Self-Adhesive Vibration Damping Sheet

Features

Megasorber D18 is a vibration damping material with self adhesive backing for ease of application. Using the latest polymer alloy technology, Megasorber D18 is polymer blend designed to provide high visco-elastic damping properties.

Key Benefits

• Reduce panel vibration and resonant noise effectively
• Ease to apply—just peel and stick
• Cost effective material to reduce low frequency structure-borne noise
• Safe and environmental friendly

Applications

High performance vibration damping material for metal panels to reduce impact or vibration induced structure-borne noise.

• Metal roof panels—reduce rain-drop impact noise as well as increase sound transmission loss
• Machinery and equipment enclosures—Megasorber D18 is adhered onto metal panels
• Marine—hulls, decks and bulkheads
• Machinery guards
• Stainless steel fabrications
• Hospital equipment
• Wall cladding
• Whitegoods
• Transportation—buses, locomotives and automotives
• Mining equipment

Tech Specs

Key Features

• High Damping efficiency: Damping Co-efficient (Cd ) well above 0.10
• Acrylic Pressure Sensitive Backing for easy application
• Excellent click-ability, i.e. very easy to cut to shape
• Thermal formable

Standard Product Range

Standard Product	System Loss Factor* (ASTM E756-83)
	20°C	70°C
Megasorber D18-1.7A	0.12	0.11
Megasorber D18-3A	0.19	0.20
Megasorber D18-5A	0.30	0.34

*Damping Co-efficient (also known as System Loss Factor) of 0.1 is equivalent to 20dB(A) noise reduction for a large freely suspended panel.
