Sulphur Free Paper for PCB and Precision Component Packaging
Sulfur-Free Paper is a specialized industrial paper designed for the electronics, precision metal, PCB, electroplating, and optical industries. It is completely free of sulfur compounds, pH-neutral, and non-corrosive, effectively preventing metal oxidation, coating discoloration, and deterioration of sensitive electronic components.
Description
1.Product Overview
Sulfur-Free Paper (also known as Sulphur Free Paper) is a specialty industrial paper designed for corrosion-sensitive applications. It is manufactured using a sulfur-controlled pulping process and neutral chemical treatment, ensuring the material contains no sulfur, acid, or alkaline residues.
This paper provides excellent protection for PCB boards, electronic components, silver-plated parts, and precision metal devices, preventing surface oxidation, yellowing, and corrosion during storage or shipment.
2. Key Features & Benefits
