Sulfur-Free Protective Paper for LED

Sulfur-free paper contains no sulfur or has extremely low sulfur content, effectively preventing reactions with sulfur vapor in the air to form corrosive substances such as sulfuric acid and protecting sensitive components from erosion. Sulfur is one of the main causes of metal oxidation and discoloration. Compared to ordinary paper, sulfur-free paper maintains stable physical properties in high-temperature environments, making it suitable for high-temperature processes like reflow soldering and encapsulation in LED manufacturing. By isolating sulfur contact, sulfur-free paper significantly extends the shelf life of LED components (such as circuit boards and silver layers), preventing performance degradation due to oxidation. It is not only used in LED packaging layers but also in applications like electronic component storage, food packaging, and medical supplies to meet diverse needs.

Sulfur-free protective paper not only addresses the chemical hazards of sulfur on metal components but also meets the requirements of high-precision manufacturing and long-term storage, serving as a critical safeguard for the reliability and lifespan of LED products.
