    Taglus PU Flex

    Smartest material properties and enhanced esthetics

    Taglus® PU Flex is a homogeneous single-layered polyurethane sheet that consists of linear polymeric chains made of alternating flexible and rigid segments. It is a high-performance aligner and retainer material that provides excellent flexibility, strength, and durability, while also providing comfort for the wearer.

  • properties
    • Highly flexible :Unique formulation results in resulting in higher toughness yet more flexibility
    • Comfortable and durable :High value of elongation at break reduces the risk of aligner cracks
    • Brilliant wear and tear resistance : Designed for long term wear to withstand tooth forces
    • Orthodontic forces :Generates 20% more initial forces Vs other PU materials



In applications where plastic films are designed to withstand orthodontic forces in an aligner, the mechanical properties of polymers namely Strength, Stiness & Toughness play a vital role. Such properties of Taglus® PU Flex sheets when investigated using standardized test methods, e.g. tensile stress as per ASTM D 638: 2014 by briefly applying load in one direction the approximate results and values observed during such test, demonstrate that Taglus® PU Flex has the highest tensile stress at the break in its class approximately equal to 68 MPa and the Flexural stress as per ASTM D 790 is extremely high to approximately about 90 Mpa. So, it is an optimal balance of rigidity with elasticity. The test was performed by a NABL accredited Laboratory complying with ISO/IEC 17025 Laboratory Management System.


Taglus® PU Flex sheets have a very high value of elongation at break. With an approximate value of 270%, the material can stretch up to 270 percent of its original dimensions before it breaks, this eliminates the worries of aligner cracking


Taglus® PU Flex samples tested at temperature 37 with sample width 0.5”, length 2” along with UTM instrument parameters as span 1”, pressure head 5mm with pressure 0.5mm, withhold time initial, 24h, 48h, 72h, and 120h, for a range of orthodontic forces from 0.9 to 1.5N it was found that the stress relaxation rate was as low as 0.0172 N/h to 0.0074 N/h for a stress residual ratio of 80.3% to a drop 31.45%. This gives 20% more initial force than other PU materials which would be an optimal orthodontic force required to move the teeth from their initial position as per the law of inertia and maintains 50% more orthodontic force over its functional time.
