OB-1 Optical Brightener High Efficiency Whitening Agent for PE / PVC / ABS Applications

OB-1 Optical Brightener is a high-performance whitening agent designed for PE, PVC, ABS, PC, and other plastic materials. It provides superior brightness and high whiteness, making products visually more attractive while maintaining excellent thermal and weather resistance.

This brightener is a yellow-green powder with HPLC content of 99.1%, ensuring high purity and performance. Its fine particle size allows uniform dispersion in polymer matrices, preventing streaking or uneven coloration. OB-1 is versatile and can be added during polymerization, post-processing, or processed into paste form for textile whitening applications.

Key product characteristics:

• High-efficiency whitening for plastics
• Excellent heat and weather resistance
• Fine particle size and high purity (passes 200 mesh)
• Low dosage with strong adaptability
• Stable ash content (0.21%) and low volatile matter (0.30%)

OB-1 ensures uniform brightness and whiteness in plastics while providing ease of processing and reliable results for industrial applications.

Packing: 25kg/bag
Storage: Conventional storage
Shelf life: 2 years under proper storage conditions
Handling: Store in a cool, dry, and well-ventilated warehouse. Keep away from moisture and direct sunlight. Avoid mixing with strong oxidizing agents or high temperatures that may cause decomposition and gas release.
