This year, Tire Tech will celebrate it’s 20 year anniversary in Hannover Germany on February 25-27, 2020. Tire Tech Expo 2020 is the tire industry’s premier conference. Meet Momentive at booth C320 to discuss our innovative technologies.
Unprecedented Performance: That’s the NXT* Z* 45 silane difference.
As a revolutionary mercaptan silane, NXT Z 45 silane offers great advancement in tire performance capability. The incorporation of this silane can dramatically improve the dynamic and physical properties of tires for unprecedented performance.
Tire manufacturers can benefit greatly from our technology in the development of tires for today and tomorrow, that can meet the latest emissions and tire regulations, as well as for electric vehicles in the e-mobility market.
Not only can NXT silane enable better tire performance, it can also help accelerate manufacturing by allowing the production of more stable compounds, and thus enabling more predictable processing, better mixing, and improved milling for smoother sheet appearance.
NXT Z 45 silane enables improved silica – polymer interaction, to allow the production of tires with better overall performance. In addition to advanced tire performance, it can allow processing that is virtually ethanol emission free.
With increasing global demand for high performance tires, Momentive is well positioned to meet your global supply needs. With an increased global footprint, our new Leverkusen, Germany plant allows Momentive to double its NXT silane capacity, and thus serve customer needs from virtually anywhere in the world. Additionally, our new tire application lab in Charlotte, NC lets us expand our technical expertise and broaden our support to you.
ABSTRACT: Controlling the dispersion of precipitated silica into a rubber compound matrix is a significant challenge for achieving the consistent mechanical property improvements that are characteristic of polymer nanocomposites, as inorganic silica aggregates are generally immiscible with the organic elastomeric phase. To prevent silica flocculation, the silica surface is hydrophobized by grafting amphiphilic silane molecules such as 3-Octanoylthio-1-propyltriethoxy silane (OPTES), a blocked mercapto silane trademarked NXT* silane by Momentive Performance Materials Inc.
This approach has been successful for silica dispersion. However, the silica aggregates exhibit self-assembly into highly anisotropic structures depending on the amount of grafted silane per square nanometer of silica surface area, which directly affects the mechanical properties of the rubber. Simulations suggest that this self-assembly reflects a balance between the energy gained when the polar silica aggregates re-flocculate and the entropy of distorting the grafted silane molecules. Both simulation and experimentation demonstrate that considerable control of filler morphology within the polymer matrix is possible through targeted silanization, resulting in enhanced mechanical properties of silica-filled rubber.
