UNDERSTANDING FOAMING MECHANISMS

Part 1: July 9th, July 23th
Part 2: July 16th, July 30th

Foaming is a complicated phenomenon in which a significant number of mechanisms play a key role. Nucleation, growing, degeneration mechanisms (coalescence, coarsening, drainage) and stabilization of the cellular structure occur in every foaming process but the way they take place depend on the foaming technology used, the formulation and the processing parameters. In addition, most foaming processes can be considered as “black boxes”, this means that you know the formulation and the processing parameters used and you can characterize the final foam obtained, but there is no experimental information about how the cellular structure and density of the foam are developed. Of course, having a proper understanding of how foaming mechanisms behave in a given process is very helpful to develop foams with tailored cellular structures and properties.

In these two webinars, CellMat Technologies, with more than ten years of experience in this area, will share its knowledge and approaches on this critical topic for foam producers.

The webinar has been divided into two parts:

PART 1: QUALITATIVE AND QUANTITATIVE EVALUATION OF FOAMING MECHANISMS

  • Thursday, July 9th at 10:00 CEST Madrid
  • Thursday, July 23th at 16:00 CEST Madrid

PART 2: EVALUATION OF THE FOAMABILITY AND ITS RELEVANCE IN DIFFERENT FOAMING PROCESSES

  • Thursday, July 16th at 10:00 CEST Madrid
  • Thursday, July 30th at 16:00 CEST Madrid

CHARACTERIZATION OF THE CELLULAR STRUCTURE

The cellular structure of foams plays a crucial role in many properties and, consequently, in many applications of these materials. Thermal conductivity, mechanical properties, surface quality, or acoustic performance, among others, strongly depend on cellular structure characteristics such as average cell size, cell wall thickness, fraction of mass in the struts, gradients in cellular structure, etc. This applies for a wide variety of foams: rigid or flexible polyurethane, extruded or expanded polystyrene, polyolefins, PVC foams, rubber foams, food foams, etc.

However, the accurate characterization of the cellular structure of these materials in a short time is not a simple task.

In these two webinars, CellMat Technologies, with more than twenty years of experience in this area, will share its knowledge and approaches on this critical topic for foam producers and end-users.

The webinar has been divided into two parts:

  • Wednesday, June 24th at 16:00 CEST Madrid

PART 2: ADVANCED CHARACTERIZATION OF THE CELLULAR STRUCTURE USING SEM AND X-RAY TOMOGRAPHY
