New silane minimises ethanol emissions

Wilton, Connecticut - The former GE Advanced Materials business has introduced a silane coupling agent - e-free 189 -that, it claims, produces almost zero ethanol during the silanisation reaction.

Momentive Performance Materials - created from the sale of GE Advanced Materials to Apollo Management, LP in December 2006 -  said it is showing the material initially in the United States, and will roll it out around the world over the coming months. The company is exhibiting at the K fair, in Hall 8a / B47.

Momentive said, "e-free 189 silane may replace traditional mercapto silanes because it does not vulcanise prematurely, making it easier and potentially less costly to use than traditional silanes." It added, "e-free 189 silane may be an excellent candidate to consider for use in the production of virtually any rubber product, including shoe sole compounds, wire and cable products, belts, hoses, grommets, and flooring. It may replace ordinary alkoxy silanes such as ethoxy and methoxy. More effective coupling, higher modulus and tensile strength, and maximum abrasion resistance may be achieved in the physical properties of rubber products created with e-free 189 silane. In testing a simplified shoe sole compound, e-free 189 silane delivered a greater than 20 percent improvement in reinforcement as well as excellent hardness and elongation."
