FDA Silicone

FDA silicone

FDA‑compliant silicone is a high‑purity elastomer formulated to meet the material safety requirements of 21 CFR 177.2600, the U.S. Food & Drug Administration regulation governing rubber articles intended for repeated food contact.

These materials are used in food processing equipment, beverage systems, dairy operations, pharmaceutical manufacturing, and hygienic sealing applications where cleanliness, durability, and regulatory compliance are essential.

SSP manufactures FDA‑compliant silicone materials with tight control over extractables, cure chemistry, and physical properties, ensuring consistent performance in demanding sanitary environments. Keep reading to learn more and contact us for a quote. 

What Makes a Silicone “FDA‑Compliant”?

A silicone elastomer is considered FDA‑compliant when it meets the requirements of 21 CFR 177.2600, which limits:

  • Extractables in water and n‑hexane

  • Volatile content

  • Cure system byproducts

  • Ingredients used in compounding

FDA compliance applies to the material, not the finished part — meaning the silicone formulation must meet the regulation before molding, extrusion, or fabrication.

Key Characteristics of FDA‑Compliant Silicone

  • High‑purity base polymer

  • Platinum‑cure or peroxide‑cure systems suitable for food contact

  • Low extractables and leachables

  • Odorless and tasteless

  • Resistant to cleaning chemicals and sanitizers

  • Wide operating temperature range (–60°C to +200°C typical)

FDA Silicone vs. Medical‑Grade Silicone

These terms are often confused, but they serve different regulatory needs.

FAQs About FDA‑Compliant Silicone

Does FDA silicone require a specific cure system?

Both platinum‑cure and peroxide‑cure systems can be FDA‑compliant, provided they meet extractables limits.

Is FDA silicone safe for repeated food contact?

Yes — 21 CFR 177.2600 specifically covers repeated‑use food contact applications.

Can FDA silicone be used in high‑temperature food processing?

Most FDA silicones operate from –60°C to +200°C, with specialty grades available for higher temperatures.

Is FDA silicone resistant to cleaning chemicals?

Yes — it withstands common sanitizers, detergents, and CIP/SIP processes.

Does FDA compliance apply to the material or the finished part?

Compliance applies to the material formulation, not the final geometry.
