Introduction: Why Compliance Isn’t Optional in Food Equipment

When it comes to food-grade equipment, the margin for error is razor-thin. From sealing gaskets in mixing tanks to insulation in steam ovens, every material must meet the strictest safety standards. Among these critical components, silicone foam cords—specifically food grade, closed cell varieties—play a surprisingly vital role.

Forbest’s Food Grade Silicone Sponge Cord is engineered for this exact purpose—ensuring airtight, hygienic sealing in FDA-compliant environments.

What Is an FDA-Compliant Material?

The U.S. Food and Drug Administration (FDA) outlines specific requirements for elastomers used in food contact applications (per 21 CFR 177.2600). A material is only FDA-compliant if it:

• Doesn’t leach harmful chemicals into food or beverages

• Withstands temperature and pressure in real processing environments

• Resists microbial growth and moisture absorption

Closed cell silicone foam fits the bill thanks to its:

• Low permeability

• Heat resistance up to 230°C (446°F)

• Chemical inertness

Experience from the Field: What Engineers Say

“We used to rely on EPDM in our bottling line seals, but they couldn’t withstand the cleaning cycles. Once we switched to food-grade silicone sponge cords from Forbest, the failures dropped to zero.”
— Tomás Gutierrez, Lead Engineer at a dairy processing facility in Spain

These real-world insights confirm what testing shows—silicone foam cords, when manufactured under controlled conditions, can sustain performance for over 5 years in food-grade environments.

The Science Behind Closed Cell Structure

Unlike open-cell foams, closed cell silicone cords don’t absorb fluids or contaminants. Each microcell is sealed, preventing bacteria from nesting inside.

🔍 Key benefits of closed cell silicone in food sealing:

• No capillary absorption → improved hygiene

• Uniform compressibility → even sealing pressure

• Stable across temperature swings (–60°C to +230°C)

• Retains shape after compression → long-term durability

These features are especially important in equipment that undergoes frequent CIP/SIP (Clean-In-Place / Sterilize-In-Place) procedures.

Expert Commentary

“Silicone’s versatility and compliance record make it one of the few elastomers suitable across all classes of food equipment.”
— Dr. Elisa Navarro, Materials Scientist, European Food Safety Authority (EFSA)

“Closed cell silicone foam cords are now the standard in sealing for CIP-enabled systems due to their structural integrity and resilience.”
— Paul Benson, Senior Consultant, NSF International

Comparison Chart: Silicone vs. Other Materials

Choosing the wrong gasket material may lead to:

• Equipment downtime

• Expensive recall risks

• Non-compliance in audits (FDA, BRC, etc.)

Forbest silicone foam cords are long-life components, designed to reduce your Total Cost of Ownership (TCO).

Conclusion: Future-Proofing Your Food Equipment

In an era of growing regulations and shrinking margins, investing in FDA-compliant, closed cell silicone foam cords is a smart move. With benefits ranging from thermal stability to microbial resistance, they are indispensable for hygiene-critical sealing.
