RFQ Details

Technical Data
1. Composition of 103

Expandable Polystyrene (EPS) is suspension polymerized from styrene monomer, further more dipped with blowing agent,
molecular formula: (C8H8) n,
Content of Polystyrene: (CAS NO 9003-53-6): 93.2 - 96%
Content of Pentane: (CAS NO 109-66-0) 4 - 6.8%
Hexabromocyclododecane: (CAS NO 3194-55-6) N.D
Content of Flame Retardant: (CAS NO 97416-84-7) ≤1%
REACH Reg. No of Flame Retardant.: 17-***2399-51-0000（Pre-Registration）
2. Characteristics of 103

103 is a high fire-retardant grade product. The application of the block is mainly for construction building; combustion performance is able to reach or equal to the standard of
DIN-4102.
(Environmental, high efficiency; no added of additive such as toluene, dimethylbenzene, and
ethylbenzene; does not contain prohibited substances (HBCD); meets standards of the EU REACH
and ROHS.)
