- Baking mats and conveyor belt covers
- Pharmaceutical seals and diaphragms
- Cleanroom barriers
FDA Food Grade Silicone Rolls
For high-volume production, continuous rolls of FDA approved silicone are preferred. Rolls offer:
- Processing efficiency: Master rolls can be slit to width and laminated with pressure-sensitive adhesives (PSAs).
- Consistency: Continuous rolls reduce waste and improve throughput in automated manufacturing.
Applications for these continuous silicone rolls include:
- Conveyor belt linings
- Large-scale gasketing operations
- Industrial food processing systems
FDA Food Grade Silicone Compound
FDA food grade silicone compound provides engineers with design flexibility. These materials are:
- Catalyzed and ready for processing
- Suitable for molding, calendering, and extrusion
- Compatible with robotic dispensing systems
Uncured silicone compound allows engineers to create custom geometries and integrate silicone into complex assemblies. Applications include:
- Tubing and extrusions for beverage systems
- Molded seals and diaphragms
- Coatings for substrates requiring food-safe barriers
How to Select the Right Durometer
Durometer (hardness) is a critical property during material selection. ElastaPro offers FDA food grade silicone in durometers from 10 to 80 Shore A.
- 10 Shore A: Extremely soft, flexible, and compressible
- 30–50 Shore A: Balanced flexibility and strength, ideal for seals and gaskets
- 70–80 Shore A: Rigid and durable, suitable for structural applications
Consider the following during material selection.
- Softer grades are better for dynamic seals requiring flexibility.
- Harder grades provide rigidity and wear resistance.
- Matching durometer to application ensures optimal performance and longevity.
How to Select the Right Color
Color is about more than aesthetics. It can also serve functional and compliance purposes. ElastaPro offers the following colors.
- White and translucent: Most popular for hygienic environments
- Red, green, blue, gray: Used for color coding, product differentiation, or visibility in processing lines
- Custom color matching: Available to align with product branding or system requirements
Applications for various silicone colors include:
- Color-coded gaskets for quick identification
- Visible seals in food processing equipment
- Custom branding in consumer-facing products
FDA Food Grade Rubber FAQs
What Is FDA Silicone Rubber?
FDA silicone rubber is a high‑purity elastomer formulated to comply with FDA 21 CFR 177.2600. This regulation defines what ingredients, extractables, and performance characteristics are acceptable for materials that come into contact with food. FDA silicone rubber is engineered to be:
- Non‑toxic and non‑reactive
- Odorless and tasteless
- Stable across wide temperature ranges
- Resistant to oils, moisture, and cleaning chemicals
- Suitable for repeated food‑contact cycles
These characteristics make FDA silicone rubber ideal for seals, gaskets, tubing, and components used in food processing, beverage equipment, and sanitary production environments.
What Is Food Grade Rubber?
Food grade rubber is a broader category that includes various elastomers—such as EPDM, nitrile, natural rubber, and silicone—that meet basic food‑contact requirements. While food grade rubber can be safe for certain applications, it does not always offer the same level of purity, temperature resistance, or chemical stability as FDA silicone rubber.
Food grade rubber may be appropriate for:
- Low‑temperature food handling
- General‑purpose gaskets
- Non‑critical sealing applications
- Short‑term or disposable components
However, it may not deliver the long‑term performance required in high‑sanitation or high‑temperature environments.
How is FDA silicone rubber different from food grade rubber?
1. Regulatory Assurance
It’s formulated specifically to meet FDA 21 CFR 177.2600. Food grade rubber may meet general food‑contact guidelines but not the full FDA standard.
2. Temperature Resistance
It withstands extreme temperatures—from freezing conditions to high‑heat processing—without degrading. Many food grade rubbers have narrower temperature limits.
3. Chemical Stability
Silicone’s inert chemistry makes it resistant to oils, cleaning agents, and repeated sterilization. Other food grade rubbers may swell, crack, or degrade under similar conditions.
4. Purity and Extractables
It’s engineered to minimize extractables and leachables. Food grade rubber may contain additives that are acceptable for general use but not for high‑purity environments.
5. Longevity and Performance
Silicone maintains flexibility, resilience, and sealing force over time. Food grade rubber may harden, lose elasticity, or require more frequent replacement.
Where is FDA silicone rubber preferred?
Manufacturers choose FDA silicone rubber when they need:
- High‑purity seals and gaskets
- Components for food and beverage processing
- Tubing for sanitary transfer systems
- Materials compatible with sterilization
- Long‑term durability in demanding environments
Its combination of safety, stability, and regulatory compliance makes it a trusted material across food, beverage, pharmaceutical, and biotech applications.
What is FDA 21 CFR 177.2600?
FDA food grade silicone complies with 21 CFR 177.2600, which governs rubber articles intended for repeated food contact. This regulation specifies:
- Permitted ingredients
- Extraction limits for water and n-hexane simulants
- Testing protocols for repeated-use compliance
For engineers, this ensures that FDA food grade silicone is safe, reliable, and compliant with U.S. food contact regulations.
