Products Features
- High whitening efficiency; ideal whiteness can be achieved with minimal addition, reducing production costs.
- Excellent compatibility with various polymers, uniform dispersion, no white spots, and no precipitation.
- Resistant to UV rays and aging, extending the product's lifespan and suitable for outdoor products.
- At extremely low addition levels (typically 0.01%-0.05%), yellowish light can be significantly eliminated, achieving a pure whiteness with a bluish-white hue.
- It exhibits excellent solubility and dispersibility in flexible PVC, polystyrene (PS), ABS, polyolefins (PE/PP), and polyurethane (TPU).
Application Fields
- Suitable for flexible PVC, polystyrene (PS), ABS resin, polyethylene (PE), polypropylene (PP), and engineering plastics. Whether transparent or solid colored, it significantly enhances the whiteness and vibrancy of the product.
- For the TPU film, footwear, and cable industries, our OB whitening agent has excellent migration resistance, is not prone to precipitation with long-term use, and maintains a smooth and bright surface.
- Suitable for polyurethane (PU) coatings, baking varnishes, and screen printing inks. Effectively improves coating whiteness and weather resistance, making it particularly suitable for high-demand applications such as white goods and automotive interiors.
- Adding OB fluorescent whitening agent during the spinning process of polyester (PET) and nylon (PA) fibers can give the fabric a brighter color.
