In one aspect, the first curing co-agent is represented by the formula CH2═CH—Rf—CH═CH2, wherein Rf is selected from a divalent perfluoroaliphatic group optionally containing one or more O atoms, a perfluoroarylene group, and a perfluoroalkarylene group. In another aspect, the first curing co-agent is selected from the group consisting of an allyl cyanurate, an allyl isocyanurate, a methallyl cyanurate, and a methallyl isocyanurate. In either aspect, the second curing co-agent is an organic compound including at least one terminal alkene, with the proviso that the second curing co-agent is not a member of the group of first curing co-agents. Also provided are the reaction product of these compositions and a method of making an elastomer comprising curing these compositions.

    摘要: A coupling feature for double-walled pipes. A double-walled vent pipe section has an outer wall with corresponding male and female coupling features formed on opposite ends thereof. The inner wall of the double-walled pipe section has a small ridge formed around the circumference of one end. When pipe sections are coupled together, the male and female coupling features on the outer walls engage, and the ridge on the inner wall of one pipe section engages with the bare inner wall of the other pipe section.

    摘要: A venting system and a method for installing the venting system. A non-flexible metallic venting pipe comprises a chase. A first end of the vent pipe is positioned adjacent an appliance installation and a second end positioned at an exit to an external region of a home. A flexible vent tube comprising a sealed non-corrosive material, having a first end and a second end, is positioned between the first end of the venting pipe and the second end of the venting pipe. Adapters are positioned at the ends of the venting pipe. A method comprises routing a flexible venting tube comprising sealed, corrosion resistant venting material through an existing non-flexible double-walled vent comprising non-sealed material.
