Abstract
The invention relates to a press cushion for a one level or multi level heating press including a flat contexture made from threads or fibers; and a silicon elastomeric material made by crosslinking silicon rubber and/or a copolymer made by crosslinking silicon rubber and fluor silicon rubber and/or a copolymer made by crosslinking silicon rubber and fluor rubber. In order to overcome quality issues and to comply with stringent cleanliness requirements when producing circuit boards for electrical applications it is proposed that the silicon elastomeric material and/or the copolymer are addition crosslinked.
