  • Composite components on the basis of hydrophobic polyols
    Patent number: 10787550
    Abstract: The present invention relates to the use of hydrophopic polyols for producing fiber composite components on the basis of a polyurethane/polyisocyanurate reaction mixture, to a method for producing composite components and to the composite components as such. The method according to the invention is particularly economical in terms of saving material and time costs and the composite components obtained are characterized by excellent visual and material properties.

  • Process for the production of fibre-reinforced composite parts
    Patent number: 7972676
    Abstract: The invention relates to a process for the production of fiber-reinforced composite components in which an outer film is bonded with a layer containing fiber-reinforced polyurethane, characterised in that a) first an elastic intermediate layer which has a modulus of elasticity of 0.5 MPa to 50 MPa and a thickness of 0.3 mm to 6 mm, is applied to the outer film which has a thickness in the range of 0.2 mm to 5 mm, and then b) at least one other layer is applied to the back of the intermediate layer, at least one layer containing fiber-reinforced polyurethane being applied.

  • Polyurethane elastomers which exhibit improved stability to hydrolysis
    Patent number: 6737471
    Abstract: A solid and/or cellular polyurethane elastomers which are produced using polyester polyols are disclosed. The elastomers which exhibit improved stability to hydrolysis are characterized in that their preparation is carried out in the presence of at least one esters of monobasic carboxylic acid or polybasic carboxylic acids, the (first) dissociation constant (pK) of which is 0.5 to 4.
