Food-grade silicone provides a healthier, more inert alternative to plastics such as PVC and urethane for use in food and beverage applications. Silicone doesn’t require plasticizers to make it perform elastically, so there is far less leaching of harmful chemicals like BPA into food and liquids, meaning that it preserves customer health without sacrificing the durable properties of rubber. Further, because of the lack of plasticizers, it does not impart taste or odors to the food or beverage that it contacts. Additionally, silicone is resilient and nonporous, and therefore it provides an ideal storage solution.
Vanguard manufactures food-grade silicone using highly precise, cost-efficient processes in our ISO 9001:2015–certified facility. We build silicone products using custom compound formulations and economical in-house operations such as cutting, bonding, and O-ring fabrication.
We use these processes to design multi-lumen silicone products to tight tolerances. These factors and more make us a one-stop shop for those seeking food-grade silicone extrusions and molded products with extensive application engineering support.
FDA Grade/Food Grade Silicone: Common Applications
We design our food grade silicone compounds to conform to 21CFR177.2600, which is the FDA “gold standard” for food contact applications. These products can be used in a wide variety of food processing, packaging, and preparation applications. Because only specific ingredients can be used in food and beverage applications, we make sure to procure raw materials only from the most reliable sources and strictly control the compounding and formulations all within our factory.
FDA grade silicone must be finished in a specialized way so that it doesn’t contaminate items that come into contact with the material. Food-grade silicone must also be able to operate in temperatures ranging from −103°F to 450°F, and it must be a nonmarking material to avoid contaminating products.
Food-grade silicone has a number of essential applications in the food and beverage industry. Some of its most important applications include:
Dairy Transport Tubing
Vanguard has several compounds that have passed requirements required in the most stringent dairy industry standards. These compounds can withstand the daily wear and tear for applications in transporting dairy products and the harsh cleaning chemicals they are exposed to.
High and Low Temperature Silicone Tubing
Silicone’s ability to perform well over a wide temperature range along with its durability and flexibility make it a top material to use when manufacturing high-temperature tubing, which food processors use to dispense and mix food/beverage products. Silicone’s nontoxic qualities as well as its temperature and tear resistance mean that it won’t melt or otherwise contaminate edible products in high-temperature environments. Silicone remains flexible down to -100F, making it ideal for below freezing applications as well.
Commercial Food Equipment Seals And Fluid Transfer
Vanguard has taken the extra step of submitting several formulations to NSF International, the most trusted name in commercial food safety, for their evaluation and certification. NSF International is an accredited, independent organization that tests, audits, and certifies products and systems in food and water processing based on their safety and impact on human health. Currently, Vanguard has 11 compounds which are certified to ANSI/NSF Standard 51 for Food Equipment materials, we more being added.
