Description: Polyurethane, like any organic material will burn when exposed to an appropriate ignition source. Flammability of polyurethanes, particularly flexible foam products widely used in home and office furnishings, as well as in the automotive and railway sectors is a subject of great concern to the public opinion and policy makers. This inherent flammability property is closely related to the chemical nature of expanded polymer, being a cellular material with high air permeability and extended inner surface area. There are several reports available in many countries concerning fire statistics related to upholstered furniture which have put into evidence that ignition by cigarettes is one of the primary causes for furniture fire fatalities. Such worrying statistics which showed an increasing trend of fire-related deaths in homes urged several government bodies to take action by introducing at various levels, the so-called Furniture and furnishings (fire safety) regulations for domestic environment and public places. In this scenario, flame-retardant additives have proven very useful to improve the reaction to fire properties of flexible PU foams but recent debate around safety in homes and public places revolves principally around the need for furniture to meet specific fire safety requirements without posing other health risks associated with potential side effects related to smoke toxicity. This KnowHow Webinar is aimed to illustrate the major fire safety measures adopted in various countries to protect the PU foam in order to ensure its safe use in homes and public places and how the selection of the right formulation tool can help to satisfy these requirements.

Description: Polyols are the largest volume raw material used in polyurethanes. Cost and Performance are the two biggest factors for determining the best polyol for a specific polyurethane application. The polyol’s reactivity, based on the position of the OH groups, the ester or ether chemistry, the linearity, and the aromatic vs. aliphatic chemistry all play a part in defining PU properties and performance for a particular polyurethane application. This webinar is designed to provide the polyurethane formulator with a fundamental understanding of how these factors should be considered when formulating polyurethanes from a Structure/Property perspective. The webinar content includes: # Discussions of molecular architecture # Polyol types and their molecular structure : Polyether polyols, Polyester Polyols, Specialty polyols # Advantages and Disadvantages of polyol types # Morphology and molecular motion # Hydrogen bonding within polyurethanes # Discussion of specific polyurethane examples and the measurement of their physical properties

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: Viscoelasticity is a term used to describe materials that exhibit both viscous flow and elastic spring back when a force is applied to them. Viscous flow is a time dependent phenomenon, and an elastic response is instantaneous after a stress has been removed from a material. Viscoelastic materials exhibit both of these properties. The rigid and flexible domains of polyurethanes contribute to their viscoelastic behavior. This webinar is designed to give a fundamental understanding of viscoelasticity as it is related to polyurethane morphology and the isocyanate and polyol building blocks which make up polyurethane polymers.

Description: Polyurethane (PU) foams boost a wide micro and macro morphological properties space which enable its use in a wide swath of applications areas. On the one extreme are the hard and brittle closed fine celled rigid PU foams which are used in a variety of heat management (insulations) applications. On the other extreme are soft open celled flexible PU foams which are used in a variety of comfort applications involving seating, bedding and cushioning. A variety of processes are used to produce these various types of polyurethane foams. Rigid polyurethane foams are typically mostly produced by molding processes, although there are some spray applications as well. Flexible polyurethane foams use a wider variety of applications technologies. The slab-stock foams are typically produced by pouring and reacting mixture on a conveyor system on which a very large bun grows as the foaming system is conveyed down the line. Similarly some viscoelastic or memory foams, as well as some high resiliency (HR) foams used for bedding applications are also produced on conveyor systems. On the other hand, a significant portion of both HR and Viscoelastic foams particularly those used for seating, cushioning and other specialized applications are produced by molding processes. All these types of polyurethane foams can undergo SPLITS (tearing) during or shortly after the manufacturing process. Foam splits result in poor foam performance in their various applications and therefore highly undesirable. In rigid foam used for insulation applications, foam splits result in significant deterioration of the insulating property. For flexible foams, splits result in poor durability and load bearing and comfort properties. The root cause of splits in polyurethane foams and how to eliminate them in the production of these foams will be addressed in this Webinar.

Description: A catalyst is a compound used to affect the rate of a reaction from reactants to final product. Catalysts lower the activation energy required to achieve an excited molecular state, which allows the reaction to proceed more easily and with less energy. The primary job of the catalyst or combination of catalysts in a polyurethane reaction is to control the reaction profile. Polyurethane (PU) catalysts can be generally divided into two types, gelling catalysts and blowing catalysts. Gelling catalysts promote the reaction of the isocyanates with hydroxyl groups, and blowing catalysts are used in polyurethane foam systems and are more selective to catalyzing the reaction of the isocyanate with water to produce foam. This webinar is intended to give a fundamental overview of how PU catalysts work.

Description: Polyurethane surfactants are utilized across a broad range of polyurethane applications including footwear, mattresses foams, automotive interiors, and foam insulation used in refrigerators and construction. The function of a surfactant can be to enhance chemical compatibility of isocyanates and polyols, improve cell nucleation and stabilization and to prevent coalescence. Surfactants work by preserving the thermodynamically unstable state of a foam while it is rising by affecting surface forces until the polyurethane polymerizes far enough to maintain the cell structure. This webinar is intended to give a fundamental overview of how polyurethane surfactants work.
