Foams and sheets

Advanced Plasma Surface Treatment for Foams & Sheet Materials​

Unlike thin films, ​foam substrates and rigid sheets​ pose unique challenges due to their thickness (>5mm) and complex morphology (cavities, air inclusions). Our engineers address these by:

​Adjustable Electrode Systems: Customizable discharge gaps (up to 50mm) ensure uniform plasma flux across thick sections.

​Pulsed Atmospheric Plasma: Penetrates cavities without thermal damage, eliminating trapped air that compromises adhesion.

​Material-Specific Protocols: Optimized power (e.g., 10W for polymers, 700W for metals) and gas mixtures (N₂/O₂/He) prevent substrate degradation.

​Why This Matters for Your Application:

​Porous Foams: Plasma functionalizes internal cavity walls, enabling deep-coating adhesion in PU/PI foams used in automotive seals and medical implants.

​Laminated Sheets: Increases peel strength by >40% in aluminum-polymer composites via surface activation prior to bonding.

​Contoured Surfaces: Non-thermal plasma jets treat 3D shapes (e.g., die-cast auto parts) without sacrificial masking.

​Engineering Solutions Include:

▶︎ Cavity-optimized plasma heads for closed-cell foams

▶︎ HV discharge control to prevent arcing in air pockets

▶︎ Real-time impedance monitoring for thickness variations
