Polytetrafluoroethylene (PTFE) Coated Anti-Dripping Agent

Polytetrafluoroethylene (PTFE) coated anti-dripping agent is specialized polymer that is coated onto the surface of PTFE particles, enhancing its dispersion during the mixing of plastic resins, ensuring uniform distribution throughout the material. The agent is primarily utilized in thermoplastics that necessitate a flame retardant classification of UL V0, such as polycarbonate (PC), acrylonitrile butadiene styrene (ABS), PC/ABS, etc. It plays a crucial role in preventing melting and dripping, while simultaneously improving flame retardant efficacy.

Features

• Exceptional dispersibility and compatibility. The PTFE coated anti-dripping agent demonstrates outstanding dispersibility, ensuring an even distribution within various formulations. Its compatibility with a wide range of materials enhances its applicability across different industries.
• Superior workability. This agent is designed for excellent operability, making it highly user-friendly during processing and application. Its properties allow for seamless integration into production workflows without compromising efficiency.
• Non-agglomeration at ambient temperatures. Unlike some additives, the PTFE-coated anti-dripping agent remains stable and does not form agglomerates at room temperature. This characteristic ensures consistent performance and reliability in various conditions.
• Minimal impact on impact strength. The incorporation of this agent has a negligible effect on the overall impact strength of the final product. This allows us to enhance drip resistance without sacrificing the mechanical properties essential for durability and performance.

Usage

PTFE coated anti-dripping agent can be effectively incorporated into plastic formulations for extrusion granulation. The typical dosage ranges from 0.15% to 0.5%, with the use of twin-screw extrusion generally yielding superior performance compared to single-screw extrusion methods. For specific polymer types, the recommended addition levels are as follows: in PC, the optimal range is between 0.30% and 0.50%; in ABS, it is suggested to use between 0.15% and 0.30%; and in PC/ABS blends, the recommended dosage is from 0.20% to 0.30%.
