3M 1100 Disposable Foam Earplugs

The 3M 1100 Earplugs are disposable foam ear-plugs designed for hearing protection in noisy work environments. They’re made from soft polyurethane foam that conforms to the shape of the ear canal for comfort and effective noise attenuation. The tapered design makes insertion easier, while the slow-recovery foam allows the plug to expand once inserted. They are suitable for industrial use, construction, manufacturing, woodworking and other settings where noise exposure is high.

Key Features

• Soft polyurethane foam, hypoallergenic — provides a comfortable fit and minimizes irritation.
• Tapered cylindrical design that helps fit a wide range of ear-canal sizes and ensure a good seal.
• Smooth, dirt-resistant surface for better hygiene and easier cleaning when disposable use.
• Slow-recovery foam—rolled down for insertion, then expands to fill the ear canal for better noise blocking.
• Noise reduction capability: depending on region and standard, attenuation (for example SNR up to ~35 dB) for high noise exposure use.
• Available in both un-corded (model 1100) and corded (model 1110) versions—to suit user preference for earplug type.
• Compatible with 3M’s E-A-Rfit™ and other hearing-protection validation systems, supporting fit-testing and worker protection programs.
• One-size-fits-most design, making wearable compliance simpler.

Typical Applications

• Automotive manufacturing
• Chemical & pharmaceutical manufacturing
• Construction, heavy engineering and metal processing
• Woodworking and textile manufacture
Also useful in any environment with prolonged noise exposure where hearing protection is required.
