Acoustic properties

Acoustic properties It is appropriate to mention acoustic properties here, as they are affected by density. Adding filler usually increases the density compared to the host polymer, and this is usually an unwanted side effect.However, it is common to make sound deadening composites by using high-density fillers such as barium sulfate (BaS04, 4.5 g/cm ) or magnetite (Fe304, 5.1 g/cm ) [23].

Moulded Polymers for Ultrasonic Applications

High Density Poly Ethylene (HDPE) pipe is becoming a popular substitute for steel pipe. Varieties of polyethylene used in industry can have an acoustic velocity range from about 2100m/s to about 2600m/s. Using PMMA or polystyrene as a refracting wedge material could result in very little refraction or even negative refraction.
