Benefits
- High chemical purity: Metal interleave papers enable critical metal processing while protecting the surface from scratches, stains, and tarnishing.
- Surface strength: Steel-Shield® offers pull-resistance and tear properties to help avoid breakage that can result from fast and frequently changing processing speeds. These papers withstand high speed, high tension, temperature variations and slip caused by temperature drop between sheet layers.
- Innovative properties: Metals interleave papers offer specialized treatments for increased oil absorption, high temperature metal processing, tarnish prevention, and electrostatic bonding.
- Environmentally smart: Light-weight options offer higher yield, fewer roll changes, and overall source reduction. Additionally, Ahlstrom’s sustainable trulyNatural® brand of kraft fibers offer superior strength allowing multiple passes through processing equipment.
- Collaborative innovation: Ahlstrom draws on its unique manufacturing capabilities, extensive technical knowledge, and expertise to collaborate with customers to provide innovative, customized solutions for the steel industry.
