    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.




have any question

Is it clinically tested? How safe is it to use in the mouth?

Taglus Premium sheet passes biocompatibility testing namely Skin Sensitization, in vitro Cytotoxicity and Skin Irritation test as a regulatory requirement for demonstrating the preclinical safety of medical devices, this is evaluated in line with the standard guideline, ISO 10993-1:2018(E), Biological evaluation of medical devices – Part 1, vide UL Project #4788877994 as per document published by the US FDA “Use of International Standard ISO 10993-1, “Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process” can be accessed at ttps://www.fda.gov/media/85865/download. Taglus Premium is “FDA compliant” means that a material meets all of the FDA’s guidelines for safety. It is made from PET which a plastic is recommended by FDA under 21CFR177.1630 guidelines for Polyethylene phthalate polymers. Being a BPA makes it a safe to use product.

How much effective tooth movement is possible when used for aligners?

Taglus premium is made specifically for aligner fabrication. It may create a gentle but consistent force leading to a tooth movement of approximately up to 0.25 mm per aligner in 7 to 15 days depending on the recommendation of certified Orthodontists

Do they offer any advantage when used for fabrication of surgical splints?

Due to its property of binding to all types of light and heat cured acrylics and the ability to adapt precisely to the model under pressure it is a very popular material used to fabricate surgical splints. Moreover, splints made from thermoformed. Taglus premium have greater stability and consistently high quality due to zero curing shrinkage.

What are the various commercially available dimensions and thicknesses of these sheets?

Available in a wide variety of thickness and shapes refer Table. Customized “Run-to-Size” dimensions are also available.

What advantage does PETG material have over the traditional PET material used in other thermoformed/ thermoplastic sheets?

Taglus premium is manufactured by the addition of special grade glycol to PET (polyethylene terephthalate glycol). This gives it three distinct advantages over its competitors:

  • Elimination of the hazing effect that occurs during heating.
  • Prevention of undesired crystallization.
  • The inner walls of the aligner and retainer are transformed into a softer, more comfortable material for the patient.

What are working codes for Taglus Premium?

Taglus Premium can be used with several commercially available thermoforming units. For working codes, kindly refer (brochure link)

What does the peel away mask do?

The sheet is covered with an ultra-thin layer of protective covering. This peel-away masking does not get removed during thermoforming procedure. It shields the retainer from getting exposed to dust and other substances that can affect its surface. Thus the optical clarity is preserved forming an ultra-clear final product.

Is it easily available all over?

Yes, Taglus Premium sheets have an extensive global distribution. Kindly contact us on info@taglus.com for more details

What is the shelf life of taglus premium

The shelf life is 03 years subject to non-opening of vacuum-packed packaging.
