Ethylene Vinyl Acetate Eva For Sound Proofing

The first concern is that it s very stiff.

Ethylene vinyl acetate eva for sound proofing.

Eva is an elastomeric polymer that produces materials which are rubber like in softness and flexibility. The eva copolymer which is based on a high proportion of va greater than 60 is referred to as ethylene vinyl acetate rubber. Inhalation does not pose a threat unless you actually work in a processing plant. It is a suitable substitute for natural rubber vinyl neoprene polyurethane and pvc foams wood composites felts fiberglass and mineral wool.

Ethylene vinyl acetate eva polymer foam was prepared using a mold for this investigation. With that comes a higher resonant frequency we really want a limp barrier to keep its resonant frequency below the audible range since materials are acoustically transparent at their. Dekorman s eva ethylene vinyl acetate underlayment is designed for using under floated laminate bamboo and engineered wood floors and is ideal for many types of subflooring. The effect of the cell structure parameters and pore filling gas type on the sound absorption performance of the eva foam materials were analyzed in terms of their sound absorption capability.
