application
1. brominated epoxy resins are usually divided into low, medium and high molecular weight by molecular weight. Low molecular weight is suitable for flame retardant ABS and HIPS, and high molecular weight is suitable for ABS/PC polymer, PBT and nylon 6, 66.
The 2. brominated epoxy resin is also divided into type EP and EC based on the different end groups. Compared with the EC type, the EP type has better light resistance, but the bromine content is slightly lower, while the flame retardant ABS and HIPS have better impact strength.
3. molecular weight ranges from 700 to 45000. Resins with various molecular weights affect the physical properties, heat resistance and impact resistance of flame-retardant plastics. Therefore, appropriate molecular weight can be selected according to the requirements of different flame retardants.
4. 12004000 type EC for ABS and PP resin.
5. 800025000EP type for PBT and PET.
6. 15000-50000EC is suitable for nylon 6, 66.
