Sulfur Free Paper Manufacturer & Supplier
Sulfur-free paper is mainly used in the electronics field, such as packaging for PCBs (printed circuit boards) and silver-plated products, including circuit boards, wiring boards, hardware terminals, etc.
Description
Sulfur-free paper is a special type of paper with a neutral pH value. It is white in color, has a smooth and delicate surface, and features high surface tension after special treatment, making it less likely to produce paper debris. Sulfur-free paper is mainly used in the electronics field, such as packaging for PCBs (printed circuit boards) and silver-plated products, including circuit boards, wiring boards, hardware terminals, etc. It can effectively prevent the silver in electroplated finished products from undergoing a chemical reaction with sulfur in the air, which causes product yellowing. Therefore, it is necessary to use sulfur-free paper for packaging as soon as the product is completed to ensure product quality. In addition, sulfur-free paper can also be used to protect food products. We can also perform slitting according to customer needs and provide various specifications, such as small wound rolls, cut flat sheets, and slitted paper tapes. Whether for special use in PCBs or other purposes, we can meet requirements for different sizes and grammages.
Choosing our sulfur-free paper means choosing comprehensive protection for electroplated products!

Sulfur-Free Paper for PCB
During the production and transfer process of PCBs, such as moving from one link of the production line to another, or during temporary storage and transfer, sulfur-free paper can separate the PCBs, preventing their surfaces from coming into direct contact with other objects, avoiding scratches and abrasions, and protecting the circuits, soldering points, and various coatings on the PCB surface.
Sulfur-Free Paper for Precision Electronic Components
Modern electronic components with gold, silver, copper and other metal conductors and contact points are very sensitive to sulfidation and oxidation reactions. The formation of sulfides and oxides increases contact resistance, affecting the performance and lifespan of electronic components. Sulfur-free paper as packaging material provides a sulfur-free, low-acid storage environment for electronic components, extending their service life.
