CTK PREMIUM – THE BEST FOR THE BEST!

CTK Premium is one of the most advanced self-adhesive anti-vibration materials on the market, made from a state-of-the-art composite of high-quality butyl rubber, specialized polymers, and a reinforcing embossed blackened aluminum foil, 100 micrometers (0.1 mm) thick, further improving acoustic properties. This material is characterized by very high vibration damping (absorption) effectiveness across a wide temperature range, high installation flexibility, and very high viscosity and adhesion to the substrate. At the same time, within a comparable thickness and vibration damping effectiveness (MLF coefficient), CTK Premium damping mats are among the lightest anti-vibration materials of their kind produced in Europe. This means that by using the thinner, and therefore lighter, CTK Premium series mats, vibration and noise reduction can be achieved at a level that would be achievable using other, less technologically advanced materials with much greater thickness and weight. The CTK Premium series also offers products with the widest range of available thicknesses on the market (1.8/2.2/3.0/4.0mm). This is a crucial element when planning and implementing professional vehicle soundproofing installations. By selecting the appropriate mat thickness for a specific vehicle location, you can most effectively utilize the properties of the soundproofing material without unnecessarily increasing the overall weight of the installation. This avoids unnecessary weighting of less acoustically important vehicle components with thicker mats, while simultaneously applying the most effective, thicker products in the most critical and important areas of the car body in terms of noise reduction. CTK Premium series vibroacoustic materials are uncompromising products designed primarily for professional car audio installers and renowned vehicle soundproofing companies, targeting the most demanding customers who are willing to pay a little more for the highest efficiency, quality, and comfort.

CTK vibration dampening materials are non-toxic and safe to use, in accordance with European Union (EC) requirements. These products have a positive laboratory test report, accepted in EU countries, confirming compliance with the requirements of Regulation (EC) No. 1907/2006 of the European Parliament and of the Council of 18 December 2006 – REACH (Registration, Evaluation, Authorization and Restriction of Chemicals).

NOTE! Some suppliers of other brands of soundproofing mats sometimes declare their products' non-toxicity or safety based solely on a RoHS certificate. Such certification does not apply to soundproofing materials, as the RoHS directive applies only to electrical and electronic products, not chemicals. Such soundproofing materials may not meet legal requirements or guarantee safe use.

APPLICATION AND INSTALLATION

CTK Premium mats are among the most effective and lightest anti-vibration materials available on the market. They are designed to effectively reduce vibration, noise, and acoustic resonance in car body and upholstery components. They are particularly effective when improving cabin acoustics, installing and using high-end car audio equipment, and during professional general vehicle soundproofing installations. CTK Premium mats are self-adhesive, flexible, and easy to apply to flat or complex surfaces. They can be installed in a wide temperature range without the need for preheating, but the most comfortable work is achieved at ambient temperatures between +10ºC and +30ºC. The surface to be covered must be dry, clean, and very well degreased. To maximize its dampening properties, the mat should be firmly pressed after application, e.g., using a roller, to ensure complete adhesion to the entire surface of the substrate being damped, without creating air pockets. The self-adhesive butyl polymer layer has self-vulcanizing properties, thanks to which the adhesion of the material to the substrate increases even more over time, creating an inseparable, coherent whole.

DAMPING EFFECTIVENESS

When soundproofing a car, the desired effect is achieved by acoustically insulating its interior and, above all, by significantly reducing (damping) the amplitude of mechanical vibrations in the metal and plastic components of the car's body and cabin. To achieve this, flexible and slightly elastic materials (e.g., butyl rubber-based) are applied to the damped components. These materials suffer from significant mechanical energy losses due to internal friction. As a result, vibration energy is absorbed by the damping material and converted into heat. The ability of a given material to absorb mechanical vibration energy depends on many factors, including its design, chemical composition, weight, thickness, etc. This determines the mechanical loss factor ( MLF ), which is one of the most important parameters to consider when selecting vibration-reducing materials. This coefficient is expressed numerically in the range of 0.00–1.00 for a specific frequency and temperature (the higher the MLF value, the greater the material's ability to dampen vibrations). To noticeably reduce noise and vibration inside a vehicle, materials with the highest possible mechanical loss factor should be selected. When damping car body components, the lowest possible weight of the damping material is also important, which often does not translate into maximum damping effectiveness. Therefore, the best compromise should be sought between a high mechanical loss factor (MLF) value, low material weight, and an adequate price. In the car audio industry, when damping car doors where speakers will be installed, it is common practice to "close" the factory-made holes by sealing them with damping mats (creating a sealed speaker chamber). In these places, the best solution is to use mats with a high MLF factor, moderate weight and a thicker aluminum foil (100 micrometers or more) , which provides greater stiffness and stability of the surface over the sealed technological holes.

HOW TO EFFECTIVELY SILENCE YOUR CAR?

The highest level of soundproofing a vehicle's interior can only be achieved by comprehensive soundproofing (damping, acoustic isolation, and soundproofing) of all key body and interior components, layering these components (where possible and space permits) with three different types of the most effective, top-class materials, each with different acoustic properties, operating in a different frequency range, and fulfilling a different role. These are:

• layer 1 – highly effective anti-vibration materials that dampen vibrations and resonances of body elements and additionally isolate the interior from external noise, which are high-quality mats based on butyl, aluminum and polymers with the highest possible MLF value (e.g. CTK Dominator, CTK Premium, CTK Standard Professional damping mats),
• layer 2 – foam insulation – sound barriers with a closed-cell structure, blocking the passage of road noise into the cabin and additionally thermally insulating the interior against excessive heating and rapid cooling (e.g. CTK Elastic, CTK Elastic F rubber foams, CTK TempoFix polyethylene foams),
• Layer 2/3 – soft, porous sound-absorbing materials with an open and/or partially closed cell structure, which, in addition to their sound-absorbing properties, also act as shock-absorbing spacers and dampen the resonance of plastic upholstery elements, reducing the creaking and squeaking of these elements (e.g. CTK SilenceFix and CTK WaveFix polyurethane sound-absorbing foams, CTK CaiMat non-woven fabric-based sound-absorbing mats). For the best road noise reduction effect, it is also recommended to install the CTK Block Pro acoustic membrane as the last third layer on the lower horizontal body elements.
