Aluminium Trihydrate (ATH) – Supplier, Manufacturer & Distributor | Plastic & Rubber Grade

Overview

Chemical Bull is a trusted Aluminium Trihydrate (ATH) supplier, manufacturer, and distributor, providing high-performance, fine-grade ATH in bulk to the plastics, rubber, coatings, and electrical cable industries globally.

Aluminium Trihydrate (CAS No. 21645-51-2), also known as Alumina Trihydrate, is the world's most widely used eco-friendly flame retardant and smoke suppressant. As leading Aluminium Trihydrate manufacturers, we supply premium-grade material designed to ensure superior fire safety and thermal stability in demanding industrial applications. ATH works by releasing chemically bound water when exposed to high heat (endothermic reaction), which cools the material and dilutes combustible gases, effectively slowing the spread of fire without releasing toxic fumes.

Applications in Plastic & Rubber Industry

ATH is a multifunctional additive prized for its safety, cost-effectiveness, and low environmental impact.

1. Flame Retardant & Smoke Suppressant

The primary choice for achieving high fire safety ratings in polymer systems.

Applications: PVC cable sheathing, conveyor belts, rubber seals, thermosetting resins (polyester, epoxy), and engineering plastics (PP, PE).
Benefits: Excellent smoke suppression, non-toxic fire retardancy, and low-corrosivity compared to halogenated flame retardants.

2. Filler for Polymer Compounding

Acts as a functional filler that enhances material properties.

Applications: Solid surface materials (artificial marble), industrial coatings, and molded rubber parts.
Benefits: Improves hardness and strength of the final product, provides excellent electrical insulation (anti-arcing), and is chemically inert and non-reactive with most polymers.
