Food-Grade Rubber for Food Contact

Food-grade rubber is a material particularly suited to applications in contact with foodstuffs, in particular those containing fats such as milk and dairy products, oils, and vegetable and animal fats. Thanks to its unique properties, food-grade rubber is widely used as a gasket in food-processing plants, ensuring safety and compliance with the strictest food regulations.

Features of food-grade rubber

  • Resistance to Fats and Alcoholic Substances: Food-grade rubber is ideal for contact with foodstuffs containing fats, such as milk, cheeses, and vegetable and animal oils. In addition, it is also particularly suitable for contact with alcoholic substances, such as wine, beer and fruit juices, especially at high temperatures above 100°C. This makes it perfect for use in various food-production processes.
  • Chemical and Environmental Resistance: This rubber offers excellent resistance to ozone, weathering and seawater, ensuring a long service life even in harsh environments. Food-grade rubber also has good resistance to abrasion and UV rays, making it ideal for outdoor applications or in conditions of exposure to intense light sources.
  • Food-Contact Certifications: The food-grade rubber we offer is certified for use in contact with food according to the strictest regulations, including the stringent US F.D.A. (Food and Drug Administration) standard. These certificates ensure that the material is safe for use in direct contact with food, complying with all the required hygiene and safety regulations.
  • Resistance to Extreme Temperatures: Food-grade rubber is particularly suitable in situations where excellent resistance to high or low temperatures is required. This characteristic makes it versatile and suited to various applications, from freezing processes to high-temperature processing.
  • Non-Stick and Stain-Resistant Properties: The rubber is odourless and stain-resistant, characteristics that make it ideal for applications where it is important to maintain the aesthetic and functional integrity of the final product.

Origin and production of natural rubber

In nature, rubber occurs as a colloidal suspension in the latex of certain plants, with the rubber tree (Hevea brasiliensis) as the main source. This plant, native to South America, is now grown in many other tropical regions, including Indonesia, the Malay Peninsula and Sri Lanka. From the latex extracted from this plant, natural rubber is produced, one of the purest forms of natural rubber.

Rubbers obtained from the latex of other plants can contain contaminants and require a refining process before use. For example, gutta-percha and balata, produced by various tropical sapotaceae, are important crude rubbers that must be purified. During the Second World War, other plants such as Parthenium argentatum and Russian dandelion (Taraxacum kok-saghyz) were cultivated to produce rubber in response to the difficulty of accessing Hevea plantations.
