Worried about choosing the wrong rubber for food contact products? Using non-food-grade materials can lead to contamination, health risks, and failed compliance tests.
Silicone rubber is the best choice for food safe applications. It is FDA-approved, non-toxic, odorless, tasteless, and can withstand high and low temperatures, making it ideal for direct contact with food.
Clearly understanding which rubber is suitable for food contact applications ensures product safety, regulatory compliance, and long-term performance. Let’s explore the best options and why they matter.
Why Is Silicone Rubber the Best for Food Safe Applications?
Concerned about rubber that might contaminate food? Clearly knowing why silicone is the top choice helps you avoid risks.
Silicone rubber offers excellent safety for food applications because it is inert, non-toxic, BPA-free, and stable across a wide temperature range from -60°C to +230°C. It doesn’t react with food or release harmful substances.
Silicone’s Food Safety Features
Silicone rubber’s properties make it ideal for food contact surfaces:
| Property | Silicone Rubber ✅ |
|---|---|
| FDA & EU Compliance | Certified for food contact |
| Temperature Resistance | -60°C to +230°C |
| Non-Toxic | BPA-free1, no harmful chemicals |
| Odor & Taste Free | Doesn’t affect food flavors |
| Flexibility | Soft, flexible, durable |
| Cleaning & Sterilization | Easy to clean, withstands boiling water |
Silicone is widely used in baking mats, gaskets for food processing machines, kitchen utensils, and seals in beverage equipment.
Is EPDM Rubber Safe for Food Contact Applications?
Need a budget-friendly food safe rubber2? EPDM might be a solution.
EPDM rubber can be formulated to meet FDA standards for food contact. It offers good resistance to water, steam, and some chemicals, making it suitable for seals and gaskets in food processing equipment.
EPDM’s Food Grade Performance
| Property | EPDM Rubber ✅ |
|---|---|
| FDA Compliance3 | Available in food-grade formulations |
| Temperature Resistance | -50°C to +150°C |
| Chemical Resistance | Good (except oils and fats) |
| Water & Steam Resistance | Excellent |
| Odor & Taste Neutral | Good (when properly formulated) |
EPDM is often used in dairy tubing, beverage gaskets, and steam hoses in food plants.
Can NBR (Nitrile) Be Used for Food Safe Applications?
Working with oils and fats in food production? NBR could be the right fit.
NBR rubber can be made food safe and offers excellent resistance to vegetable oils, animal fats, and greases. It’s commonly used for food processing applications involving oily substances.
NBR’s Role in Food Safe Environments
| Property | NBR Rubber ✅ |
|---|---|
| FDA Compliance | Available in food-grade types |
| Oil & Fat Resistance | Excellent |
| Temperature Resistance | -30°C to +120°C |
| Flexibility | Good |
| Cost | More economical |
NBR is often found in food-grade hoses, gloves, and seals in food machinery handling oily or fatty products.
How Does FKM (Viton) Perform in Food Safe Applications?
Handling aggressive chemicals in food processing? FKM might be a necessary option.
Certain grades of FKM (Viton) are FDA compliant and can handle high temperatures and aggressive cleaning chemicals often used in food processing environments.
FKM’s Specialized Use in Food Processing
| Property | FKM (Viton) Rubber ✅ |
|---|---|
| FDA Compliance | Available in select grades |
| Temperature Resistance | -20°C to +250°C |
| Chemical Resistance | Excellent with cleaning agents |
| Oil & Grease Resistance | Excellent |
FKM is typically used in critical sealing applications within food processing machinery where aggressive sanitation processes are common.
Comparison Table of Food Safe Rubbers
Still unsure which food grade rubber to use? This table clearly compares your options.
| Rubber Type | Temperature Range | Key Benefits | Best Use Cases |
|---|---|---|---|
| Silicone ✅ | -60°C to +230°C | High temp, flexible, inert | Baking mats, seals, kitchenware |
| EPDM ✅ | -50°C to +150°C | Water/steam resistant | Dairy tubing, beverage gaskets |
| NBR ✅ | -30°C to +120°C | Oil/fat resistant | Food hoses, seals with oils |
| FKM (Viton) ✅ | -20°C to +250°C | Chemical & heat resistant | Seals in chemical washdown areas |
Clearly choosing the right rubber ensures regulatory compliance and reliable performance in food applications.
What Certifications Should You Look for in Food Safe Rubber?
Worried about passing safety inspections? Certifications matter.
When choosing food safe rubber, ensure it meets FDA 21 CFR 177.2600, EU Regulation (EC) 1935/2004, and NSF 51 standards for food equipment.
Essential Certifications
| Certification | Why It Matters |
|---|---|
| FDA 21 CFR 177.2600 | Ensures U.S. food contact safety |
| EU 1935/2004 | Compliance for Europe |
| NSF 51 | Certification for food equipment |
| BfR | German standards for food contact |
Using certified materials gives you peace of mind and meets legal requirements for food processing and packaging.
Conclusion
Silicone rubber is the best choice for food safe applications due to its superior temperature resistance, flexibility, and regulatory compliance. EPDM, NBR, and FKM also offer excellent alternatives based on your specific needs.
