Frequently Asked Questions

How to choose optical brightener for PVC?

It is worth noting that the same optical brightener may yield different whitening effects in rigid PVC (RPVC) and flexible PVC (FPVC). Bisbenzoxazole or phenyl coumarin group compounds are often used in PVC applications.

What are fluorescent whitening agents?

Fluorescent brighteners, commonly known as white dyes, are colorless organic compounds that emit blue fluorescence under ultraviolet light. They improve the perceived whiteness and gloss of materials by counteracting yellowish tones.
