use.
