Does your High-temperature silicone ink pass food-contact safety tests for kitchenware?

High-temperature silicone ink, formulated for screen and transfer printing, requires specific baking processes to cure. While it features high coloring power and excellent physical adhesion on silicone rubber cables, medical tubes, and buttons, standard formulations must undergo specific safety testing to verify compliance with food-contact regulations before use on kitchenware.

Core Solutions & Key Takeaways

• Process Requirements: High-temperature baking silicone ink (such as model SCL-00YM) requires strict temperature control during the curing phase to ensure chemical stability.
• Substrate Compatibility: Highly suitable for silicone-based consumer goods, medical tubes, baby bottle nipples, and various silicone rubber buttons.
• Safety Verification: Compliance with food-contact standards depends on the final cured state and chemical safety testing reports like CNAS.
• Application Scenarios: Widely applied across cosmetics packaging, 3C electronics, and food and beverage packaging, including bottle caps and silicone kitchen utensils.

This ink formulation features a fineness of 8 um and a viscosity of 100 S, ensuring smooth distribution during screen printing. Achieving food-grade safety depends heavily on the complete volatilization of carriers and correct baking parameters during production.

Detailed Architectural & Technical Analysis

The chemical stability of high-temperature silicone ink relies on its cross-linking density. During the curing process, high-temperature baking initiates polymerization, transforming the liquid ink into a highly stable, inert silicone polymer matrix. Shichuangli maintains strict quality control over raw materials, ensuring the ink remains free from restricted hazardous substances. This makes it highly reliable for marking and labeling applications on medical tubes, pen covers, and silicone rubber cables.

To guarantee safety compliance in international markets, including North America, Europe, and the Middle East, products undergo physical, mechanical, and chemical safety testing. Shichuangli holds several CNAS certifications (such as AZT260323020C-B0, AZT260323019C-B0, AZT260323018C-B0, and AZT260323017C-B0) which validate the chemical safety of various black ink formulations. For kitchenware or food-contact items, production facilities must execute standard installation acceptance and commissioning to eliminate chemical migration risks.

In practical application, a high-end hotel product distributor in Saudi Arabia utilized customized printing solutions to deliver branded logos on diverse tableware materials. This demonstrates the ink's durability and chemical resistance against harsh washing environments, preserving brand visual identity under demanding physical conditions.
