Sound deadening materials for housing and capsule surfaces

Protecto pf 810 and Protecto pf 820 are bitumen-impregnated insulation materials made of recycled paper. These materials help stabilise all kinds of metals and plastics while reinforcing them and adding weight.

This has a sound deadening effect, meaning that they prevent the spread of structure-borne sound. They also dampen sound passing through walls from different rooms, successfully preventing the spread of airborne sound. Bitumen-elastomer compounds like Protecto pf 830 offer a heavy weight and excellent flexibility – even at low temperatures.
