Resolite (c) 2200 or 1422 for wedge

Hello!

Does anyone know, what type of rexolite normally used for ultrasonic wedges?

Specifications for 2200 informs that it is reinforced version of 1422 but has larger water absorbtion.

Andrey, Rexolite® 1422 is a thermoset cross linked styrene copolymer. I think it is the 1422 version that is most commonly used as a low-loss wedge material (the reinforced version would not be appropriate). It is available through several distributors

Thank you very much Ed!

2200 is not appropriate due to its acoustic properties or hardness?

Andrey, 2200 is a fiberglass reinforced version of 1422. It would not be a clear plastic and the acoustic properties are destroyed by the reinforcing mat which is inserted to improve impact toughness
