Definitions
- the present invention relates to a flame retardant foamed styrene resin composition having good thermal stability and a foamed product thereof.
- styrene resin foam Since styrene resin foam is lightweight, it is used in various fields such as heat insulation applications such as home appliances and building materials and civil engineering applications such as embankment methods.
- Styrene resin is made of only carbon and hydrogen, and once ignited, it emits black smoke and burns violently. Therefore, depending on the application, it is necessary to add a flame retardant to make it flame retardant.
- a flame retardant bromine-containing compounds are widely used, and in order to impart high flame retardancy with a small addition amount, all bromine atoms such as hexabromocyclododecane (HBCD) are aliphatic carbon.
