Metal Detectable Silicone

Metal detectable silicone is formulated with special additives that makes it detectable by X-ray machines, magnetic separators, or metal detectors. If a piece of a silicone seal or gasket breaks off during production, it can be identified and removed. Applications include food and beverage processing, dairy, and pharmaceuticals. Choose solid silicone sheet or uncured silicone compound.

Metal detectable seals are used to increase safety and reduce downtime by quickly sequestering seal fragments in-process by magnetically collecting the fragments. This material is easily die-cut and provides a superior gasket and sealing solution. Thicknesses range from .010” to .500”,  widths are available to 60”, and this material is available in various opaque colors.

Material Properties

What are Metal Detectable Silicones?

Metal detectable silicones are specially formulated silicone rubber compounds that contain finely dispersed metallic or metal-detectable additives, making them detectable by metal detection and X-ray equipment commonly used in food, beverage, and pharmaceutical processing environments.

Advantages

  • Detectable by Metal Detectors: If a piece of the silicone breaks off into the product stream, it can be quickly identified by standard detection systems, preventing contaminated batches.

  • FDA and/or USP Compliance: Many grades are compliant with FDA 21 CFR 177.2600 or USP Class VI, making them safe for use in direct food or pharmaceutical contact.

  • Color-Coded: Typically blue for high visibility, as blue is a rare color in food products and easily spotted by workers and optical sensors.

  • Retains Silicone Benefits:

    • Flexible across wide temperature ranges (often -60°F to +450°F)

    • Chemically inert

    • Non-toxic and odorless

    • Resistant to water, steam, cleaning agents, and aging

Applications

  • Food processing equipment gaskets, seals, and O-rings

  • Pharmaceutical manufacturing tubing and seals

  • Dairy and beverage bottling lines

  • Bakery ovens and conveyor systems

  • Meat and poultry processing plants

  • Preventative maintenance programs to meet HACCP and GMP standards

Additional Considerations

In regulated industries, foreign object contamination is a major safety concern. Metal detectable silicones help:

  • Minimize product recalls

  • Protect consumer health

  • Ensure regulatory compliance

  • Reduce downtime and cleaning costs
