Sulfur-Free Paper
Sulfur-free paper has high stability due to sulfate-free, which allows products to be better preserved and less prone to deterioration and discoloration due to changes in time and environment.
Sulphur free paper application industries
In the electroplating industry, sulfur-free paper can avoid the chemical reaction between the silver in the electroplated products and the sulfur in the air.
In PCB board industry, sulfur free paper can effectively inhibit the chemical reaction between silver in PCB board and sulfur in the air, and protect the performance of PCB board.
In clothing packaging, sulfur-free paper can be used as a compartment paper, playing the role of moisture-proof and breathable, so that the clothes in the storage and transportation process to maintain a good condition.
In the photovoltaic optics industry, sulfur-free paper plays an important role in the manufacturing, packaging and storage of solar panels and optical components. Solar panels and optics are very delicate and environmentally demanding, and sulfur-free paper can provide a relatively stable and clean environment to protect them from external factors.
