Stainless Steel Interleaving Paper
Product Features
● Clean surface, scratch prevention: Soft and fine texture, no impurities, no dusting, no fluorescence, prevents friction scratches on stainless steel surfaces, ensuring surface finish.
● Anti-adhesion, high-temperature resistance: Suitable for high-temperature processes like stainless steel annealing, heat insulation, no sticking to plates, no paper residue.
● Breathable and moisture-proof: Excellent air permeability, prevents plates from moisture, oxidation, and rust.
● Good toughness: Moderate strength, not easily damaged or torn during use
● Good conformability: High flatness, adheres closely to stainless steel sheets/coils, not easily displaced.
● Low ion extractables, neutral pH: Prevents corrosion of the plate surface by acidic extractables from the paper.
Product Applications
● Specialized interleaving paper for stainless steel hot rolling, cold rolling, and annealing processes, providing high-temperature protection, anti-sticking, and thermal insulation buffering.
● Interleaving paper for storage and transportation of stainless steel coils and sheets, preventing surface scratches, rust, and contamination.
● Protective paper for processing high-end decorative stainless steel, stainless steel for home appliances, and precision stainless steel sheets.
● Interleaving and protective paper for precision metal materials such as aluminum foil and copper foil.

Properties and Technologies
Mechanical Optimization
Tensile strength ≥80N/15mm (longitudinal), ensuring no breakage at high speed winding (maximum line speed 800m/min);
Surface smoothness ≤0.5μm Ra, micron-level contact surface realized by super-calendering process to avoid transferring its own texture to the steel plate;
Elongation control (2-4% longitudinal, 6-8% transverse), matching the elastic modulus of deformation of stainless steel plate.
Chemical Compatibility
pH neutral (6.5-7.5) to avoid acid-base reaction with stainless steel surface passivation film (Cr₂O₃);
Low chloride ion content (≤30ppm) to prevent induced stress corrosion cracking (SCC) of austenitic stainless steel;
Anti-static treatment (surface resistance 10⁶-10⁸Ω), eliminating dust pollution caused by electrostatic adsorption.
