Food Grade Polyurethane Parts
PSI manufactures FDA compliant cast urethane products for food processing applications. We manufacture urethane rings, gaskets, and custom-molded, food grade polyurethane parts 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.
FDA Dry Food Approved Products
- Available in multiple shore A durometers (hardness)
- Colors: black, blue, dark blue, green, natural, peach, red, and white.
PSI certifies that all components used to produce your product are acceptable under:
CFR 21-177.1680 “Indirect food additives” – Intended for use in contact with bulk quantities of dry food that do not have free surface fats or oils: Polymers for 20 Shore A through 90 Shore A durometers (hardness)
FDA Wet Food Approved Products
- Available in multiple shore A durometers (hardness)
- Color: black, blue, dark blue, green, natural, peach, red, and white.
PSI certifies that all components used to produce your products are acceptable under:
CFR 21-177.2600 “Indirect food additives” – Aqueous food – Articles intended for repeated use in contact with food.
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. 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.
