GEO MEMBRANE A geomembrane is very low permeability synthetic polymeric membrane liner or barrier used with any geotechnical engineering related material so as to control fluid migration in a human-made project, structure or system. They are made of (un)reinforced polymeric materials which are used to stabilize earth & secure landfills ensuring containment of hazardous or municipal wastes and their leachates. High-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) geomembranes are effective and affordable options in reservoirs for water storage. The composite geomembrane is a kind of geosynthetics which made of more than two kinds of materials such as geotextiles (or fiber glass mesh), polymers (such as PE geomembrane, EVA geomembrane) and so on. The main physical properties of geomembranes in the as- manufactured state are: Thickness – 60mil as standard (smooth sheet, textured, asperity height), Density, Melt flow index, Mass per unit area (weight), Vapor transmission (water and solvent) . HDPE geomembrane liner is the preferred product for lining projects. HDPE liner is resistant to many different solvents and are the most widely used geomembrane liner in the world. Although HDPE geomembrane is less flexible than LLDPE, it provides higher specific strength and can withstand higher temperatures. HDPE is known for its flexibility, chemical stability, and high strength-to-density ratio. HDPE offers a leak-free system via heat fusion joints. While PVC is stronger and stiffer material, it makes it suitable for direct burial and trenchless installation. Why Bajaj ? We make speciality masterbatches for HDPE) geomembrane liners, which are used primarily in landfill and other solid waste containment sites, and for mining and water containment applications. Our Premium range of Black, Colour & UV masterbatches are used in Pond liners while our fillers are used to economize the cost but not deteriorating the product quality . Being a well renowned masterbatch manufacturer for more than 3 decades we’ve established our footprints as a reliable supplier to the geosynthetic industry and has a broad range of colour , uv , black masterbatches & fillers that ensure adherence to any international standards. Unique features innovative Research and Development We’ve done continuous innovation in our RnD & state-of-the art technology in manufacturing masterbatches for speciality applications like geosynthetics, ensuring better performance of their structures and reduced long-term maintenance. reliability and long-term sustainability Since the polymer and masterbatch system used in Geo memberane is very much critical to the performance, reliability and long-term sustainability of products we ensure that our products meets the customer’s specifications not only imparting colour but also it does the role of value addition by retaining functional properties in combination with the polymer . good dispersion Our masterbatches besides providing very good dispersion but also delivers superior performance, as we offer more as a solution (ie) stabilization package that provides excellent long-term thermal stability and life prediction. exceed international standards The right selection of anti-oxidants & UV additives is critical to maintaining the mechanical properties of geosynthetics. We do have expertise in offering additive packages & their incorporation into polymers to produce highly-technical solutions for geosynthetics ultimate durability The ultimate durability of geosynthetic compounds used in solid waste landfill, bunding and chemical separation, is a function of the stress-cracking resistance, the effectiveness of its antioxidation additives, the stresses generated in the geosynthetic applications during installation operation, and the stress-relaxation rate. good weldability Ensuring good weldability, by eliminating the migration of additives that can cause fusion welding problems, requires careful selection of the correct masterbatch carrier system and additive package, we always do that . optimal balance of mechanical properties Our masterbatches are formulated to provide the optimal balance of mechanical properties, environmental stress cracking, tensile strength, flexural strength, impact, hardness, creep resistance, heat deflection temperature, hysteresis and thermal mechanical performance, to give the complete solution for geo membranes application.

Poor lay flat propertiesA geomembrane produced without camber will be less likely to wrinkle during installation than one with camber. Eliminating camber depends on the alignment and winding of geomembranes DETERIORATION OF MEMBRANES AFTER EXPOSURELack of crystallinity & poor ESCR propertiesTo add more UV & Premium Black MB to HDPE resin to prevent polymer degradation & heat ageing occurring due to solar radiation Lack of sufficient OIT ( oxidation induction time).Addition of Antioxidant in the resin at proper level for heat stabilization facilitates long term sustenance & durability.
