Dr. Pieter will be speaking on Wednesday, April 11, 2018 from 9:00am – 9:30am on “How to Boost Silicone Rubber Compounds”.  His presentation will cover how combining quartz flour or ATH with Aktisil Q improves mechanical properties as well as processing without increasing compound cost. Since Aktisil Q is a surface-treated variety of Neuburg Siliceous Earth one would expect increased compound cost, but calculations show that this is not the case.

ChemSpec encourages customers to attend Dr. Pieter’s technical presentation and to stop by our booth #13 at the conference.  The 2018 International Silicone Conference is held at the Sheraton Suites Akron, 1989 Front Street, Cuyahoga Falls, Ohio 44221.
