d55ddjikjkx.jpegMegaplast India Pvt Ltd (Megaplast) BASF Chimassorb range of light stabilizers is India's leading manufacturer of polyethylene products for the production of non-woven geotextiles for the construction of national highways. The additive package plays an important role in stabilizing the geotextile production process and extending its service life.

Senior Vice President, Performance Chemicals, BASF Asia Pacific "Nonwoven geotextiles are a high-performance material used to improve foundation soils for above ground structures and also help prevent climate erosion." civil engineering projects." Althoff said: 'Our plastic additives for harsh processing conditions extend the uptime of the production process, make processing more reliable and reduce maintenance costs. '

BASF not only provided Megaplast with the right light stabilizer package for its products, but also helped interpret the technical data results. During testing, BASF helped the customer try different formulations so they could choose the best balance between cost and performance.

One of the most important benefits of geotextiles in road construction is maintaining separation between layers of soil particles of different sizes. Geotextiles help limit the flow of water and fine soil particles into gravel, which would otherwise significantly reduce the strength of the gravel. The use of geotextiles in road construction improves the quality of roads, extends their service life and reduces maintenance costs. The application is also widely used in canal lining, tunnel lining and landfills.

This type of geomembrane is typically manufactured from high density polyethylene made (HDPE). To make these materials, the HDPE material is spun into filaments and then thermally bonded without the use of adhesives. Light stabilizers typically include process stabilizers, which are used to protect the polymer during extrusion, as well as UV stabilizers and heat stabilizers, which are used to prevent heat and light degradation.

Global demand for geomembrane materials is expected to increase significantly in the coming years. The biggest development in this sector will take place in India due to the large infrastructure projects that are currently underway. The World Bank has made it mandatory to use geotextiles/geomembranes in all infrastructure projects financed by it.
