ADP-33P

Product Description

ADP-33P is a halogen-free flame retardant based on organic phosphinates,white powder,called Aluminum Diethyl Phosphinate.The product is not hygroscopic and is insoluble in water and common organic solvents like acetone, dichloromethane, MEK, toluene and so on.

ADP-33P is white granule without carriers by a special process,the bulk density is increased.That can help flame retardant to disperse in the resin,and improve flame retardancy and physical properties of  the product; reduce dust in the process of using.

Benefits

Non-hygroscopic, not hydrolyzed and not precipitated

Suited as flame retardant for thermoplastics and thermosets

High efficiency due to its high phosphorus content

UL 94 V-0 rating down to 0.4 mm thickness

Suited for processing temperatures up to 350 °C

Suitable for both glass fiber reinforced and unreinforced grades

The flame retardant polyamide compounds exhibit very good physical and excellent electrical properties

Suitable for lead free soldering

Good colorability

Non-halogenated flame retardant with favorable environmental and health profile

Applications 

ADP-33P can even be applied in high temperature polyamides because of its high temperature stability. It is suitable for both glass fibre reinforced and unreinforced grades. The flame retardant polyamide compounds exhibit very good physical and electrical properties. 

Processing

Before incorporating ADP-33P, it is important to predry the polymer as usual. Predrying of ADP-33P is not necessary. However, predrying (e. g. 4h at 120 °C) is recommended, if even very low moisture contents must be avoided.  

The mixing and processing methods customary in powder processing of polymers can be used with ADP-33P. 

The optimum conditions for incorporating should be determined in each individual case. Care must be taken to ensure homogeneous dispersion of all components. The temperature of the polymer melt should not exceed 350 °C.

Packaging
25 kg /bag, using paper bags with PE inner.The product should be stored in a dry place at room temperature.
