Description

Antiblaze 19 is a high-performance, halogen-free organophosphorus flame retardant, widely recognized for its excellent thermal stability and compatibility with various polymer matrices. This compound is critical for manufacturers seeking to enhance the fire safety of their products while meeting stringent environmental and regulatory standards. It is an essential additive for industries requiring durable, flame-retardant materials without compromising on mechanical properties or processing characteristics.

Application

• As a primary flame retardant in engineering thermoplastics such as polyamides (PA), polyesters (PBT, PET), and polycarbonates (PC).
• Formulation of flame-retardant polyurethane (PU) foams for construction, automotive, and furniture applications.
• Enhancing the fire resistance of epoxy resins used in electronic encapsulants, adhesives, and composite materials.
• Manufacture of low-smoke, halogen-free wire and cable compounds to meet international safety standards (e.g., IEC, UL).
• Production of flame-retardant textiles and coatings for protective clothing and industrial fabrics.
• Use in thermoplastic elastomers (TPE) and other specialty polymers for consumer electronics and automotive components.

Quality Control

Our Antiblaze 19 is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against comprehensive specifications, including assay, phosphorus content, acidity, and color. Certificates of Analysis (COA) are provided with every shipment, and we can support compliance with relevant industry standards such as REACH and RoHS upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a temperature between 15°C and 25°C (59°F and 77°F). Keep away from strong bases and organic solvents. The product is hygroscopic; ensure containers are kept tightly sealed when not in use to prevent moisture absorption.
