foam rubber insulation tape – To reduce the diffusion of water vapor to a minimum should be taken certain measures. When using insulating materials with low resistance to water vapor diffusion is necessary to create an effective vapor barrier. But arranging such protection in practice it is often very difficult. Furthermore, there is danger of mechanical damage , causing it to lose its protective properties . In such complex shaped parts as valves , elbows , valves , etc. very difficult, if not impossible, to create a protection against water vapor diffusion .
Systems supply cold insulation must be properly installed and sealed . Only correct mounting, providing high resistance to water vapor diffusion – is a special adhesive bonding insulation . And this weakness polyethylene foam . Polyethylene as the material lends itself to bonding , but the edges are glued seams bad. This is reflected in resistance to mechanical stress (low ) , and the resistance to water vapor diffusion with respect to a lower temperature. If the water vapor begins to penetrate through the glued seam on the surface of insulation will condense . This will lead to damage to the adhesive joint ( longitudinal or transverse) to the object begins to enter the air and water vapor , which would result in condensation or icing an object , and the use of such insulation lose meaning. In synthetic rubber glued seams are stronger than the material itself . You can check this by trying to break the two pieces glued together rubber : material rupture elsewhere , and self adhesive bonding withstand the load!
Protection against condensation is provided by a thickness of insulating layer , wherein the surface temperature above the dew point of the ambient air . Required insulation thickness is determined by the following variables :
Prevent condensation on the surface – the minimum requirement , which must comply with any low-temperature insulation materials made of foam rubber have high insulating properties and are designed in such a way that effectively prevents condensation even at the critical temperature . Using glue when installing insulation provides reliable and continuous connection joints . High flexibility material allows them to resist elastic deformation temperature , causing problems with joints using rigid insulating materials.
In addition to preventing condensation low temperature insulation shall perform the following functions :
Reducing heat loss ;
To ensure the necessary temperature of the substance ;
Preventing the formation of frost on pipelines and vessels.
It is important to insulation system retains its original properties for a long time .
Particular attention should be paid to the safety operation of the facility in the event of failure of insulation , which is very likely when using polyethylene. Unlike systems with hot carrier, which in the worst result would be an increase in heat loss in refrigeration may cause damage or break the entire installation and / or the purpose for which this insulation used : Defrosting , breakdown in process , simple production , the output of equipment failure , etc. As a result of non-pecuniary losses and economic damage may considerably exceed the “savings” from the use of cheaper insulation material .
Because refrigeration is often associated with the storage of food , insulation materials used in this area must be safe for human health , not affect the smell or taste of the food .
All brands of foam rubber supplied by our company are safe for human health and life , do not have an unpleasant odor and aesthetic.
Owing to its high flexibility foamed rubber is extremely easy to install . When insulating pipes of small diameter insulating tube can be easily mounted on them . Specific surface such as tanks , may also be isolated without any preparation . Possible error mounting easily compensated for by the flexibility of the material . Insulation performance can be easily checked at any time , since it is not hidden special coating.

For safe and reliable operation of cold water , air conditioning and refrigeration equipment and should only be used to lay the insulation of foamed synthetic rubber mounted with glue .
