| Abstract: |
The rectangular and square samples of bio-plastic materials
namely, polymethyl methacrylate (PMMA), polycarbonate (PC), polystyrene plastic
(PS material), polypropylene (PP), polyvinyl chloride (PVC), bakelite (G-10),
nylon, Y-dent and teflon (PTFE) used for different applications in hospitals
have been studied.
These samples collected from different hospitals in Delhi
(Safdarjang Hospital,
Batra Hospital, AIIMS) have been studied for
ultrasonic velocity, elasticity, acoustic impedance etc. at room temperature
(24ÂșC). The average values of ultrasonic velocity and elasticity are found to
vary directly with the density. The ultrasonic parameters measured at 2.5 MHz
are reported here.
