Transulate has good sound-absorbing and sound-insulating effects. Its sound-absorbing principle is to propagate sound and sound waves into the sound-absorbing cotton for acoustic conversion and finally disappear. Since there are countless interconnected micropores in the sound-absorbing cotton, it can buffer and absorb sound waves, thereby achieving an effective sound-absorbing effect. Sound-absorbing cotton is made from different ingredients, and sound-absorbing cotton made of different materials will have different sound-absorbing effects.

Traditional sound-absorbing materials have many shortcomings, such as low sound absorption coefficient, easy to produce secondary pollution, short service life, etc. They will gradually withdraw from the market and be replaced by new sound-absorbing materials. Compared with traditional automotive sound-absorbing materials such as open-cell foam, felt, PET cotton and other materials, transulate has the characteristics of strong sound absorption, light weight, low thermal conductivity, flame retardant, and low VOC volatilization. It is a commonly used automotive acoustic material.

Transulate is made of PP (polypropylene) and PET (polyester) fibers in different proportions (varies due to different applications, gram weight ranging from 10 grams to 800 grams) through high temperature and high pressure melt-blown. It has a three-dimensional network continuous porous with a 2 μm diameter of polypropylene and a 25 μm diameter of polyester. (Skeleton support structure). Through this processing method, it is possible to make lightweight and bulky materials from finer fibers. In this way, when the acoustic vibration passes through the fiber pores in the melt-blown two-component material, its energy is converted into heat energy under the action of friction loss and is effectively suppressed.

At present, transulate is mainly used in the automotive field, and a small part is used in the construction field. Transulate has both the fluffiness of PP meltblown material and the hardness of polyester fibre, absorbing the advantages of the two raw materials, with excellent sound-absorbing properties, non-toxic, mildew and moisture resistant, good thermal insulation, easy to assemble and other characteristics, gradually applied to automotive interior sound-absorbing/sound insulation parts, recognised by the majority of users and vehicle manufacturers.

Taking the Tesla Model 3 as an example, the door interior panel is covered with a large area of transulate, which can reduce the vibration caused by loosening and damage of various components in the door trim panel and the noise caused by collisions.

In addition, transulate's lightweight characteristics are very friendly to electric vehicles. With the popularity of electric vehicles, lightweighting has become an important trend. Due to the presence of electric vehicle batteries, the weight of the vehicle body increases, so it is necessary to find a lightweight material to compensate. Since transulate is made of lightweight materials, it can effectively reduce the load in the car and improve the cruising range and performance of electric vehicles. With the same sound insulation effect, the weight of transulate is only 1/3-1/2 of traditional felt, which significantly reduces the weight of the car body and improves the endurance of electric vehicles.

Compared to felt materials, transulate has no odor and will not become moldy. Felt can easily breed mold in a humid environment and release unpleasant odors, affecting the air quality in the car and the health of the driver. Due to the material characteristics of transulate, it is not easy to store moisture, effectively avoiding the growth of mold and keeping the air in the car fresh and comfortable.
