What's the core difference between Silicone and Rubber (e.g., EPDM, NBR)?

Avoid direct UV/ozone exposure, sharp objects, or heavy stacking.Do not store with PVC or plasticizers to prevent migrative contamination.

Keep in sealed bags in a cool, dry place (ideal: 10°C–25°C). For Further Assistance:

Please provide:

• Operating temperature range
• Media exposure
• Expected service life
• Certification requirements
• Annual volume estimate

Silicone is thermoset and not biodegradable. However, it can be:

Physically recycled as filler for low-demand products.

Chemically decomposed to recover silica.

Replaced by bio-based silicone alternatives (partially from renewable resources).

MOQ: Usually 500–5,000 pieces, depending on mold complexity.

Lead Time: 15–25 days for tooling; 3–4 weeks for production after sample approval.

Tooling: Precision CNC-machined molds with optimized parting line design.

Process Control: Adjusted curing temperature/pressure to minimize shrinkage variance.

Post-Processing: Parts conditioned at constant temp/humidity for 24h before measurement.

Thermal Aging: Continuous high heat causes oxidative crosslinking.

Ozone/UV Exposure: Add UV stabilizers or use weather-resistant grades for outdoor use.

Chemical Attack: Swelling in non-polar solvents may lead to subsequent embrittlement.

Material Certificates: Request FDA 21 CFR 177.2600, LFGB, EU 10/2011 compliance docs.

Manufacturing Environment: Parts should be produced in a controlled clean area.

Test Reports: Ask for batch-specific data on extractables, heavy metals, and cytotoxicity (if applicable).
