HBCD – free flame retardant masterbatch for extruded polystyrene
Chemical name: 1,1-(Isopropylidene)bis[3,5-dibromo-4-(2,3-dibromo-2-methylpropoxy)benzene]
Product name: ADCHEM FRPS130 master batch
ADCHEM FRPS130 is HBCD- free, brominated flame retardant masterbatch for XPS. Meanwhile, the thermal stability additive is added in the masterbatch. It provides good flame resistance and allows high processing temperatures.
This FR masterbatch meets RoHS legislation. And doesn’t have SVHC materials.

Addition level
Typically dosage: 1.5% – 5% to reach DIN 4102 B1 standard for XPS. It also depend on the process condition and final application.
Processing
We suggest the process temperature below 230 °C. The extruder should be washed after finished the flame retardant grade XPS foam.
Many factors will bring the effects for the finished XPS. Such as the raw material of polystyrene, the thickness of the product, and the different processing equipments… The production needs right technical and knowledge.
Background
Hexabromocyclododecane (HBCD), an additive brominated flame retardant, is one of the persistent organic pollutants and is widely used in building insulation materials all over the world. HBCD will be banned or eliminated globally under the Stockholm Convention on Persistent Organic Pollutants. The reporter learned from the Provincial Department of Ecology and Environment on November 1, 2021 that 8 production enterprises across the country with a capacity of 28,000 tons of HBCD are all in our province. By the end of October, the HBCD production lines of the 8 production enterprises have been dismantled, and the HBCD inventory has been cleared. In the middle of 2022, our Shandong province will realize all raw materials, products and wastes containing HBCD to zero totally.
ADFR 130 is one of the substitute flame retardant to replace HBCD. The Cas number is 97416-84-7. EC/ List number is 306-832-7. It is mainly used for EPS and XPS. Besides the powder, we can supply the masterbatches of ADCHEM FRPS130. The manufacturers of XPS can use it simply to replace HBCD. Because the thermal stabilizers have already been added in our FR masterbatches. 50%-40% FR content masterbatches with better dispersion are the options.
