Tetra bromine bisphenol A diether(2,3-dibromo propyl group) |
||
| Chemical name: 1,1'-(Methyl-ethylidenebis[3,5-dibromo-4-(2,3-dibromo-propoxy)]benzene Shortened form: BDDP Structural Formula:  Specifications: - Appearance............................................White or light yellow powder - Melting Point(C)..............................................105-110C - Weight loss..........................................0.3max. - Decomposition Temperature(C).................285min. - Bromine Content(%)..........................................67min. Applications: This product is a high effective fire retardant with both aromatic bromine and aliphatic bromine. It has excellent heat and light stability. Because of its suitable melting point. it can firstly be melted to be uniform dispersion under normal temperature for plastic processing and can be easier to melt and mix with plastic without the phenomenon of substance stratified and separated out. The effect is quite clear when it is used in PP rosin(generally, adding 3-8% fire retardant and 1.5% antimony trioxide into PP rosin can make the product meet the stipulations of UL94-Vo standard. and it is the beast fire retardant for PP rosin) Decabromodipheny ether or pentabromotoluene fire retardant with high melt point can be added into other rosin, such as PE, ABS, and PS, to be the carrier or disintegrating agent for other high melt point fire retardant and stibium oxide. |
