FAQ

1. What is coated silicone valve made of?

Coated silicone valves are made of high-quality silicone, with an additional oil-resistant or PTFE coating applied to the surface. The coating enhances durability, reduces oil absorption, and improves flow control performance.

2. What's the difference between coated valves and regular silicone valves?
The main difference is the surface treatment. Coated silicone valves have an additional layer (e.g., oil-resistant or PTFE) that improves resistance to oily or viscous liquids, enhances durability, and maintains smoother liquid flow compared to uncoated silicone valves.

3. Are coated silicone valves food grade?
Yes, YEJIA coated silicone valves are made from food-grade or medical-grade silicone. They are safe for use in food, beverage, and cosmetic packaging applications.

4. Can YEJIA customize the size and slit design of coated silicone valves?
Yes, we offer full customization, including valve size, slit type, hardness, and coating options, to meet your specific product requirements and packaging compatibility.

5. How does YEJIA ensure the quality and consistency of coated silicone valves?
YEJIA implements strict quality control at every production stage, including material inspection, precision molding, coating application, and final performance testing to ensure consistent flow, anti-drip functionality, and durability.

6. What industries use coated silicone valves?
Coated silicone valves are widely used in food and beverage packaging, cosmetic products, personal care items, pharmaceutical containers, and other liquid dispensing applications requiring oil resistance.

7. What's the MOQ for custom coated silicone valves?
The minimum order quantity (MOQ) typically starts from 100,000 pieces, depending on design and application. YEJIA provides prototype testing samples before mass production to ensure proper performance and compatibility with your packaging system.

8. Can YEJIA provide valves in other materials?
Yes, YEJIA can produce valves in alternative materials, including TPE, NBR, uncoated silicone, or specialty silicone compounds, depending on the application requirements.
