They are thermoplastics which have vibration and sound insulation capability owing to their high density values. If required, they are given three dimensional forms through the thermoform production technique. Heavy coating products are perfect sound absorbers used in insulating sounds originating from vibration and for blocking the passage of sound in acoustic insulation. They are produced as EPDM-EVA-BITUMEN and PVC based products. They have usage in different sectors and mainly in automotive and white appliances sectors. They are used both separately and by being laminated with PU, PE and melamine foams to increase their efficiency.
