INSULATION


Elastomeric insulation with PET core


P


ipe brackets represent a potential weak point in insulation systems. If the pipe is not thermally


isolated from the pipe bracket, thermal bridges occur and condensation can form. This leads to increased energy losses, a higher risk of corrosion and expensive secondary damage. Together with the adjoining Armaflex insulation, pipe supports made of flexible elastomeric foam and load- bearing polyethylene terephthalate (PET) segments offer a high resistance to water-vapour transmission and reliable prevention of heat loss.


Armafix Ecolight is made using environmentally friendly load-bearing segments from industrially foamed recycled PET bottles. Polyethylene


terephthalate is lightweight and has a high mechanical strength in combination with residual flexibility and a maximum service life.


Furthermore, PET has very good insulation properties: the material has a closed-cell structure, low thermal conductivity (23°C ≤ 0.033 W/mK) and, with a density of 100 kg/m³, PET weighs less than polyurethane (140 - 145 kg/ m³).


The PET segments can be completely recycled at the end of their service life, with all production scrap flowing back into new PET blocks. PET also has an excellent environmental performance requiring over 60% less energy for its production than polyurethane and releasing over 80% less CO2


.


Depending on the diameter of the pipe, the heat loss on an uninsulated pipe bracket (on the left) can be equivalent to the heat loss from up to one metre of uninsulated pipe.
