| 20120084901 | METHOD FOR PRODUCING A CROSS-LINKED ELASTOMER - The invention relates to method for producing a crosslinked elastomer by radiating a polymer dispersion of at least one crosslinkable polymer with electromagnetic radiation in the ultraviolet (UV light) and/or visible spectral range, wherein the crosslinking is performed in at least two stages as pre-crosslinking and post-crosslinking and at least one photoinitiator is added to the polymer dispersion to trigger the crosslinking reaction prior to the pre-crosslinking. At least one photoinitiator is added once again to the pre-crosslinked polymer dispersion prior to and/or during the post-crosslinking, and the post-crosslinking is also performed with electromagnetic radiation in the ultraviolet (UV light) and/or visible spectral range. | 04-12-2012 |
| 20110289655 | GLOVE - The invention relates to a glove made from a covalently cross-linked elastomer film, which elastomer film contains at least one layered silicate. | 12-01-2011 |
| 20090218192 | HANDRAIL - The invention encompasses a handrail for escalators or moving walkways that includes a grip piece of a thermoplastic elastomer including soft segments and hard segments and optionally a sliding layer arranged on the underside of the grip piece relative to the mounting orientation of the handrail. A ratio of the proportions of the soft segments to the hard segments is selected from a range with a lower limit of 1:1 and an upper limit of 9:1, or, in a variation, from a range with a lower limit of 1.5:1 and an upper limit of 6:1, or, in another variation, from a range with a lower limit of 2.5:1 and an upper limit of 4:1. | 09-03-2009 |
