Typar vs Other Geotextiles Performance: Typar offers benefits of high tensile strength of woven geotextile as well as elongation of needle punch geotextile making it the most versatile geotextile.
DuPontTM Typar® SF is a thin, thermally bonded, water-permeable nonwoven geotextile made of 100% continuous polypropylene filaments.
DuPontTM Typar® SF is an isotropic material, which means that its physical properties are the same in all directions. This mirrors the stresses and strains of a typical separation application.
DuPont™ Typar® SF has a high tensile strength, a high elongation, and also a high initial modulus which is the ideal combination of properties for geosynthetic applications (for comparison see also table).DuPontTM Typar® SF offers an exceptionally high energy absorption potential combined with a high initial modulus
Concept of energy absorption is represented by the area below the stress-strain curve. Products with large area indicates higher resistance to damage during installation.
Typar vs Other Geotextiles Performance: Typically stress at 5% strain is considered to determine the initial modulus. As showed in the graph, Typar has a high initial modulus resulting in higher capacity to absorb external stress and low deformation. Road pavements underlain with Typar has excellent resistance to rutting.
