[Examples of use]
-Shock buffering and protection when dropping belt equipment (notebook PC, mobile phone, digital camera, movie, PDA, etc.)
・ Vibration prevention (to reduce noise) (motors for digital cameras and movies, solenoid valves, etc.)
・ Sound suppression measures (Material sound: various motors, etc. Airborne sound: microphone holder for portable equipment, etc.)
-Sound insulation measures (movement of resonance point-specification of high specific gravity material) - electromagnetic wave (x-ray, UV light) shield
[Characteristics]
・ Excellent vibration absorption performance. (Tan δ is the highest level in the industry and has low temperature dependence)
・ Excellent in both shock absorbing and damping properties.
・ Various variations (standard, high impact buffer, flame retardant, heat, oil, and wear resistant specifications) are available.
・ Can be formed into any shape, including sheets.
・ Foaming with excellent sound absorption properties is also possible.
・ G grade with high specific gravity specifications is available to add sound insulation characteristics (movement of resonance point).
-Compatible with various environmental standards (siloxane free, RoHS, degassing, and REACH).
-Post-processing such as adding various films or double-sided tape is possible.
Radiation shielding materials
Miyatrom-R series
[Examples of use]
・ Shielding of radiation (γ-rays and x-rays) (Lead substitute: medical and industrial equipment and protective clothing for exposure prevention)
・ Protection of electronic parts (ASIC, TFT, and memory) from radiation and ultraviolet rays
・ Prevention of radiation diffusion and diffuse reflection
