Custom Manufacturing & Surface Treatment Services
 

To optimize compatibility between our inorganic filler and your organic polymer matrix, we offer comprehensive tailoring options:

Precise Particle Size Distribution (PSD

Custom D50 adjustments to fit your exact compound extrusion requirements.

Surface-Treated Aluminum Hydroxide

Coating with Silane, Titanate, or Stearic Acid to reduce oil absorption and improve dispersion.

Whiteness & Moisture Control

Tailored processing for high-end optical or aesthetic applications.

Flexible Branding

OEM production and private label packaging tailored to your regional marketing needs.

 

Super Fine Aluminum Hydroxide

 

Synergistic Retardant Combos (Cost & Performance Optimization)

To reduce total mineral loading and maintain structural integrity in premium polymer alloys, our Aluminum Hydroxide works exceptionally well in synergy with:


Antimony Trioxide (Sb₂O₃): Outstanding synergist for PVC and chlorinated polymers, allowing a 15% reduction in total ATH loading.

 

Zinc Borate: Replaces 5%–10% of ATH to provide excellent anti-dripping (UL94 V-0 compliance) and enhanced char-forming properties.

 

Melamine Polyphosphate (MPP): Creates an outstanding intumescent flame retardant (IFR) phase transition in Polyamide (Nylon) compounds.

 

 

Advanced Quality Control & Testing

From incoming raw materials to finished products, each batch undergoes comprehensive inspection to ensure stable physical and chemical properties before shipment.


Our laboratory is equipped with advanced analytical instruments, including:

  • ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometer) for precise elemental analysis
  • Scanning Electron Microscope (SEM) for particle morphology observation
  • BET Surface Area Analyzer for surface area measurement
  • Laser Particle Size Analyzer for accurate particle size distribution testing
  • Thermal Analyzer for evaluating thermal decomposition characteristics

FAQ

 

Q: What is the shelf life and ideal storage condition for your powder?

A: The shelf life is 24 months from the production date. It should be stored in a cool, dry, and well-ventilated warehouse. Keep pallets sealed until use to prevent ambient moisture absorption.

Q: Do you accept third-party inspections before shipment?

A: Yes. We fully welcome and cooperate with international third-party inspection agencies such as SGS, BV, or Intertek for pre-shipment quantity and quality verification at the buyer's cost.

Q: Are your aluminum hydroxide grades compatible with liquid feeding systems?

A: Yes. Our coarser grades (such as AH-101 and AH-008) feature excellent flowability and low oil absorption, making them ideal for automatic pneumatic discharging and liquid dosing systems.

Q: Can your products withstand high-temperature plastic extrusion?

A: Our standard aluminum hydroxide remains thermally stable up to 200°C, which covers most PVC, PP, PE, and silicone rubber processing temperatures before initial decomposition begins.

Q: What are your accepted payment terms for international orders?

A: We generally accept T/T (Telegraphic Transfer) and Irrevocable L/C at sight. For long-term strategic partners with excellent credit records, flexible credit terms can be discussed.

Q: What industries commonly use your aluminum hydroxide?

A: Our ATH is widely used in flame retardant plastics, wire and cable compounds, silicone rubber, artificial marble, coatings, and ceramics.
