  Vibration Damping Materials...   
AluDamp

AluDamp is manufactured from 0.5mm aluminium with an energy absorbing visco-elastic polymer on one side.

It is designed to minimise noise and vibration radiating from resonating structures and can reduce noise by up to 30dB.

AluDamp is available in flat sheets and can be die-cut to size and shape. The material is supplied with a release paper enabling it to be bonded directly on to a substrate.

Fire/Smoke performance:
Tested to BS6853 UK Railway Standards


Damping Compound

Vibration Damping compound is a water based co-polymer emulsion with mineral fillers and a low permeable, elastomeric binder.

It is solvent free, easy to apply and can be used in most interior and semi-exposed areas.

It is designed to reduce noise by damping resonant vibration caused by continuous or impulsive excitation of the substrate to which it is applied.

Vibration damping Compound can be sprayed onto smooth and irregular surfaces. Once applied it has a monolithic spray texture finish. It may be possible to match specific colour requirements - please enquire for details.

Fire/Smoke performance:
Tested to BS6853 UK Railway Standards
M1 and F1 Classification in accordance with French Regulations
AST E 162 and ASTM E 66


Damping Sheets -Bitumen

Bitumen Based Damping Sheets are manufactured from bitumen fillers with added mineral fillers and synthetic rubber to form a highly visco-elastic material.

They are designed to minimise acoustic and vibration radiation of sheet metal. They can improve sound insulation performance of the substrate by adding mass.

There are two grades of Bitumen Based Damping Sheets supplied to the rail industry (DS3A and DS5A). Both have an aluminium foil facing heat sealed to one side for improved fire performance. They are available with a self-adhesive backing, in sheets or die-cut to size and shape.

Fire/Smoke performance:
M1 and FO Classification in accordance with French Regulations


CoustiPlate

CoustiPlate is manufactured from two layers of corrosion resistant, zinc coated mild steel, stainless steel or aluminium with an energy absorbing visco-elastic core.

The resulting constrained layer damping sheet is designed to reduce sound transmission loss by eliminating resonance.

CoustiPlate is available in flat sheets and can be die-cut to size and shape. The material can be sheared, punched, drilled, screwed or riveted in the same way as conventional sheet metals.
