Typical Properties

4-Hydroxy-4-isopropoxydiphenylsulfone(D-8) Usage

High-efficiency color developer for thermal recording materials: It is one of the most important BPA-free, eco-friendly bisphenol-based color developers used in modern thermal paper production.

• Alternative to Bisphenol A (BPA): Used to replace traditional Bisphenol A (BPA) and Bisphenol S (BPS), ensuring compliance with international regulations—such as those in the EU—regarding non-toxic, eco-friendly standards for thermal papers used in food-contact applications and POS receipts.
• Thermal paper and label printing: Widely used in fax paper, POS receipts, medical ECG paper, electronic shipping labels, and high-end anti-counterfeiting thermal labels.
• Excellent storage stability: The color-forming product resulting from the reaction with leuco dyes exhibits outstanding heat, humidity, and light resistance; furthermore, its oil resistance and resistance to plasticizer migration are significantly superior to those of traditional color developers, ensuring no fading during long-term storage.

Organic synthesis and polymer modification: Serves as an organic synthesis intermediate for specialty engineering plastics, antioxidants, and specialty UV-curable resins.
