Product Detail

Surface Modified Nano Al(OH)₃ CAS 21645-51-2 Flame Retardant Masterbatch for PP PE Plastics

Product Overview

Surface Modified Nano Al(OH)₃ (Nano Aluminum Hydroxide, CAS 21645-51-2) adopts special nano crystallization technology and organic surface modification treatment. The surface modifier effectively improves interfacial compatibility between inorganic powder and polyolefin matrix including PP and PE, inhibits particle agglomeration and enhances dispersion in plastic melts. It features endothermic flame retardancy and smoke suppression without halogen release during combustion. It is high-quality halogen-free raw material for manufacturing PP and PE flame retardant masterbatch, as well as direct filling modification of polyolefin products.

Core Features

Organic Surface Modification: Significantly improve compatibility with PP, PE, reduce interfacial defects inside plastics.
Nanoscale Particle Size: Achieve uniform dispersion, minimize negative influence on tensile strength and impact toughness.
Halogen-Free Flame Retardant & Smoke Suppression: Absorb massive heat when decomposed, form protective barrier and lower smoke density.
Good Processing Performance: Smooth extrusion, less screw wear, suitable for twin-screw granulation of flame retardant masterbatch.
Low Impurity & Stable Quality: Low heavy metal content, comply with international environmental protection standards.
Wide Matching Range: Can be compounded with phosphorus flame retardants to achieve higher flame retardant rating.

Product Specifications

Product Name: Surface Modified Nano Aluminum Hydroxide

CAS No: 21645-51-2

Chemical Formula: Al(OH)₃

Appearance: White fine powder

Processing Technology: Nano refinement + organic surface activation treatment

Core Function: Halogen-free flame retardant, smoke suppressant, raw material for flame retardant masterbatch

Applicable Resins: PP, PE, EVA and other polyolefin materials

Application Scope

This surface modified nano Al(OH)₃ is mainly used as core filler for producing PP and PE halogen-free flame retardant masterbatch. Widely applied in plastic injection molding, extruded sheets, plastic pipes, wire sheath materials, plastic packaging and polyolefin modified composites. It can be directly added to polyolefin or used for masterbatch granulation according to production process requirements.

Usage Guide

Add powder together with PP/PE carrier resin, dispersant and auxiliary additives during twin-screw extrusion granulation. Control appropriate processing temperature to avoid premature dehydration of aluminum hydroxide. Adjust filling proportion based on target flame retardant standard. Carry out small batch formulation test before mass production. Keep sealed storage to prevent moisture absorption.

Packaging & Storage

Packaging: 25kg plastic-lined woven bag, customized packaging available

Storage: Store in cool, dry and ventilated warehouse, keep tightly sealed against dampness

Shelf Life: 12 months under original sealed storage

Our Advantages

Our surface modified nano Al(OH)₃ has narrow particle size distribution and stable modification effect among batches. Excellent dispersion in polyolefin systems. Multiple modification schemes can be customized for different masterbatch processes. Factory direct supply ensures stable inventory and timely delivery. Free sample testing and polyolefin flame retardant formulation technical support are provided for plastic and masterbatch manufacturers.
