More detail
Physical Specification
- Based on a polyurethane rubber material,single-ply nominally homogeneous layer
- Pyramidal structured surface with maximum thickness of tiles: 8 mm.
- Tile dimensions: 200 x 250 x 10 mm
- Coefficient of linear thermal expansion: 200 ppm/oC.
- Specific gravity is 1.01 g/cm3 is close to that of water
- Longitudinal wave speed (1 to 10 MHz) is ≈1500 m/s
- Acoustic impedance is 1.5 MRayls
- There is a resistance to Isopropyl Alcohol (IPA) and trichloroethylene
- It can be affected by ketones (MEK, Acetone) which causes it to swell and dichloromethane which also cause swelling and break down
- Avoid prolonged exposure to Ozone and UV
- The stability of F28P is very stable due to cross-linked nature of polymer
- The material can be cut with a sharp craft knife to make various geometries to meet exact end-user requirements
Acoustical Specification
- High transmission loss, approximated by 20 dB/cm/MHz.
- High echo-reduction, greater than 20 dB at 1 MHz, to greater than 40 dB above 6 MHz.
