Product description FARETARTM BEO is an oligomer synthesized from TBBA (Tetrabromobisphenol A), which has excellent flame retardant effect. It can be divided into EP type and EC type according to different capping group. The former is terminated by epoxy group, and the latter is terminated by tribromophenoxy group. Molecular Structure |
| Chemical Name | Brominated Epoxy Oligomer | Formula | C3H5O(C18H16O3Br4)nC18H15Br4O2 | CAS Number | 68928-70-1 | Molecular Weight | Oligomer | Bromine content (theoretical), % | 53 | Appearance | Light yellow particle | Specific gravity, g/cm3 | 1.8 |
| Comparable grade ICL F-2000 series Characteristics Good electrical properties, UV resistance, thermal stability and aging resistance effect Better adhesion than traditional epoxy resin Excellent self-fire-retardant property No corrosive gas during combustion Application FARETARTM BEO is widely used in the shell of printers, computers, printed circuit boards and electronic components. FARETARTM BEO with high polymerization degree can be used as a flame retardant additive for PBT, PET, PA66 and other engineering plastics; FARETARTM BEO with low polymerization degree can be used as reactive flame retardant to synthesize epoxy resin, phenolic resin, unsaturated polyester, etc.
