IntrFace Technologies provides advanced plasma systems designed to treat a wide range of polymers, enabling reliable bonding, coating, printing, and surface preparation across industrial, medical, electronics, and advanced manufacturing applications.
Why Polymers Are Difficult to Bond
Many polymers, especially low surface energy materials, are inherently difficult to bond, coat, or print. Their surfaces often resist wetting, which makes it difficult for adhesives, coatings, inks, and films to form reliable bonds.
Common Polymer Surface Challenges
- Low surface energy on materials such as polyethylene, polypropylene, and PTFE
- Poor wettability and adhesive spread
- Surface contamination from oils, dust, processing residues, or release agents
- Inconsistent bonding, coating, or printing performance
- Need for repeatable surface preparation in production environments
Traditional surface preparation methods such as corona discharge, flame treatment, abrasion, or chemical primers can be inconsistent, difficult to control, or unsuitable for sensitive materials and complex geometries.
How Atmospheric Plasma Treatment Works on Polymers
Atmospheric plasma is a partially ionized gas that interacts with the surface of a material at the molecular level. It modifies only the outermost surface layer, helping improve adhesion and cleanliness while preserving the polymer’s bulk properties.
Key Effects of Plasma Treatment
- Surface Activation: Increases surface energy to improve wetting and adhesion
- Precision Cleaning: Removes organic contaminants and surface residues
- Surface Functionalization: Enhances chemical interaction between the polymer surface and adhesives or coatings
- Controlled Surface Modification: Treats the surface without significantly altering the bulk material
Unlike vacuum plasma systems, atmospheric plasma can operate in open air and may be integrated into manufacturing workflows without requiring vacuum chambers.
