View Details On Bitumastic Sheet
Bitumastic sheet is a very dense / heavy material which has almost zero elasticity. It is widely used in industry to dampen the vibrations of thin metal sheeting and is often used under car bonnets or applied to large metal containers. Rolled into sheet format and with a self adhesive backing bitumastic sheet is also ideal for the damping of unwanted vibrations / resonances in wooden loudspeaker panels. Adding to our selection of highly popular Bitumastic Sheet in thicknesses of (5, 2.5)mm we now have available a further material thickness of 1.5mm. This is available as self-adhesive, cut sheet, sized at (200 * 300)mm.
