Grade Comparison: Industrial vs Food vs Medical
All three grades are real silicone rubber — the same base material family. What changes is the testing, the production control, and the paperwork behind them:
Factor | Industrial Grade | Food Grade | Medical Grade |
|---|---|---|---|
Key Compliance | General industrial standards | FDA 21 CFR 177.2600 / LFGB | USP Class VI + ISO 10993 |
Testing Focus | Size, hardness, physical performance | Migration & extraction tests (no harmful substances move into food) | Full biocompatibility tests (cytotoxicity, sensitization, irritation) |
Production Environment | Standard workshop | Clean, contamination-controlled workshop | ISO 13485 quality system, cleanroom production |
Documentation | Batch record, basic CoA | Declaration of Compliance + CoA | Full lot traceability, CoA, test reports on request |
Cure System | Peroxide (standard) | Peroxide or platinum | Platinum |
Relative Price | \$ (lowest) | \$\$ | \$\$\$ (highest) |
How to choose:
If the gasket never touches food or the human body, industrial grade is the smart buy — you get the same sealing performance without paying for tests you do not need. If it touches food, you need food grade. If it touches the body, medicine, or body fluids, only medical grade is acceptable.
Common Applications
Industrial grade silicone gaskets are the everyday workhorse of sealing. Typical uses include:
Machinery covers and access panels
dust, splash, and vibration sealing on machine housings
Electronics housings and electrical enclosures
junction boxes, control panels, LED lighting, outdoor communication cabinets
HVAC equipment
duct flanges, air handling units, filter covers, dampers, and access doors
Automotive non-fuel systems
lighting assemblies, HVAC units, battery enclosures, and cabin equipment (for fuel and oil contact, use fluorosilicone instead)
Industrial valves and pumps
general service with air, water, and mild chemicals
General equipment assembly
anywhere a flexible, heat-stable, weather-proof seal is needed at a fair cost
Not sure if your application can use industrial grade? Tell us what the gasket touches — air, water, food, oil, or something else — and we will confirm the right grade for free.
What Is Industrial Grade Silicone?
Industrial grade silicone is the general-purpose member of the silicone rubber family. It is made for everyday engineering and manufacturing jobs — sealing, insulating, cushioning, and protecting — where the part does not touch food or the human body. It shares the same silicon-oxygen polymer backbone that gives all silicones their famous stability, but its formula is optimized for mechanical performance and cost efficiency rather than for regulatory certification. In simple terms: it is the practical, no-nonsense silicone that industry runs on.
