AptFlex F48P, from Acoustic Polymers Ltd, is a high performance acoustic absorbing tile designed to meet the requirements of applications in the frequency range 200 kHz to 1.5 MHz. It is a micro-bubble filled, pre-cast polyurethane sheet. It is designed to exhibit very high levels of echo reduction and good insertion loss.
AptFlex F48P has a complex wedge structure on its outer surface to reduce specular reflections and provide geometrical acoustic impedance matching.
