CTK DOMINATOR – FOR PROFESSIONAL CAR AUDIO SYSTEMS SQ / SPL

CTK Dominator – a "hardcore" series of mats for the most demanding professionals who accept no compromise. The technologically advanced polymer-butyl layer was developed from high-molecular-weight polyisobutylene, several types of rubber, and special additives and fillers. This combination enhances the polymer's molecular structure, leading to increased performance. The composite has a very high viscosity to the substrate and is characterized by a very high vibration absorption coefficient (MLF higher than the Premium series). To further enhance performance, CTK Dominator mats use 150-micron aluminum foil! This is 50% thicker than the Premium series and other similar products from renowned brands. Despite this, the material is still sufficiently flexible during installation and relatively lightweight due to the high percentage of special high-quality rubber and refining additives.

Intended use:
This product is designed for use in the most advanced soundproofing systems, for the effective reduction of body vibrations and road noise, and in extreme SPL (Sound Pressure Level) car audio projects, which require the highest-performance anti-vibration materials with increased stiffness. Dominator mats are ideal for reducing strong vibrations in body parts and for additional stiffening of large body surfaces (roof, floor, side panels, doors, etc.). CTK Dominator mats are also ideal for professionally preparing bodywork and door chambers for the installation of high-end SQ (Sound Quality) car audio equipment. These mats guarantee the highest stiffness and stability of the door chamber surfaces, including the surface above sealed process holes. After using CTK Dominator, in many cases, additional surface reinforcement in process holes will no longer be necessary. CTK Dominator mats are available in three thicknesses: 2.0 / 3.0 / 4.0 mm. More detailed application guidelines for each thickness are specified in the parameter descriptions (below).

PLEASE NOTE: These mats aren't super soft, super flexible, or cheap. They're simply the most effective of all similar products of similar thickness on the market. They feature specially thickened and stiffened aluminum foil to achieve the highest possible stability for the dampened surface (because that's the main focus for this type of work). Don't compromise on this product.

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.

INSTALLATION:
Self-adhesive CTK Dominator mats can be applied to flat or embossed surfaces. They can be installed in a wide temperature range without the need for preheating, but the most comfortable operation is achieved at ambient temperatures between +10ºC and +30ºC. The surface to be bonded must be dry, clean, and very well degreased. To maximize the damping properties, press the mat firmly after application, e.g., using a roller or other tools, to ensure complete adhesion to the entire surface of the damping substrate without creating air pockets. The self-adhesive butyl polymer layer has self-vulcanizing properties, which, over time, further increases the material's adhesion to the substrate, creating a cohesive, inseparable 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 A 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-quality 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.
