Description: Thermoset polymers form the matrix in filled plastics and fiber-reinforced composites used in a diversity of products. These range from consumer items and auto body panels to advanced composites for printed circuit boards, aerospace structural components, and expensive, high-performance sports equipment. Rheological measurements have become the most important characterization technique because of their sensitivity to small changes in structure and the ease to monitor these structural changes. For the thermoset polymers, rheology (including dynamic mechanical analysis) provides details of structural changes, the gel point, and also processing parameters such as viscosity as a function of time. The advantage of the rheological technique is that it allows probing of the sample during the reaction with a small oscillatory deformation, which can generate viscoelastic material properties, such as the storage modulus, the loss modulus, and the tan delta all of which are characteristic of the changes of the material’s structure during cure. The KnowHow Webinar will demonstrate the various applications of the rheological characterization technique in the thermosetting polymer to predict its process behavior and how to evaluating its product performance.
Expert: Dr. Raj Ganesh J. has more than 15 years of experience in the field of polymeric materials characterization techniques and their processing techniques. His major expertise is in the study of structure-property relation of polymeric materials, processing relevant material characterization, material property correlation with the processing behaviours, processing related modelling & simulation techniques. As a qualified Application Expert, he has been providing technical support to various industrial customers from plastics, composites, rubber, and adhesive-related industries in the field of thermal, rheology, and thermophysical property measurements and supporting to resolving the processing related issue by the appropriate material testing solutions. He has conducted several applications-focused technical workshops at various locations in India as well as south-east Asia and, he has participated in various international conferences as a speaker. He has obtained his Master of Science (MS) in Polymer Engineering and Science and Ph.D. in Polymer Processing from the Montanuniversität Leoben (University of Leoben), Austria, Europe. Presently, he is working with TA Instruments, A Division of Waters LLC in India as an Applications Support Manager for the last 9 years.

Description: Cellular materials are solid foams. They are often produced to take advantage of the properties of the solid material whilst at the same time taking advantage of their light-weighting characteristics. The light weight enables their insulation performance since gas is a poorer thermal conductor than solids. This Webinar explores the various technologies for producing cellular plastics (polymeric foams) from various polymer classes. The Webinar will cover aspects of foaming both thermoplastics and thermoset polymers. Thermoplastic polymers are those which are converted to foams starting from fully formed polymers which are processed through softening (melting or devitrification) and then followed by foaming. The end of foaming is accomplished by freezing the cellular structure through recrystallization or vitrification. Thermosetting polymers are those which start from liquid monomeric raw materials which undergo cross-linking chemical reactions to form a solid polymer. The foaming process happens simultaneously with the cross-linking reactions. The KnowHow Webinar will highlight the advantages and disadvantages encountered in foaming thermoplastic and thermoset polymers.
Expert: Dr. Bernard E. Obi is a retired dynamic polymers/materials scientist with extensive expertise in cellular materials in general; but particularly in polyurethane foams processes and applications. He has extensive expertise in both rigid and flexible polyurethane foams. Within the flexible PU foams space, the expertise encompass high resiliency (HR), slab-stock and viscoelastic or memory foams. He earned a Ph.D. in chemical engineering and worked for The Dow Chemical Company from July 1985 to July 2015. Apart from polyurethanes technology; he also has significant expertise in free radical dispersion/suspension polymerization, surface and interfacial science, micro & macro-structure-property-performance relationships, materials development, composites, elastomers and rubbers. He authored a text book on Polymeric Foams Published December 7th 2017 by Elsevier Publishers. Dr. Obi operates his consulting company (PolyFoam Consulting LLC) out of the Houston area in Texas USA, and is engaged in providing consulting services to the polymeric foams industries and businesses.

Description: The Polyolefins (PO) business is a global one, played on a regional scale. POs such as polyethylene (PE) and polypropylene (PP) are the most common plastics. Resin production has moved from the regions where technologies were originated and still continue to be developed, to regions with low cost, abundant raw materials and regions with high demand, but with higher cost raw materials. The total cost of producing POs consists of variable costs and fixed costs. The single largest item is the monomer cost, ranging from 80 to 85% of the total costs. There are several routes to ethylene and propylene, the PO monomers. All modern PO polymerization technologies are capable of producing competitive grades but each generic technology has strengths and limitations. PO resins are sold to tens of thousands of processors throughout the world. They range from large multinationals with the most modern equipment to very small family operations.

Description: Thermosetting polymers are those which start from liquid monomeric raw materials, and undergo cross-linking chemical reactions to form a solid polymer. The foam expansion reaction which is called the blowing reaction is usually relatively very fast. The foam expansion process is typically completed between 60 to 90 seconds in most thermosets foaming processes. The gelling reactions which build polymer structure, hardness and strength takes relatively long time to complete, typically requiring several hours for completion. The purpose of the fast blowing expansion reaction is to minimize drainage which leads to foam instabilities and poor foam quality or in the worse case complete foam collapse. Thus the need to expand quickly has to be balanced with the equal need to polymerize (i.e. gelling reaction) quickly enough to stabilize the foam, whilst not too fast to retard both the foam expansion and cell opening for flexible foams. In addition to the balanced gelling reaction, surface active agents are typically used to provide the complex interfacial phenomena that provide stabilization in foaming processes that begin from the liquid state. The Webinar will highlight the complexities encountered in production of thermosetting polymeric foams, including the role of surface active agents, the balance of blowing-to-gelling reaction to control both polymer and cellular properties.

Description: In contrast to thermosetting foaming processes which start from flowable liquid monomeric components, and end in solid thermoset cellular polymers; thermoplastic foams begin with fully formed polymers. Unlike thermoset polymers whose structures are practically locked-in with covalent cross-links, and therefore not reprocess-able, thermoplastic polymers are those which could be easily reprocessed through softening by applying heat via melting or devitrification. Thermoplastic foaming therefore requires starting with a solid polymer, softening it through melting or devitrification followed by bubble nucleation and foam expansion with both physical and chemical blowing agents that are either dissolved under high pressure or injected into the polymer during foaming process. Surface active agents are not typically required or used in thermoplastic foaming. Extrusion devices that use friction and pressure to melt and dissolve the blowing agents are often used for crystalline polymers. For amorphous polymers which are glassy above ambient temperature, heat is applied to the polymer to devitrify the polymer and then foaming expansion takes place on softening. In both cases, the end of foam expansion is achieved when the solidification is achieved either through recrystallization for crystalline polymers, or vitrification of glassy polymers. The Webinar will fully cover the fundamentals of thermoplastic foaming processes. Some of the contrasting features between thermoplastic and thermoset foaming will also be highlighted.
