Key Considerations
When evaluating choose silicone grade for your application, consider these critical factors:
- Application Requirements — What specific use case does your product serve? This determines material grade, hardness, and certification needs.
- Certification Requirements — Different markets and applications require different certifications (FDA, CE, ISO 10993). Verify requirements before sourcing.
- Cost vs Performance — Balance initial cost against lifespan, maintenance, and replacement frequency. Higher-quality choose silicone grade often provide better total cost of ownership.
- Supplier Capability — Verify factory certifications, quality systems, and production capacity match your requirements.

Frequently Asked Questions
What Shore hardness should I choose for kitchen products?
Food-contact silicone kitchenware typically uses 30-50 Shore A. Softer (30-40 Shore A) feels more comfortable for items like spatulas; medium (40-50 Shore A) provides better durability for molds and high-use items.
What is the difference between food-grade and medical-grade silicone?
Food-grade silicone meets FDA 21 CFR 177.2600 for food contact. Medical-grade meets ISO 10993 for skin/tissue contact and is a stricter subset. For kitchen products, food-grade is sufficient and more cost-effective.
How do I verify silicone supplier certifications?
Request current test reports from ISO 17025 accredited labs. Verify FDA compliance via 3rd-party testing, not just supplier claims. Ask for material specifications (D3, D4, vinyl content) and compression set data.
