Sound Barrier Acrylic Sheet


description

 

Acoustic Sound Barrier Acrylic Sheet,compared with our GP acrylic sheet,it embedded polyamide threads which have stronger impact resistance,not only can avoid debris falling backward secondary injury in the impact event of circumstances,but also stop the little birds in knocking down to the entirely transparent sound barrier and save their lives.It is widely used in the high way noise barriers because it is great features.Sound proof panels for Highway Noise Barrier is the best application for this product.

feature

  • High transmittance of 93%
  • Perfect weather resistance(long-term outdoor use up to 25 years,light transmission can still reach 89%)
  • Hard and tough, not easily deformed
  • High intensity shatterproof integration capabilities(Acrylic reinforced sheet with embedded polyamide threads have very strong impact resistance, can avoid debris falling backward secondary injury in the impact event of circumstances. All have bird protection function)
  • Easy processing (cutting, drilling)
  • Recyclable (environmentally friendly new materials)

Modified Acrylic comparison with other materials

  • Good sound insulation

Noise reduction mechanism of acoustic panel is reflected rather than absorbed. After testing,15 and 20 mm acrylic sheet,respectively 32 and 35 db noise reduction.If the top of the acoustic panel made inwardly curved shape, sound effects will be better.

  • Excellent weather resistance 

Acoustic panels in a variety of applications shows excellent weather resistance for outdoor use warranty of 25 years;while others such as PC sheets, turn yellow in several years only,on the visual environment have been affected.

  • High transparency

High transmittance over 93% (transparent plate), even higher than glass.The initial transmittance is better than other transparent plastics,and with surface damage,the transmittance will be further reduced for other transparent plastics such as PC sheet;

  • Processing is simple

Compared with glass,Acrylic sheet is more safer and easier to cutt and transport on site.In addition,acrylic acoustic panel can be cold bend (minimum bend radius is 300 times of the thickness of the plate 300 times) also be thermoformed,modeling and diverse;

  • Strongimpact resistance

Acrylic acoustic panel has excellent impact resistance;while the glass is very easy to be broken and will be completely destroyed by the impact;

  • Light weight

Lighter than glass(specific gravity of about 50% of the glass),common support structure can be used,also more secure,convenient for installation.

  • Protection of Birds

Acrylic reinforced sheet with embedded polyamide threads making it easier for birds identify in order to avoid bruises on the highway.
