Product Introduction

ADP diethylaluminum phosphinate is a white, phosphorus-containing, organic aluminum-based flame retardant characterized by high hydrophobicity, excellent thermal stability, and zero migration. It is primarily used in the following applications:

 • Thermoplastic elastomers (TPE), including TPEE and TPU

 • Polyesters, such as PET and PBT

 • Polyamides, including glass fiber-reinforced grades

 • Epoxy resin-based printed circuit boards

This flame retardant delivers outstanding flame-retardant performance, particularly when used in combination with nitrogen-based flame retardants.

All products in the ADP series comply with RoHS directives, are halogen-free, and do not release phosphine (PH₃) gas.

Application

FA-1980 is well-suited for use in PA6 and PA66, offering excellent flame-retardant performance. At a dosage of 10–12%, it enables modified polyamides to achieve a UL94 V-0 rating at thicknesses ranging from 1.6 mm to 0.8 mm.

In halogen-free systems, FA-1980 can also be used in high-temperature polyamides such as PA6T and PPA, achieving a UL94 V-0 rating at a dosage of 12–15%.

 

FA-1980S is particularly suitable for PBT and PET, including both glass fiber-reinforced and

non-reinforced formulations, as well as other nylon engineering plastics.

 

In PBT compounded with 30% glass fiber, dosage is 20%.

 

Package

Packed in paper-plastic composite bags with inner polyethylene liners, 25 kg net per bag. The product must be stored sealed in a dry, dust-free, and cool place.
