Cushioning foam

Description
50 mm heavy-weight (5 kg/m²) corrugated PU ether absorption foam bonded to 3 mm spring foam. Temperature range: -25°C to +110°C. Fire resistance classification: M4. ► STRASONIC® is a range of complex materials designed to provide the best acoustic isolation. ► Their structure is based on polyurethane foams or cellular rubber. ► Their main function is to reduce airborne noise (isolation, absorption and damping) in partial or complete enclosures of machinery.

Advantages

• The heavy-mass corrugated PU absorption foam is suitable for many applications: Air Generating Stations
• Presses
• Electric motors
• Gearboxes
• Compressors

Acoustic performance
The heavy-mass corrugated PU foam provides excellent acoustic absorption across typical coating assemblies. Approximate increase in sound insulation on steel sheet: +25 dB. Effective acoustic range: approximately 500 Hz to 5,000 Hz.

Other information
Wide operating temperature range for this soundproofing foam. Available in adhesive and non-adhesive versions.
