Food Grade Urethane

Food Processing Urethane Products

PSI manufactures FDA approved urethane products for food processing applications. We manufacture urethane rings, gaskets, and custom-molded, FDA-approved items for food processing applications. Chute liners, guides on conveyors, and capper rings for the bottling industry are just some examples of components that are required to be FDA compliant.

There are two different types of FDA material PSI Urethanes produces: FDA Wet and FDA Dry. The reason there are different types is based on the environment they are used in. If a material is used as a guard on a conveyor that carries dry products such as sugar or flour, that would be a FDA Dry application. If it carries fish or other meat products, that would be a FDA Wet application.

More About FDA Regulations on Food Processing Materials

The FDA established the Division of Food Contact Notification and Review within the Office of Food Additive Safety (OFAS), Center for Food Safety and Applied Nutrition (CFSAN), to help ensure components of food contact articles, including food packaging and processing equipment, are safe for their intended use.

The components of the food contact article must be listed within 21 CFR 174 through 179, applicable to the type of substance and intended use. Many polyurethane resins are cleared for use as food contact materials through a number of regulations in 21 CFR, which include specific requirements for the composition of polyurethane resins as well as limitations on their conditions of use.
