  • Splitting of thick hard-foam plates
    Patent number: 10556357
    Abstract: The present invention relates to a method for cutting rigid foams, especially slabstock P(M)I foams. A method is provided here, by means of which it is possible to cut these rigid foams even in relatively high layer thicknesses of, for example, more than 3 mm, without material loss, which is produced in relevant amounts, for example, in the course of sawing as a result of the sawdust formed.
    Type: Grant
    Filed: November 3, 2015
    Date of Patent: February 11, 2020
    Assignee: Evonik Roehm GmbH
    Inventors: Thomas Richter, Kay Bernhard, Florian Becker, Felix Goldmann, Tim Denk, Ulrich Schmidt, Mathias Hempler

  • PMI foams with improved mechanical properties, in particular with increased elongation at tear
    Patent number: 9212269
    Abstract: The invention relates to compounds for producing polymethacrylimide foam materials (PMI foams) with particularly good mechanical properties, in particular with a particularly advantageous elongation at tear. The invention further relates to methods for producing, processing, and using said foam materials. In particular, the invention relates to novel materials, the propensity of which to form tears is clearly reduced in comparison to the prior art. This is tantamount to an elongation at tear that is higher in comparison to the prior art.

    Date of Patent: December 15, 2015
    Assignee: Evonik Roehm GmbH
    Inventors: Kay Bernhard, Mathias Hempler, Werner Geyer, Thomas Barthel, Torsten Jahn
  • POLYMETHACRYLIMIDE FOAMS HAVING A REDUCED RESIDUAL MONOMER CONTENT, AND PRODUCTION METHOD
    Publication number: 20130281561
    Abstract: The invention relates to a process for producing poly(meth)acrylimide foams and also blocks, sheets and the like composed of such poly(meth)acrylimide foams and also the intermediate articles formed from the copolymer of (meth)acrylic acid and (meth)acrylonitrile, which are all distinguished by a particularly low residual monomer content.
