Sulfur-Free Paper for PCB & Solar Protection
Kangchuang Sulfur Free Paper offers chemical-pure, heat-resistant Sulfur-free paper for electronics, PCB manufacturing, and precision metal protection. Reliable and eco-friendly.
High-Quality Sulfur Free Paper – Ideal Protection for Sensitive Metals and Electronic Components
Sulfur Free Paper, also known as sulphur free paper or Sulfur-free paper, is a specially designed functional packaging material that prevents metal surface oxidation. Unlike traditional paper, this Sulfur Free Paper contains extremely low sulfur levels (<50 mg/kg, SGS certified), effectively preventing sulfur from reacting with silver, copper, or other sensitive metals, which could otherwise lead to discoloration, yellowing, or performance degradation. This makes it an essential protective material for electronic components, precision metal parts, and high-end silver products.
Key Advantages of Sulfur Free Paper
1. Extremely Low Sulfur Content
SGS-tested Sulfur Free Paper contains less than 50 mg/kg of sulfur, far below traditional paper standards, ensuring long-term protection without causing metal sulfuration.
2. Prevents Silver Discoloration and Oxidation
Sulfur contamination is a major cause of silver tarnishing and performance decline. Using Sulfur Free Paper packaging significantly extends the appearance and functional lifespan of products.
3. Customizable Grammage and Sizes
Available in weights from 30g to 250g, with fully customizable dimensions, Sulfur Free Paper meets diverse packaging and separation needs.
4. Soft Texture to Protect Precision Surfaces
The paper is soft and smooth, preventing scratches or damage to delicate metal surfaces during packaging and transportation.
5. Supports Bulk Supply and OEM Solutions
We provide long-term, stable supply and can support OEM packaging solutions, enabling personalized branding for customers.
