Laser Marking Tritan™

Tritan™ is a copolyester which means that acids and chemicals have been added to the base plastic to make the new material. It has emerged as a groundbreaking material for a range of industries thanks to its clarity, durability and versatility.

Transparency
Tritan™ material boasts exceptional clarity, closely resembling the appearance of glass. This transparency makes it an ideal choice for products where aesthetics and visibility are crucial, as it allows for a clear view of the contents within.

Impact Resistant
Tritan™ is highly durable and can withstand rough handling without cracking or breaking. It makes it an excellent choice for applications that require products to endure challenging environments.

Chemical Resistance
Tritan™ has a high resistance to a range of chemicals, including many cleaning agents and acids.

Resistant to Heat
Tritan™ can withstand relatively high temperatures without fear of warping or losing its structural integrity.

Lightweight
Tritan™ has outstanding strength to weight ratio characteristics and is lighter than glass, making it a practical solution for applications where weight reduction is paramount.

Food Safe
Tritan™ is a BPA-free plastic and is considered safe for food and beverage contact. Its chemical stability ensures that it won’t leach harmful substances into consumables.

Tritan does not engrave or mark well by 10.6µm or 1µm laser wavelengths, however it engraves beautifully by UV. UV lasers work a little differently to CO2 or Fibre as they do not damage the materials surrounding surface, using a far lower power form of marking. Working at a wavelength of 355nm, UV lasers exhibit a significantly shorter wavelength compared to the other technologies in this context. Employing a method referred to as “cold processing,” UV lasers emit high-energy photons within the ultraviolet spectrum, which effectively disrupt the chemical bonds within the material. This disruption leads to non-thermal damage to the material, meaning it will not generate any heat-related deformations in the inner layers and nearby areas of the target area.

When using a UV laser to mark Tritan™ the result is similar to that of sandblasted glass, leaving a crisp, clear and legible white mark.
