Products Features
- Excellent heat resistance: It can withstand extreme processing temperatures of 350℃-380℃ and remains stable in high-temperature processes such as PET extrusion, nylon injection molding, and PC molding, without decomposition or yellowing.
- High purity and low volatility: Purity ≥99.5%, volatile matter ≤0.3%, effectively reducing carbon buildup on the die head and scale buildup on equipment, extending continuous production cycles, and reducing maintenance costs.
- Highly effective whitening and brightening: Significantly improves product whiteness and enhances color vibrancy even at extremely low addition levels (0.005%-0.03%), making it particularly suitable for white and light-colored products.
- Excellent chemical stability: Resistant to acids, alkalis, and oxidation; maintains long-term stability in engineering plastic systems; does not easily migrate or precipitate, ensuring the product's lasting bright white color.
- Good compatibility: It exhibits excellent solubility and dispersibility in polar polymers such as PET, PBT, nylon, and PC.
Application Fields
- Plastics processing: Suitable for high-temperature processed plastics such as PP, PE, ABS, PS, and PA, improving the whiteness of injection molded parts, films, sheets, and pipes, and enhancing their weather resistance and aging resistance.
- Color masterbatch industry: A core additive specifically designed for whitening masterbatches, ensuring uniform dispersion, excellent compatibility, and no impact on masterbatch stability.
- Chemical fiber spinning: Used in the spinning of polyester, nylon and other chemical fibers to improve fiber whiteness and luster, and is suitable for high-temperature spinning processes.
- Engineering plastics: Suitable for high-temperature engineering plastic modification, does not decompose or discolor, ensuring product performance and appearance.
