Nucleating Agent for High-Gloss Polypropylene

NAP-4 is a substituent sorbitol nucleating agent and used to achieve the balance of gloss, rigidity and impact resistance for polypropylene products.

Property

White powder, insoluble in water or solvents such as methanol, ethanol, acetone, toluene and cyclohexane.

Specifications

ITEM	UNIT	TECHNICAL INDEX
Whiteness	Wr%	≥95.0
Melting Point	℃	≥225
Weight Loss on Heating (105±3℃)	%	≤ 1.0
Bulk Density	g/cm³	0.1～0.3

Application

NAP-4 is widely used in Homo PP, Random CO-PP, and also high molecular weight PE products. Besides improving the balance of gloss, rigidity and HDT performances, it shortens the molding cycle time as well.

Usage

NAP-4 can be fed directly into injection or extrusion; or be supplied by master batches.

Recommended dosage is 0.2～0.3%.

Packaging and Storage

Packed in carton with inner PE bag, 15Kg net each.

Store in cool, dry and ventilated place. Avoid direct exposure to the sun as well as heat source and humidity.
