BIOPOLYMERS AS A PROMISING OPTION TOWARDS MORE SUSTAINABLE FOAMS
SPEAKER/S: ALBERTO LOPEZ-GIL
DESCRIPTION: Biopolymers are considered one of the most attractive approaches to tackle the environmental concerns associated with plastics, such as littering in natural ecosystems and the shortage of space in landfills. The same problem is linked to foamed products obtained from fossil-based polymers, not only those used for foamed packaging products but also those used in longer-term applications, such as in thermal insulation or car parts. In all these applications the use of biobased polymers also provides a lower carbon footprint.  However, biopolymers often lack the required features needed in a polymer to obtain a good foam: absence of melt strength, low thermal resistance, and poor mechanical performance, to name a few. This is why the foam market is wondering if biopolymers can be considered as a real option to obtain more sustainable foamed products with similar structures and properties to the ones already obtained using fossil-based polymers.

NOVEL APPROACHES TO CONTROL DENSITY AND STRUCTURE IN RUBBER FOAMS
SPEAKER/S: ALBERTO LOPEZ-GIL
DESCRIPTION: Rubbers or elastomers are polymers with outstanding properties, such as high elasticity, thermal resistance, and abrasion resistance, among others, which make them widely used in several applications such as tires, gloves, footwear, seals, hoses, belts, adhesives, to name a few. The combination of the properties inherently linked to elastomers with those typically found in foams, such as low density, thermal insulation, acoustic absorption, buoyancy, energy absorption and so on, turn elastomeric or rubber foams into a very attractive and versatile materials, which are nowadays used in several sectors and applications. However, their extremely low glass transition temperature, low modulus, the need for crosslinking and the inherent shrinkage phenomena, make it a foaming system challenging to control.

STRATEGIES TO FACE THE CURRENT CHALLENGES IN THE PRODUCTION OF POLYMER FOAMS BY EXTRUSION FOAMING
SPEAKER/S: VICTORIA BERNARDO-GARCIA
DESCRIPTION: Extrusion foaming is a continuous, quick, simple, and versatile technique to fabricate foamed products at industrial scale. Among others, extrusion foaming allows the production of foamed tubes, pipes, frames, or sheets from a large variety of polymer matrices. This technology can be applied to the production of both high and low-density foamed parts.

REDUCING THE THERMAL CONDUCTIVITY OF POLYMERIC FOAMS – METHODOLOGY & CASE STUDIES
SPEAKER/S: CRISTINA SAIZ-ARROYO
DESCRIPTION: One of the main applications of low-density polymeric foams is thermal insulation. The inclusion of a gaseous phase is accompanied by a strong reduction of thermal conductivity that makes these materials ideal candidates to be employed as thermal insulating materials in many different applications. Several facts are boosting the development of thermal insulating materials with lower thermal conductivities and consequently, with improved insulating efficiencies. Thus, it is becoming more and more important reaching quantifiable reductions in the thermal conductivity values to obtain insulating materials with advanced characteristics.

EXPERIMENTAL TECHNIQUES TO EVALUATE THE FOAMING KINETICS OF PU FOAMS
SPEAKER/S: MIGUEL ANGEL RODRIGUEZ-PEREZ
DESCRIPTION: In this second part of the webinar, different approximations are considered to evaluate and understand how the changes in the formulation affects the reaction kinetics and foaming mechanisms (nucleation, coalescence, coarsening and drainage) of PU foams. It is also explained how the information obtained from this detailed analysis of the reaction kinetics can be used to develop foams with improved properties.
