Avdec family of laminates
design of a specific Avdec laminate is dependent on
the response frequencies to be damped, the operating temperature
and environment, and the structure of the component.
offers Avdec laminate developed for three different
laminates can be designed and developed for additional temperature
ranges to meet the needs of specific applications. After product
evaluation, the proper Avdec film is specified for the
given noise and vibration damping application.
and L-40A for operating temperature ranging from 50°F
for operating temperatures ranging from 140°F to 225°F
for operating temperatures ranging from 175°F to 275°F
noise reduction is a very important issue in today's world.
Arvinyl offers Avdec damping material as a versatile
new solution to noise pollution. Avdec damping material
is composed of a layer of visco-elastic material sandwiched
between two layers of metal. It converts vibrational energy
by shear deformation of the visco-elastic layer, resulting
in a significant reduction in sound and vibration levels.
properties are usually stated as a loss factor . This loss
factor is the ratio of energy dissipated per cycle to the
total energy of the vibration. It is stated by a formula:
the formula, E is total energy of the vibration and the is
energy dissipated per cycle. The higher the loss factor, or
value of ,
the greater the vibration-damping effect.
