Plexiglas or Rexolite ?

These two materials are the most commonly used for ultrasonic probe wedges.
Rexolite is a very interesting material with low attenuation and low sound velocity of 2350 m/s. It is thus well adapted for reduced-size wedges, allowing smaller angle, and for high frequency probes (7.5 MHz and more), thanks to low attenuation combined with shorter acoutic path.
Plexiglas is more resistant to abrasion.
