Description
Aluminum diisobutylphosphinate D-13 is made by physical extrusion and is described in the supplied manual as a 1-3 mm irregular granule without a carrier. It is intended for high-temperature polymers such as PA6, PA66, and PPA. The grade melts during processing and is designed to reduce powder handling while retaining the active phosphinate content.

Polyamide Formulation Notes
In company trials, Aluminum diisobutylphosphinate D-13 was evaluated alone and in phosphinate or brominated synergistic systems. Screw configuration, residence time, and front-zone shear affected dispersion. A practical trial should keep the material well mixed before glass fiber is added, then reduce excessive shear in the rear zones to protect mechanical properties.
Company Advantages
Our flame-retardant operation combines manufacturing with application verification. The 5,000-tonne annual line produces powder and granulated forms, and the supporting laboratory checks thermal behavior, particle distribution, and formulation performance. Batch documents and packing labels are reviewed before dispatch, which helps the material supplied for a trial match the grade discussed during technical confirmation.
FAQ
Q: Does the granule contain a polymer carrier?
A: The product information states that D-13 is a physically formed phosphinate granule without added carrier.
Q: Can the same recipe be used for PA6 and PA66?
A: No. Resin grade, glass-fiber content, thickness, and processing temperature require separate confirmation.
Q: How is Aluminum diisobutylphosphinate D-13 packed?
A: The standard information lists 25 kg composite bags with an inner liner.
