Thermal Insulator is used in pipes, tanks, vents, and surfaces of the heating and cooling systems of buildings in order to reduce heat loss and energy consumption, humidity penetration, and spread of noise. Insulators are used in many industries such as petrochemical, petroleum, chemical, automobile, shipbuilding, aircraft, power generation, and medical industries.
Insulator has gone a long way, traveling from mineral Insulators such as glass wool and mineral wool to a newer generation of Insulators called polymer Insulators. Polymer Insulators offer many benefits such as easy implementation, flexibility, lightness, and more.

Thermal insulators are classified based on their material, function, shape, and usage.
1.Elastomeric insulators:
close cellular elastomeric insulators which are a new generation of heat/cold insulators are used to prevent the problems of saving energy. They come in different thicknesses and types of roll and pipe. These insulators cover steel and copper pipes. These insulators are of a great role in industry and construction because of their unique physical and mechanical features. In the following, these features are briefly discussed
2.Thermal continuum:the physical and chemical features of these insulators do not change in a temperature between 70 to 120 C. within this thermal limit; the insulator does not produce poisonous gases and keeps its insulating feature.
3.Heat transfer factor:
since the cellular structure of these insulators does not have broaches, the heat transfer factor in 0’C is equal to 0.032 w/MK. This property is constantly reserved. Also, the broach less cellular structure prevents condensing phenomena.
4.Steam penetration factor:
the penetration of steam into the traditional insulators lessened their efficiency. In elastomeric insulators, the penetration rate decreases five times. Therefore, the insulating feature remains for a long time.
5.Burning:
these insulators are fire-proof and prevent the fire from spreading.
6.Sound insulation:
This category of insulators is usually an insulated sound up to 32 DB.
7.Density:
since the air molecules are trapped while this insulator is molded, the density of the material reduces which leads to less heat transfer.
8.Clean technology:
elastomeric insulators produce less environmental pollution than their counterparts. They also work for a longer period which in turn reduces pollution.
9.Elasticity:
elastomeric insulators are elastic and flexible. So they are easily and effectively used in T and L surfaces where installing insulators is difficult.
10.In order to estimate the thickness of the required insulator, different factors have to be considered10. The thermal gap between the liquid and the environment, heat transfer factor, kind, and a cover of the insulator.
Bear in mind the following when selecting insulation materials:
A.The temperature difference between the two sides of the insulator;
B.Coefficient of thermal conductivity;
C.The material and its cover layer.
The type of thermal insulator depends on ambient temperature, safety, environmental conditions, and the price. The thickness of the thermal insulator must be economically selected, meaning that energy loss should be prevented with the thinnest possible insulation. The main thermal insulation materials include meager concrete (gas, foam, and other porous concretes), light aggregates, paper and aluminum, rock wool, pressed Styrofoam, fiberboards, mineral fibers, mineral wool, glass wool, sponge glass, pumice, perlite, light plasterboards with or without aluminum cover, plastics, hollow stems, and wood wool.
