III. Plastic Additives Series: 1. Nylon Synergistic Flame Retardants FL-100, FL-101: Primarily used in flame retardant formulations to replace expensive antimony trioxide, offering a more environmentally friendly and effective solution to improve material comparative tracking index (CTI) and glow-wire ignition temperature (GWIT); 2. Organic Copper Salt Thermal Stabilizer KL-36: Reacts and chelates with amide groups to protect them from thermal oxidation and other reactive groups in long-term UV and thermal-oxidative environments, preventing molecular chain breakage and degradation; 3. Nylon Nucleating Agent KL-102: Significantly enhances the crystallization nucleation of polyamide, enabling faster demolding, avoiding sticking, shortening the molding cycle by at least 20%, improving product warpage deformation, and increasing product yield and transparency; 4. Nylon Chain Scission Agent HL-10: Effectively reduces material viscosity, significantly improves melt flow index and dispersion, enhances surface gloss, prevents glass fiber exposure, and improves welding, electroplating, and spraying performance; 5. PPO Compatibilizer CX-1: Effectively improves the compatibility and dispersion of nylon and PPO, significantly enhancing the tensile strength and elongation at break of modified materials, especially in long glass fiber products, making it a highly effective modifier; 6. Nylon Anti-Glass Fiber Exposure Agent KL-140: Used as a brightener and anti-glass fiber exposure agent for high and long glass fiber reinforced nylon; 7. Nylon Anti-Ethylene Glycol Hydrolysis Agent KL-37: Developed specifically to meet the Volkswagen TL52062 test standard for antifreeze resistance, particularly suitable for PA66GF30 applications in automotive radiator tanks, tees, and other ethylene glycol-resistant components. Group Vision Yongjiu Group emphasizes technological R&D, collaborating with renowned domestic universities and research institutions to continuously improve product quality and develop new materials.
