Safe Chemical Solutions Since 1942

Apex Engineering Products Celebrates 75 Years

75thLogoApex Engineering Products Corporation is celebrating 75 years of safe chemical solutions! Our roots date back to 1942 when Edwin J. Ostermeier serviced boilers on ore boats that canvassed the Great Lakes between the United States and Canada.

Since then our product line has expanded to include RYDLYME Marine and the RYDALL family of biodegradable degreasers, cleaners, odor eliminators and water optimizers. RYDLYME continues to be the “World’s Leading Biodegradable Descaler” with representatives and products in more than 60 countries around the world!

Apex continues to formulate, produce, package and ship products from our warehouse in Aurora, Il. This ensures that customers are receiving quality and consistent products in a timely manner. We strive to keep our customers happy at Apex and this will continue into the next 75 years!

We are proud to be a U.S. manufacturer renowned not only for our biodegradable line of products, but also our in-depth and exceptional customer support. With over seven decades of knowledge and experience in a wide array of applications, our knowledgeable technicians will continue to work closely with you to determine the best solution for your cleaning challenges. We are also an ISO 9001 Certified Company and take great pride in providing the highest level of product and support to our customers…another formula that hasn’t changed since 1942!
