Composite tanks pass migration test

1 min read

Brazilian composite manufacturer Tecniplas says that it has received certification regarding the migration of substances in its composite tanks.

In tests, the company met the maximum limits for total and specific migration, Tecniplas said.

The certification covers tanks and equipment made with orthophthalic and isophthalic polyester resins and vinyl ester epoxy resins. They incorporate an internal surface liner that prevents the formation of incrustations, making cleaning easier.

As well as water, soft drinks and juices, oils and fats (butter and margarine), cereals and flours, dairy products and sauces, Tecniplas' tanks and equipment can store and participate in the processing of alcoholic beverages in concentrations below 5%, such as vinegar, cider and beer, and higher than 5%, including wines and liqueurs.

“The specific migration test quantifies the migration of substances presented on Brazilian Health Regulatory Agency (ANVISA) positive lists, that is, of elements that must meet the requirements of dispersion limits after the tests,” said Luís Gustavo Rossi, director of Tecniplas. “With these two certifications, we guarantee even more security for operators and end users of our products.”

“[Composite tanks] are monolithic, that is, manufactured in a single piece,” he added. “This means that there are no soldering points, areas normally subject to leaks.”
