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: HR foams have been around for many years , they were however mostly limited for use in high end furniture . This has changed and they are now being increasingly used in foam mattresses as a comfort layer. This webinar will give you an insight on producing it on low pressure continuous foaming machines as well as block foaming machine. It covers an introduction to high resilient foams. The advantages of HR foams as opposed to conventional foams. Chemical packages to manufacture HR foams, Polyols and additives. Machine requirements for manufacturing HR foams. Processing HR foams including machine setup, trough size and fallplate settings. How to adjust the properties of HR foam. Postproduction procedures and curing.
Speaker: Mr. M. A Naqi is Principal consultant and President of LinQ Tech Inc. based in Canada. A graduate in Science I started my career as ‘Production Manager ‘on a continuous Foaming machine at Poly Products LLC (Oman) between 1980 -2001 while directing the company from infancy to market leader in special foams, eventually became CTO in the company. During this period added a molded foam line as well as a rebonded foam line. I have developed formulations for all kinds of special foams, including soft and super soft grades with standard polyol, a unique pre-polymer dispensing system for rebonded foam which preludes cleaning of the pump and pouring tube. Started my own consultation company in 2001 assisting producers in Canada, Middle East and Asia, teaching foam production, adjusting formulations and talking at various shows and been involved in the industry for over 35 years.

Description: 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.

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
