Thermally Inactive Reflective Liner material is a 3layer co-ertruded Geomembrane. The product core and inferior layer remain black which doesn`t affect any technical properties of the liner. By changing the composition of the superior layer the addition of a pure white pigment composed of UV additives, Tianhai created a product that offers additional on-site benefits suitable for various applications.
Geomembranes were created to contain solids and fluids for very long periods. As such, they need to have high endurance properties. One of the best additives for plastics to resist to UV degradation is carbon black. However, this results in having black geomembrane. Black geomembrane will get very hot when exposed to sunlight because of its high expansion/contraction coefficient.
Tianhai innovated in developing a new reflective geomembrane. While having obvious aesthetic advantages, the reflective liner will also reflect the sunlight and reduce the temperature of the geomembrane. This reduction in temperature will reduce the expansion/contraction of the geomembrane which will allow for an easier installation and reduce wrinkles in the liner. For composite liner systems, reducing the wrinkles will increase the intimate contact between the liner and the low permeability sub layer which will lead to a more efficient impermeable system. It will also slow down the aging process and increase its service life.
Another advantage of the reflective geomembrane is the contrast between the white surface layer and the black core of the liner. This allows easy identification of visual defects as they will be more apparent than on traditional black geomembranes.
While reflective geomembranes seem to only offer aesthetical advantages, as expressed above, significant benefits result from using reflective geomembrane over traditional black geomembrane.
