  • Photovoltaic solar module having a polyurethane frame
    Patent number: 8381466
    Abstract: The present invention relates to a photovoltaic solar module, a process for the preparation thereof, and a device for generating electric energy employing such a solar module. The photovoltaic solar module has a wholly or partly surrounding frame of polyurethane which is characterized in that said frame has an elongation at break of at least 50%, a modulus of elasticity of at least 30 N/mm2 and a coefficient of thermal expansion of up to ?=80×10?6/K, the modulus of elasticity and the coefficient of thermal expansion each being measured parallel to the edges of the module.
    Type: Grant
    Filed: March 24, 2009
    Date of Patent: February 26, 2013
    Assignee: Bayer MaterialScience AG
    Inventors: Hubert Ehbing, Frank Schauseil, Andreas Hoffmann, Daniel Seidlitz

  • Method for producing soft to semi-rigid polyurethane integral foamed materials
    Patent number: 6590003
    Abstract: The invention provides a process for the production of flexible to semi-rigid polyurethane shaped articles with a compacted edge zone of given hardness and a significantly more flexible cell core, so-called integral foams, in which non-combustible mixtures of fluoroalkanes which comprise 1,1,1,3,3-pentafluorobutane (R 365mfc) are employed as physical blowing agents.
