Abstract
A document feed component is presented comprising a foamed epichlorohydrin elastomer, a curing agent, and a blowing agent. The elastomer optionally further includes activators, polymerization accelerators, and a filler material. An important feature of the present invention is that the use of a foamed epichlorohydrin elastomer in accordance with the present invention does not require the use of processing aids and migratory additives. Consequently, the document feed component of this invention has the advantage of not contaminating paper or other media with which they come into contact, even for extended periods of time, while maintaining other advantageous properties, such as a high coefficient of friction, low hardness, low compression set, and excellent resistance to ultraviolet light and ozone. The document feed component of the present invention may be shaped as a roller, wheel, belt, pad or the like.
