Most polymers contain many non-polymeric components intended to stabilize, toughen, color and lubricate the final product. Certain classes of these additives are capable of migrating to the surface. This additive migration can create a surface that has a composition very different from the bulk of the polymer. If the manufacturing process includes an interface between the polymer and an adhesive or paint, or in the case of a medical device, contact with human tissues, additive migration to the surface (blooming) can have serious consequences. Blooming represents a form of contamination that can result in adhesive or paint failures or worse.
This webinar discusses:
- The origins of blooming
- Common additives that are subject to blooming
- Strategies for detecting, controlling, and avoiding issues associated with blooming.
Watch how flame treatment of polymers affects how ready your polymer surface is for additional processing.
When it comes to preparing polymers for painting, printing, coating, sealing or bonding, there’s an optimal level of treatment, and the Surface Analyst shows how overtreatment can negatively affect the surface.
Regardless of industry, whether automotive, aerospace, film & flexible packaging or otherwise, contact us today to discover how to optimize your material system using the Surface Analyst.
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
- The Nature of Thermoplastics and why Understanding and Controlling the Surface is important for Bonding.
- 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.
