Abstract: A document feed component is presented comprising a foamed epichlorohydrin elastomer, a curing agent, and a blowing agent, wherein the document feed component has a dynamic coefficient of friction in the range of about 1.0 to about 3.0, a Shore O hardness in the range of about 2 to about 85, a compression set of less than about 12%, and a resistance to wear of less than about 0.05 g/hr. 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 does not require the use of processing aids and migratory additives.
Abstract: Three-phase composite materials system having a low dielectric constant and physico-chemical properties suitable for IC fabrication conditions, and a method for making such materials, are disclosed. The three-phase composite material includes an organic phase, an inorganic phase and a void phase. The organic phase is in the form of an organic polymer matrix, the void phase is represented by microporosity present in the matrix, and the inorganic phase is implemented as inorganic particles that are coupled, via a coupling agent, to the organic matrix. The low dielectric constant of the composite is attributable to the microporous organic polymer matrix. The inorganic particles are responsible, at least in part, for providing thermal stability and other required physico-chemical properties to the composite.
