Frequently Asked Questions (FAQ)

What is a metal detectable silicone rubber sheet?
A metal detectable silicone rubber sheet is a specialized silicone rubber material embedded with detectable metal particles. These particles allow the sheet to be identified by standard metal detection equipment commonly used in production lines, ensuring that if any fragment breaks off, it can be quickly detected and removed to prevent contamination.

How does the metal detection feature work?
The sheet contains uniformly dispersed metal detectable additives, such as ferrous or non-ferrous compounds. When passed through a metal detector, these additives create a detectable signal. The sensitivity is calibrated to identify fragments as small as 2.0 mm in diameter, meeting industry safety standards for contamination control.

Is the metal detectable silicone rubber sheet safe for food contact?
Yes, our metal detectable silicone rubber sheets are manufactured using FDA-compliant materials and processes. They are also certified under EU 10/2011 for food contact, ensuring they do not leach harmful substances and are safe for direct or indirect contact with food products.

What temperature range can these sheets withstand?
These sheets offer excellent thermal stability, operating effectively in temperatures from -60°C to 250°C. This makes them suitable for applications involving extreme cold, such as freezing processes, and high heat, including baking, sterilization, and industrial sealing.

Can the sheets be customized in terms of size and hardness?
Absolutely. We provide metal detectable silicone rubber sheets in a wide range of thicknesses (0.5 mm to 6.0 mm) and hardness levels (Shore A 40 to 80). Custom sizes, shapes, and colors can be produced based on specific customer requirements and application needs.

How durable are these sheets compared to regular silicone rubber?
They maintain similar durability to high-grade standard silicone rubber, with tensile strength ≥ 8 MPa, elongation at break ≥ 400%, and tear strength ≥ 25 kN/m. The addition of detectable particles does not compromise their mechanical properties, ensuring long service life even in demanding environments.

What industries commonly use metal detectable silicone rubber sheets?
Primary industries include food processing, pharmaceuticals, packaging, beverage production, and medical device manufacturing. Any sector requiring strict contamination control and traceability in their processes can benefit from these sheets.

Are there any certifications available for these products?
Yes, our metal detectable silicone rubber sheets are certified to comply with FDA (U.S. Food and Drug Administration), EU 10/2011 (European food contact material regulation), RoHS (Restriction of Hazardous Substances), and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) standards. Additional certifications can be provided upon request.

How should these sheets be stored and handled?
Store in a cool, dry place away from direct sunlight, ozone, and chemicals. Avoid sharp objects during handling to prevent cuts or tears. Clean with mild soap and water; avoid abrasive cleaners that could damage the surface or embedded detectable particles.

What is the lead time for custom orders?
Standard products are typically available from stock. For custom orders involving specific sizes, colors, or hardness, lead times generally range from 2 to 4 weeks, depending on the order volume and customization complexity. We recommend contacting our sales team for precise scheduling.
