Dash insulator and carpets are used to reduce engine and road noise into the car interior cabin.
A typical dash insulator or carpet system consists of a steel panel (vehicle body panel), a porous decoupler and a heavy layer in the form of sandwich construction. To make these parts, Cannon has developed two different production systems:
RRIM and BackFoaming
Heavy Layer PUR is a two components PU resin which is heavily filled with Barite especially in Polyol component, and applied onto a surface through a spray or a closed-mould injection (RRIM) process.
