Tenite™ cellulosics

Tenite cellulosics offer exceptional chemical resistance due to their innate ability to release stress. Tenite acetate and propionate remain at the forefront of the industry, offering numerous advantages, including:

Clear optics — Pressed, polished acetate sheet sets the standard for clear and pristine optics. 

Scratch resistance — Cellulose acetate and cellulose acetate propionate (CAP) have industry-best scratch resistance. 

Antifog advantage — Natural antifog resistance makes cellulosics a clear choice for antifog and other coatings. 

Thin safety shields — CAP allows injection molding of safety shields that are half the thickness of polycarbonate (PC). 

Efficient processing — Sheets can be processed at 20% lower temperatures and dried in 25% less time compared with other popular polymers.

Made from trees — Tenite cellulosics are made from trees harvested from sustainably managed forests.  

For every pound of Tenite produced, 40% to 50% by weight is renewable content.*

  • Equal or superior to polycarbonate (PC)
  • Easier to fabricate than PC
  • Lower density than PC
  • Saves energy and time — thermoforms at lower temperatures and no annealing required
