Understanding Surface Energy: How to Measure and Control the Surface Properties of Thermoplastics to Maximize Adhesion

June 06

The success of bonding and printing to thermoplastics depends on effective control of a remarkably thin zone on the surface of a polymer. Seemingly subtle changes in processing or composition can result in dramatic changes in the surface properties that control adhesion and product quality. This webinar discusses the fundamentals of adhesion and relates this to surface engineering of thermoplastics via techniques such as flame, corona, and plasma treatment. The effects of surface active additives are presented along with techniques for detecting their presence and understanding their effects on adhesion. Practical strategies for process development and process control are presented in a way that provides participants with useful tools for improving product quality and consistency. 

Primary Topics: 
• The nature of thermoplastic surfaces and why understanding and controlling the surface is important for bonding and printing. 
• The fundamentals of adhesion on polymers and how to optimize flame, corona, and plasma treatments. 
• Detecting contaminants on the surface that could be detrimental to adhesion. 
• Useful strategies for process development and process control to improve product quality and consistency.
