At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in providing high-quality chemical additives that are crucial for enhancing the safety and performance of manufactured goods. Among our extensive product range, Antimony Trioxide (ATO) holds a prominent position, particularly for its indispensable role in the plastics industry. Its ability to act as a potent flame retardant synergist makes it a cornerstone for creating safer and more durable plastic products.

The incorporation of Antimony Trioxide into various plastic resins such as PVC, polyolefins (like PP and PE), polystyrene (PS), and ABS is a well-established practice. The primary benefit derived from this inclusion is a dramatic improvement in the flame retardancy of the final product. This is achieved through the synergistic interaction between ATO and halogen-containing flame retardants, a combination that is highly effective in disrupting the combustion process. When exposed to heat, this system releases halogenated antimony compounds that act as radical scavengers in the gas phase, interrupting the chain reactions that propagate flames. This mechanism significantly reduces the flammability of the plastic, making it safer for applications where fire resistance is critical.

Beyond just flame suppression, ATO contributes to the overall performance enhancement of plastics. It plays a key role in the formation of a stable char layer on the surface of the material during a fire. This char acts as an insulating barrier, protecting the underlying polymer from heat and oxygen, and preventing the release of flammable volatile gases. This charring effect not only enhances flame retardancy but can also improve the structural integrity of the material under fire conditions. Furthermore, the use of ATO can often achieve desired flame retardant ratings, such as UL94 V-0, with minimal impact on the plastic's mechanical properties, ensuring that product functionality is not compromised for safety.

The industrial grade of Antimony Trioxide, characterized by its high purity, is often preferred for demanding plastic applications. Precise control over particle size is also crucial for achieving optimal dispersion within the polymer matrix, which is essential for maximizing the synergistic flame retardant effect. Manufacturers often employ advanced processing techniques to ensure that ATO is evenly distributed, leading to consistent and reliable flame retardant performance across the entire product.

The demand for Antimony Trioxide in the plastics sector is driven by increasingly stringent fire safety regulations across numerous industries, including electronics, automotive, and construction. Products such as electronic casings, automotive interiors, wire and cable sheathing, and building materials all rely on effective flame retardancy to meet safety standards and protect lives and property. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supplying high-quality Antimony Trioxide that meets these critical industry needs, empowering manufacturers to produce safer, higher-performing plastic products.
