Accent sound absorber

Material represents elastic penopolietilen dark gray color with partial violation of zakrytoyacheisty structure, i.e. punched by needles.

• with a front covering and an assembly layer;
• with a front covering without assembly layer;
• without front covering and assembly layer;
• without front covering with an assembly layer.

Material with a front covering has the broken structure of the made foam polyethylene and a front covering. Sound absorption coefficient a materialatolshchina of 10 mm in the range of the frequencies of 2500-6300 Hz - 0,5-0,7. Material can be released one - and multilayered. For receiving an assembly layer use water acrylic dispersions (KS), the glues fusions (GF) or sealants (MS). As a front covering use multilayered film material Multiten of LM (LM), a film polyethylene (PE), a film polyvinylchloride punched (In) various color scale. Temperature range of operation of material: without assembly layer - from minus 70 to plus 80 gr. With, with an assembly layer - from minus 30 to plus 80 gr. With

• Durability of communication of a front covering from the main not less than 1,5 N/cm
• Communication durability between layers not less than 2,5 N/cm
• It is not flammable

Notes: The most effective sound absorber. Does not decay under the influence of moisture.
