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 


Ÿ   High temperature resistance.

Ÿ   No migration.

Ÿ   Good compatibility with the resin.

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

Ÿ   Packaged in a paper-plastic composite bag and lined with a plastic bag. 25 kg per package.

Ÿ   The product must be sealed, kept dry, dust-free, and cool.
