Description
Neoprene Sponge Sheet – 120 kg Density (2 m × 1 m, Various Thicknesses)
If you need a reliable, compressible rubber seal that keeps water, air, and vibration out, these 120kg Neoprene sponge sheets are built for the job.
Designed for tight sealing applications, this closed-cell neoprene compresses under pressure to create a watertight and airtight barrier, making it ideal for doors, windows, enclosures, and panel sealing where standard rubber won’t perform.
Unlike open-cell foam, this material does not absorb water, meaning it won’t degrade, swell, or fail in outdoor or high-moisture environments.
🔧 Best For
- Door & window seals – prevent draughts, water ingress, and heat loss
- Electrical enclosures – create airtight seals around panels and cabinets
- Automotive sealing & anti-rattle – reduce vibration and eliminate gaps
- HVAC & duct sealing – compressible gasket material for air systems
- Outdoor equipment & housings – weatherproof joints exposed to rain and moisture
👉 If your application requires a compressible, weather-resistant seal, this is the correct material.
⚙️ Why This Material Works
- Closed Cell Structure – prevents water absorption and maintains seal integrity
- Excellent Compression Recovery – springs back after pressure for long-term sealing
- Weather & UV Resistant – suitable for indoor and outdoor use
- Oil & Chemical Resistant – performs in automotive and industrial environments
- Vibration Dampening – reduces noise and movement between surfaces

⚠️ Important Selection Tip
- Use thinner sheets (2–6mm) for tight compression seals (doors, enclosures)
- Use thicker sheets (8mm+) for gap filling, vibration isolation, or uneven surfaces
👉 Choosing the correct thickness is key to achieving a proper seal.
