FR-ZDP
20.5
>350
PBT，PET
Description
FR-ZDP is a white powder, organic zinc phosphinate-based flame retardant. FR-ZDP melts at high temperatures, which is beneficial to the flame retardant and polymers melt-blending process, so that the compounds will not clog the spinnerets.
FR-ZDP is particularly suitable for halogen-free flame retardancy requirements in PET fiber fabrics and PET film systems.
Advantages
High temperature resistance.
No migration.
Good compatibility with the resin.
Typical Properties
| Physical Properties | Unit | Target Value |
| Phosphorus Content | % (w/w) | 20.5 |
| Melting Temperature | ℃ | 210 |
| Bulk Density | g/cm3 | 1.40 |
| Water/Moisture | % (w/w) | 0.3 |
| Decomposition Temperature (at 2% weight loss) | ℃ | 350 |
Usage
Ø In permanent flame-retardant polyester products:
FR-ZDP is suitable for producing polyester chips, filaments, staple fibers, and films. The resulting flame-retardant polyester chips have good color, spinnability, fiber strength, and good dyeability. FR-ZDP has a significant flame-retardant effect, especially for polyester. It is used for injection molding and fiber applications.
Ø In PET:
Adding 3% FR-ZDP, the flame retardant PET compound's limiting oxygen index (LOI) can be more than 30%.
Ø In PBT:
Adding 10% to 15% FR-ZDP and 10% to 15% nitrogen-based flame retardants, such as melamine polyphosphate (MPP) and melamine cyanurate (MCA), the electrical compounds are usually sufficient to obtain the UL 94 V-0 classification at 1.6 and 0.8mm thicknesses.
Packaging & Storage
Packaged in a paper-plastic composite bag and lined with a plastic bag. 25 kg per package.
The product must be sealed, kept dry, dust-free, and cool.
