Asbestos tape

Product description

Asbestos tape

Asbestos refractory tape is one of the oldest insulation products that was widely used in various fields until the end of the twentieth century. Today, these tapes are often used to seal motor homes for the reasons that will be discussed below, and for this reason, they are also known as engine room fireproof tapes.

Pars Sanat Refractory Store is ready to provide advice, sell and send asbestos refractory tape with various dimensions and thicknesses, all over the country.

Refractory tapes, which are narrower than refractory fabric and in most cases do not exceed 20 cm in width, are often used for sealing pipes, sealing and insulating boilers and furnaces. The variety of these tapes is very large and buyers can choose the fireproof tape or conveyor of their choice based on environmental conditions and required functions. In this article, we intend to study asbestos refractory tape, as one of the oldest refractory tapes on the market, and examine its strengths and weaknesses.

Asbestos fibers have a high heat tolerance of up to 550 ° C. If we put asbestos fibers under a microscope, we can clearly see the sword shape of these intertwined fibers. This degree of entanglement results in the cohesiveness and strength of asbestos fibers as well as a dramatic reduction in energy loss in equipment insulated with this product. However, due to the toxic dust on these fibers, the use of asbestos is only allowed in places out of reach of humans, including motorhomes.

The ability to compress asbestos fibers and produce soft washers as thermal insulation was discovered by an Austrian in the late 19th century. This refractory product quickly found a special place among the industries and became one of the first choices in the field of insulation. But about a hundred years later, in the late twentieth century, scientists and specialists began extensive studies in the field, receiving numerous reports of people being exposed to asbestos from a variety of dangerous lung diseases, such as lung cancer. The results of these studies showed that asbestos has very bad effects on the environment as well as human health. The findings of these experiments were so shocking that they called asbestos a dangerous dust and banned its use in most places. Of course, as can be guessed, a complete ban on asbestos is almost impossible, given its high heat resistance and remarkable impermeability. For this reason, the use of fibers in this refractory material was limited to places that did not have close contact with humans and nature; Including boiler, furnace and engine room. Today, another solution that experts have tested to reduce the damaging effects is to impregnate asbestos or cotton wool with another refractory material to prevent the release of toxic dust.

Thus, at present, asbestos tape is produced in the form of three products and the strength of each of these tapes can be increased by reinforcing it with stainless steel wire or anconel. Of course, it should not be forgotten that none of these products are allowed to be used in public places or in contact with humans and nature:

Dust-free asbestos tape; This strip is made of pure asbestos fibers and has a heat tolerance of up to 550 degrees Celsius. Due to the lack of protection on this strip and the possibility of spreading toxic dust of this product, its use is only allowed in motorhomes, boilers, pipes, etc. to be out of human reach.
Dusty asbestos tape; The surface of this type of asbestos tape is covered with a layer of Teflon and for this reason, this product is also known as Teflon valve. Dusty asbestos tape is used to insulate parts in power plants, buildings and factories. Of course, the thermal resistance of this refractory tape, due to the presence of Teflon, is 350 degrees Celsius.
Foil asbestos tape; In this type of refractory tape, the surface of the asbestos tape is covered with a layer of aluminum foil. In this product, in addition to increasing the thermal resistance up to 600 degrees Celsius, the strength also increases.
To get more acquainted with this product and get more details, you can read the article on asbestos refractory tape from the Pars Refractory website.

Asbestos refractory tape, as the oldest refractory tape used in the industry, has several features, among which the following can be mentioned:

High heat tolerance up to about 550 ° C
Low heat transfer
Impermeability in various conditions
Significant fiber cohesion and strength
Good mechanical properties and resistance to tension and abrasion
Maintain structure and dimensional stability at high temperatures
Asbestos refractory tape is available in various dimensions with a width of 15 to 50 mm.

Asbestos tapes, although limited to certain places, have many uses, some of the most prominent of which are discussed below:

Making gaskets for sealing
Insulation of motorhomes; This can be considered as the main reason for using asbestos tape and as mentioned before, another name for this product is engine room tape.
Insulation of industrial tanks, furnaces and boilers that are not in contact with humans or the environment.
Insulation of parts and equipment, in power plants, and fuel and oil stations
Petrochemical industry
Cement factory wall
In cases where it is not possible to use alternative refractory tapes for asbestos.

Also, due to the negative effects of asbestos on the environment and human health, one of which is lung cancer, scientists have begun to introduce suitable and cost-effective alternatives to asbestos tape.
