Methyl octabromoether can be used as a flame retardant alternative to hexabromocyclododecane for XPS (extruded plastic panels) and EPS (expanded polyethylene).

Chemical name: Tetrabromobisphenol A bis(2,3-dibromo-2-methylpropyl) ether

CAS NO.:97416-84-7

Product use

This product is the main product of the deep processing of tetrabromobisphenol A. The flame retardant effect will be better. It is an additive flame retardant, used for EPS, XPS sheet, flame retardant polyolefin (such as PP, PE, polybutylene, etc.) and thermoplastic high elastomer materials, polypropylene plastic and fiber, polystyrene foam flame retardant, also can be used for polyester fabric flame retardant finishing and vinyl plastic coated double-sided leather flame retardant. It is also suitable for use in polystyrene, unsaturated polyester, polycarbonate, polypropylene, synthetic rubber, etc. It is an excellent alternative to the current flame retardant hexabromocyclododecane.

Product performance

Methyl octabromoether is an additive flame retardant with low dosage, good flame retardant effect and low impact on the physical properties of the material. It is mainly used in EPS, polypropylene and other styrene resins, which can show its good performance. It is a white crystalline powder, soluble in acetone, esters and other organic solvents, and has good stability to heat and ultraviolet light. The product’s flame retardant effect is higher than that of brominated aromatic flame retardants, with good thermal stability, making the processing equipment safe and products with excellent performance, and suitable for higher temperature processing of plastic products.
