Facilities involved with the production of foodstuffs are usually required to use on equipment gaskets and seals that comply with FDA (or similar) requirements for non-toxicity and chemical compatibility. In this blog we highlight the sealing materials which meet requirements issued by the FDA or other bodies, and which should be used to manufacture gaskets and seals for food grade applications.

What makes a gasket material FDA-grade?

The US FDA (and similar regulatory bodies in other jurisdictions) has strict standards and requirements in place for the types of materials that can come into contact with food and other consumables. This means that the materials used to make food grade gasket and seals must be made from ingredients officially approved by the FDA and listed on its so-called “white list” (Part 177: Indirect Food Additives: Polymers). Food grade gaskets and seals must satisfy the following demands:

What FDA-grade materials are used to make food grade gaskets and seals?

The following FDA-grade rubber compounds are used by CRG to fabricate food grade gaskets and seals:

In addition to the above FDA-grade materials, CRG also supplies gaskets and seals made from EPDM certified to the NSF/ANSI 61 standard. These gaskets support potable water applications where the use of high purity, non-toxic gaskets is required.
