A Guelph-based company making products that protect buildings and equipment from environmental damage has partnered with a Brock University chemist to refine critical steps in the manufacturing process.<\/p>\n
Chemistry instructor Paul Zelisko and CSL Silicones Inc. are working together to improve a chemical method involved in the production of the company\u2019s proprietary silicone polymers used to manufacture products that insulate high-voltage insulators.<\/p>\n
Polymers \u2014 large molecules with repeating subunits \u2014 are created through a process called polymerization. The polymerization of silicones needs a substance called an \u201cinitiator\u201d to bring about the chemical formation of long chain species. However, the initiator often creates salts and other by-products that can decrease the quality of the finished silicone polymer.<\/p>\n
\u201cWe\u2019re working with this company to help them advance understanding of how these reactions may work to a commercial advantage,\u201d says Zelisko. \u201cWe\u2019re looking at what kind of initiators and neutralizers can be used in these reactions, what the alternatives might be, determining what happens to that initiator in the system, and how the initiator and any salts can be removed from the reaction system.\u201d<\/p>\n
Zelisko\u2019s research team at Brock includes a postdoc and four undergraduate and graduate students.<\/p>\n
\u201cWe are truly pleased and privileged to have two senior PhD level researchers and the laboratory manager from the partnering company who are coaching, mentoring and engaging students in this project,\u201d he says.<\/p>\n
The Brock team is using specialized equipment and testing methods found within Brock labs, including matrix-assisted laser desorption ionization time-of-flight mass spectrometry, viscometry, a durometer, contact angle micrometer and nuclear magnetic resonance spectroscopy.<\/p>\n
\u201cThe eventual and most significant objective is to develop an initiator that doesn\u2019t create any by-products such as salt or won\u2019t negatively affect the final product if not filtered out,\u201d says CSL Silicones Senior Scientific Researcher Farooq Ahmed.<\/p>\n
\u201cThe industrial research benefit of working along with Dr. Zelisko and his students is truly inspiring, as the limits of their applied science developments are boundary-less,\u201d Ahmed says.<\/p>\n
CSL Silicones Vice-President of Operations Chris McConnery says the research will greatly benefit the company.<\/p>\n
\u201cIt\u2019s a most significant operational cost advantage not having to strip and then filter very, very fine particulates, where shelf life of your end product is dependent on how well you can make it stable by removing by-product in the reaction process,\u201d he says.<\/p>\n
Zelisko began working with CSL Silicones nearly four years ago on a project funded by an Engage Grant from the Natural Sciences and Engineering Research Council of Canada and VIP I grant from the Ontario Centres of Excellence.<\/p>\n
Successes from that first project laid the groundwork for the current research, which began in the fall and was funded in part by Ontario Centres of Excellence, along with CSL as its industry partner.<\/p>\n
\u201cIt\u2019s an exciting partnership,\u201d says Zelisko. \u201cThey\u2019re a wholly-owned Canadian company committed to scientific and applied research, working collaboratively with academia to improve their products, while satisfying their global client\u2019s application needs.\u201d<\/p>\n
The partnership is expected to create two Brock University student co-op positions in manufacturing and scientific research.<\/p>\n","protected":false},"excerpt":{"rendered":"
