For most people, the word "rubber and plastic insulation material" is still very strange, but this does not affect its value, it is like a "willing ox", silently guarding the central air conditioning pipe, silently contribute to building energy conservation, is a low-key "invisible hero".


Although we can't see the figure of rubber insulation indoors, but when decorate construction, rubber insulation materials have been widely used, with more parts of the central air conditioning, construction, chemical industry, medicine, metallurgy, shipbuilding, vehicles, electrical appliances and other industries or departments of all kinds of cold and hot medium pipes, containers, can effectively reduce the cold and hot loss effect.

Nowadays, there are many kinds of rubber and plastic insulation materials on the market, and the quality is uneven. How to judge the quality of rubber and plastic insulation materials has become a problem that many friends are very concerned about. In fact, we can judge its quality comprehensively from the appearance of rubber and plastic insulation materials, thermal conductivity, wet resistance factor, fire rating, service life and other aspects.


1. See the appearance

First check the surface of rubber and plastic insulation material, if the surface color is uniform and shiny, the surface without bubbles, pitting, fine lines, peeling and other phenomena, showing a smooth, beautiful appearance, quality is good; On the contrary, if the surface color is dark and dumb, it is easy to appear small fine lines, and it is broken with a scratch, then the quality is poor.


2. Look at thermal conductivity

Thermal conductivity is the most basic performance index of rubber and plastic insulation materials, which determines the advantages and disadvantages of thermal insulation/cold insulation performance of materials. The smaller the thermal conductivity, the better the insulation/cooling performance of the material; On the contrary, the higher the thermal conductivity, the poor insulation/cooling performance of the material, but also cause a large amount of energy loss.


Uetersen rubber plastic thermal conductivity in the average temperature of 0℃, can be as low as 0.034W/M.K, in the same external conditions, the use of relatively thin thickness of the product, can achieve the same thermal insulation effect of traditional insulation materials.

3. Look at the moisture resistance factor

Moisture resistance factor is a factor to measure the resistance of adiabatic material to water vapor infiltration. The larger the μ value is, the stronger the resistance of the material to water vapor infiltration is, and the longer the service life is.


At present, the wet resistance factor of rubber and plastic insulation materials on the market rarely reaches more than 8000, You son rubber and plastic has a high wet resistance factor (μ≥10000), so as to ensure that the material has excellent water vapor permeability resistance, stable thermal conductivity in the process of use, prolong the service life of the material, reduce the operating cost of the system.


4. Look at the fire rating

According to the latest national standard GB8624, the fire rating of building materials can be divided into the following types: B1 class refractory, B2 class combustible, B3 flammable. In addition to the traditional inorganic materials on the market can achieve non-combustible, other products are below the B1 level, rubber and plastic insulation materials to achieve B1 refractory or quite difficult.


Uetersen rubber and plastic material has good flexibility and toughness, easy to deal with bending and irregular pipeline construction, and can save labor and materials; Superior to high elasticity, thus minimizing vibration and resonance in the use of chilled water and hot water pipes.

5. Look at the service life

Rubber and plastic insulation materials have excellent weather resistance, aging resistance, cold resistance, dry resistance, moisture resistance, ultraviolet resistance, ozone resistance, no deformation and other characteristics, the service life of the general rubber and plastic insulation materials on the market is mostly about 15 years, and good rubber and plastic insulation materials can be used for 25 years, longer than the service life of air conditioning.


In a word, the important value of rubber and plastic insulation materials lies in the perennial use of no deterioration, and itself can play a fire prevention, anti-perk. In low temperature and deep cold, underground engineering, flammable, explosive, damp and chemical erosion and other harsh environment, formaldehyde free, safe and reliable, durable, loved by the majority of consumers.


Learn the above five tricks, easily master the way to distinguish the quality of rubber and plastic insulation materials, I believe you can also!
