Description:
Due to global warming endangering our planet and growing cost of energy, the thermal insulation materials are gaining more and more importance. Polyurethane foams are one of the best commodity thermal insulation materials and most optimum choice for majority of applications, where heat or cold transfer needs to be significantly reduced. Global production of polyurethane thermal insulation products has been and will be steadily growing. To provide most useful information on specifics of these products, in the webinar we will be talking about: General theory of the heat transfer process; different thermal insulation polyurethane products, their advantages and disadvantages; methods to improve thermal insulation properties of polyurethane materials by optimising their formulations; means to improve thermal insulation capabilities of polyurethane products by applying specific principles to the products’ designing and manufacturing.

Polyisocyanurate foams (PIR) are polyurethane products with exceptional properties. They have excellent fire resistance, superb thermal insulation capability for protection from cold or heat and very good mechanical strength, despite being extremely light. Their mass production is quick and economical. All these make them the best building materials (but not only) in applications where fire safety of people and reduction of energy usage matters. The webinar will present: Properties and main applications of PIR products, basic polyisocyanurate chemistry theory, specifics of PIR formulations and raw materials choices in comparison to standard polyurethane (PUR) technologies, manufacturing equipment for PIR production.

Polyester polyols have several advantages over polyether polyols. They make polyurethane foams with better strength and fire resistance. They are also easier and cheaper to manufacture and manufacturing plants require relatively low investment. All these properties make the polyester polyols the first choice for rigid polyurethane formulations. The webinar will present: • The general chemical structure of polyesters polyols • Their advantages and disadvantages versus polyethers • The types of the polyols and their properties • Raw materials for production of the polyols • Additives improving properties of the polyester based foams • Main principles of polyols manufacturing • Basic setup of a plant for polyester manufacturing

Description:
Moisture cured, one component, reactive polyurethane (PU) adhesives are formulated using an isocyanate and amorphous and crystalline polyols of varying composition which are reacted to form a polyurethane prepolymers. These prepolymers can be liquid or they can be solid at room temperature. If they are solid at room temperature, they are considered reactive hot melt adhesives. All reactive PU adhesives contain residual isocyanate functionality that is reactive with moisture that comes from the atmosphere and/or the surface to be bonded. Reactive PU adhesives contain catalysts to promote the moisture cure and also contain other additives to control rheology, open time and strength of the resulting polyurethane polymer. The choice of polyols, based on performance requirements is an important factor in formulating any polyurethane system. Designing reactive, one component adhesives is no different. Understanding how isocyanate and polyol structure affect reactivity and the physical properties of the formulated adhesive is an important aspect of formulation, which this webinar is intended to provide. The presentation includes: An introduction to adhesive considerations, Comparison of PUR adhesive systems, the chemistry of isocyanates and polyols, Formulating from a Structure / Property perspective, Summary of important concepts

Description:
There is no polyurethane monomer leading to polyurethane polymers. This is in contrast to a polymer like polyethylene which is derived from the polymerization of ethylene monomer and results in a homopolymer of linear or branched structure. Polyurethane polymers result from the addition reactions of isocyanate molecules of different types reacting with active hydrogen functional molecules or polymers that result in phase separated, block copolymers. The size, the shape and the intermolecular interactions of the isocyanates and the polyols used to make polyurethanes affects how phase separated segments will order themselves and how they will move in relation to each other, which will dictate the physical properties of that polyurethane polymer. This webinar is designed to provide an overview of how the selection of isocyanate structure and reactivity, combined with the proper selection of polyols, allows the polyurethane formulator to design and tailor the physical properties of polyurethanes for specific applications.

Description:
Moisture cured, one component, reactive polyurethane (PU) adhesives are formulated using an isocyanate and amorphous and crystalline polyols of varying composition which are reacted to form a polyurethane prepolymers. These prepolymers can be liquid or they can be solid at room temperature. If they are solid at room temperature, they are considered reactive hot melt adhesives. All reactive PU adhesives contain residual isocyanate functionality that is reactive with moisture that comes from the atmosphere and/or the surface to be bonded. Reactive PU adhesives contain catalysts to promote the moisture cure and also contain other additives to control rheology, open time and strength of the resulting polyurethane polymer. The choice of polyols, based on performance requirements is an important factor in formulating any polyurethane system. Designing reactive, one component adhesives is no different. Understanding how isocyanate and polyol structure affect reactivity and the physical properties of the formulated adhesive is an important aspect of formulation, which this webinar is intended to provide. The presentation includes: An introduction to adhesive considerations, Comparison of PUR adhesive systems, the chemistry of isocyanates and polyols, Formulating from a Structure / Property perspective, Summary of important concepts

Description:
There is no polyurethane monomer leading to polyurethane polymers. This is in contrast to a polymer like polyethylene which is derived from the polymerization of ethylene monomer and results in a homopolymer of linear or branched structure. Polyurethane polymers result from the addition reactions of isocyanate molecules of different types reacting with active hydrogen functional molecules or polymers that result in phase separated, block copolymers. The size, the shape and the intermolecular interactions of the isocyanates and the polyols used to make polyurethanes affects how phase separated segments will order themselves and how they will move in relation to each other, which will dictate the physical properties of that polyurethane polymer. This webinar is designed to provide an overview of how the selection of isocyanate structure and reactivity, combined with the proper selection of polyols, allows the polyurethane formulator to design and tailor the physical properties of polyurethanes for specific applications.
