Elastomers
Share
Sanitary food process hoses are designed to meet strict hygiene and food safety standards, so they are typically made from elastomers that are FDA (U.S. Food and Drug Administration) compliant and approved for food contact. Some common elastomers used for sanitary food process hoses include:
EPDM (Ethylene Propylene Diene Monomer): EPDM is a synthetic rubber that is widely used in food-grade applications. It has good chemical resistance, high-temperature resistance, and is suitable for both acidic and alkaline food products. EPDM hoses are often used for dairy, beverage, and liquid food product transfer.
Nitrile Rubber (NBR): Nitrile rubber is known for its oil and grease resistance, and it is also used in food process hoses for applications involving fatty foods, oils, and greases. However, it may not be as resistant to certain chemicals as other materials.
Silicone Rubber: Platinum–cure silicone rubber is highly stable and inert, making it an excellent choice for food process hoses. It has a broad temperature range, making it suitable for both hot and cold food processing applications. Silicone hoses are commonly used in baking, confectionery, and pharmaceutical industries.
Natural Rubber (NR): Natural rubber can be used in certain food processing applications, but it has limitations in terms of temperature and chemical resistance. It is more commonly used in non-food industrial applications.
Fluoroelastomers (FKM): Fluoroelastomers, such as Viton, are used when exceptional chemical resistance is required, especially for applications involving aggressive chemicals or high-temperature processing. They are less common in food processing but may be used in specialized cases.
Polytetrafluoroethylene (PTFE): More commonly known as Tufluor or “Teflon”, PTFE is used in extreme cases due to its incredibly inert properties as a thermoplastic. While not as flexible as other elastomers on this list, Tufluor has excellent resistance to high temperatures, mechanical stress, and oxidation.
It's important to note that the choice of elastomer depends on the specific requirements of the food processing application, including the type of food product being handled, temperature conditions, and chemical exposure.
In all cases, the materials used in food process hoses must comply with food safety regulations and standards to ensure that they are safe for contact with food products. Upon request, we can provide information about the materials and compliance of their products to help you choose the appropriate hose for your specific needs.
