Polyurethanes are defined as those materials possessing urethane groups in the backbone formed by the reaction of an isocyanate and a polyol. Depending on the composition, they can vary from hard and stiff to soft and elastomeric whereas the chemistry favours the production of foamed polymers. Due to the great variety of the components in the polyurethane foam formulation, both, the elasticity of the polymer and the material density can be varied over two orders of magnitude. Because of this unique feature, polyurethane has become the most versatile large volume polymer and found many uses in our daily lives. The main applications of polyurethane are rigid and flexible foam. Rigid foam is mainly used as insulation material, for instance in appliances, whereas flexible foam finds its use in seating applications, bedding and upholstery. Other large volume applications of polyurethanes are in footwear, automotive trim, coatings and adhesives.
The product-processing-properties relationships for rigid and flexible polyurethane foam will be discussed in some detail during the talk.
The BASF Polyurethanes specialised in polyurethane applications and a recognised leader in the polyurethane systems and speciality elastomers business. The European Business unit has a turnover of Euro 2 billion and employs over 1650 people. The headquarter with its global R&D Laboratory is located in Lemförde, a small town in northern Germany. The laboratory is in charge of research for the worldwide PU business and consists of a team of about twenty PhD level scientists. Because of continuous growth there is an opportunity for highly talented scientists with a background in organic or polymer chemistry to start a career in our research laboratories.
The recent innovations of BASF Polyurethanes from sandwich elements with steel/polyurethane/steel to coating for revetments as well as thermal motor encapsulation and special thermoplastic products will be presented.
