QUALITY TESTREPORTAspiration
to the perfection

After many years of distribution various sound damping material inthe markets we have realized that there are many problems with all of them.
We felt that there is a need for a drastic change in quality ofmaterial, it has become our dream – to create a perfect quality material.

Aspiration
to the perfection

PRODUCT PROBLEMS
Based on years of experience in distribution ofsound damping materials around the globe we haverealized that the materials developed for theRussian market do not meet the requirements ofapplication in countries with hot climates andidentified main problems with products :• Material melting• Material extrusion• Bitumen and other unpleasant smells• Material dropping from door or ceiling due toglue problems• Low or unstable efficiency of materials

Aspiration
to the perfection

PRODUCT WISHES
We have also heard and collected the wishes of ourclients and partners over these years, the most common
list is:• Easy and fast installation• Modern design• Convenient transportation and storage• Super light materials to lower down weight ofinstallation and reduce effects on fuel consumption
and acceleration

Aspiration
to the perfection

CREATING TESTS
We had to create a set of simple express testing
standards and equipment to ensure we can easy test
various products and optimize our products for thedemands of the market.
With these tests we are able to:• Show the real quality of materials• Proceed our own Permanent and independent
production QC, to be sure in stable quality.
• To speed-up development of new materials

Aspiration
to the perfection

Passion of Quality
We have spend two years on R&D of our newperfected quality products based on the test results
and have made amazing progress.
We are happy to assure you that our new products
are free of the following problems:• Melting• Unpleasent Smell• Extrusion• Falling off• inStability and low efficiency
Our assurance comes after multiple tests not only of
our own products but also other products in themarket.

Adhesion of products to the surfaces,
ensuring they do not drop off easily over timeand increase efficiency of damping

TEST 3 ADHESION

Determination of materials with thegreatest adhesion.
The test is intended to determine the materials with thehigher adhesion by comparing the amount of time thematerial takes to fully drop off the surface. The time is thencompared among various products. Adhesion is tested on
painted automotive steel surface.

TEST 5 Mechanical Loss Factor (MLF)

Mechanical Loss Factor
Test to find out how much vibration
does the material effectively absorb

TEST 5 MLF

Assessment of the efficiency of vibration
damping materials.

The Mechanical Loss Factor (MLF) - is one of themost important indicators of vibration dampingmaterials.
The higher the value, the more vibrations will beabsorbed.
The vibration damping process is the process ofabsorbing vibration energy from metal and converting
into internal heat .

TEST 5 MLF:
Description

Modal analysis
software

1. Apply samples of material on metal plate
2. Calibrated impact by metal ball on metal plate
to create acoustic impulse.
3. Record acoustic impulse with spectrum
analyser and measure energy, duration andspectrum of this impulse to evaluate and compare
damping efficiency of different samples.
