Food-grade gasket materials are an essential part of the food industry. They are used to keep contaminants out of food and prevent the spreading of bacteria. There are a variety of materials that can be used for these applications, and each has its advantages and disadvantages.
To ensure that your o-rings and seals meet all food safety standards, it is crucial to select a suitable material. This guide will help you choose the best high-temperature food-grade materials for your application.
What are food-grade gasket, O-rings, and seals made from
There are a variety of materials that can be used for food-grade o-rings and seals, each with its advantages and disadvantages. The most common materials are:
- Fluorocarbon (FKM)
- Nitrile (NBR)
- Ethylene Propylene Diene Monomer (EPDM)
Each material has its benefits and drawbacks that should be considered when selecting.
Fluorocarbon (FKM) is the most common material used in food-grade applications. It has excellent resistance to chemicals and high temperatures and is FDA compliant. Fluorocarbon is a very durable material that is perfect for high-pressure applications. It is not as flexible as other materials, so it cannot be easy to set up.
Nitrile (NBR) is another common material used in food-grade applications. It has good resistance to chemicals and temperatures and is also FDA compliant. Nitrile is less likely to cause an allergic reaction in people sensitive to latex. However, it is not as durable as other materials and can break down over time.
Ethylene Propylene Diene Monomer (EPDM) is a synthetic food-safe rubber often used in food-grade applications. It has excellent resistance to chemicals and temperatures and is FDA compliant. However, it is not as flexible as other materials, making it difficult to install.
Silicone is a type of synthetic food-safe rubber that is often used in food-grade applications. It can be used in hot and cold settings, making it versatile for various industries. However, it cannot be easy to install.
Consider the advantages and drawbacks of each material when selecting a substance, especially if it must be a high-temperature food-grade gasket material. Select the material that best meets the needs of your application.
The benefits of using food-grade O-rings and seals
Processing Magazine states that if you want to seal food properly, you need a material compatible with many different chemicals. This means it needs to withstand the chemicals used in food processing, such as solvents, steam, and amines. The food-grade gaskets need to be able to withstand cleaning procedures and sterilization techniques as well.
There are many benefits to using food-grade gaskets or materials. They can keep contaminants out of food, prevent the spread of bacteria, and are available in various materials to suit your needs. Food-grade o-rings and seals are an essential part of the food industry, and choosing the suitable material is crucial for ensuring safety standards are met.
Food-safe lubricants for use with food-grade O-rings and seals
It is essential to use food-safe oils with food-grade o-rings and seals to prevent contamination. Food-safe lubricants are designed for contact with food and will not cause contamination. There are a variety of food-safe lubricants available, including:
- Silicone Grease
- Teflon Grease
According to Silicone Engineering, food-grade silicone is an excellent implement for food manufacturing, packing, packaging, transport, and storage. Because it doesn’t include any harmful fillers like BPS or BPA, it’s non-toxic and contributes to its food-safe status.
It would help if you regularly inspected your food-grade gaskets and seals for signs of wear or damage. If any damage is found, it is crucial to replace the o-ring or seal immediately. Failure to do so could result in contamination or the spread of bacteria.
Storage and handling of food-grade O-rings and seals
Food-grade o-rings and seals should be stored in a cool, dry place. They should be handled with clean hands and kept away from contaminants. Food-grade seals and o-rings should be stored in a clean, dry container when not in use.
There are a variety of materials that can be used for food-grade gaskets, o-rings, and seals. Each material has its benefits and drawbacks that should be considered when selecting. When choosing a material, it is essential to consider the needs of your application. Food-grade gaskets, o-rings, and seals are a necessary part of the food industry, and choosing the suitable material is crucial for ensuring safety standards are met.
