3-A Sanitary Standard Materials

PPE manufactures seals in accordance with 3-A Standard 18-03 “3-A Sanitary Standards for multiple-use rubber and rubber-like materials used as product contact surfaces in dairy equipment”, defining requirements for food quality materials that must also be suitable for cleaning and sanitising solutions.

All PPE’s 3-A Sanitary Standards compliant elastomers are FDA-compliant to FDA CFR21.177.2600, resistant to steam sterilisation, milk fat and water, acid and alkali cleaning solutions and chlorine sanitising solution.

The PPE elastomers meeting the 3-A standard include fluorocarbon, silicone, EPDM and nitrile, allowing manufacturers to select the most appropriate elastomer to temperature, chemical and physical performance criteria.
