Polymers of natural origin

    In an increasingly technological world, where high performance and quality are required in the most diverse sectors, nature comes back to help us. This is how thanks to polymers of natural origin it is possible to produce sheets able to offer those technical characteristics necessary to produce visors for optical applications.

  • Cellulose Acetate (CA) – trademark Xelox-L

    Cellulose is a natural polymer from vegetable sources. Cellulose Acetate (CA) is obtained by reacting cellulose with acetic anhydride. Different plasticizers are then added to Cellulose Acetate to improve their physical characteristics and workability. Through sophisticated extrusion and press polishing processes we obtain sheets with high optical quality suitable for various technical and protective purposes.

  • Cellulose Propionate (CP) – trademark Worblex

    Cellulose Propionate (CP) is obtained by reacting cellulose, a natural polymer which represents the backbone of the whole plant kingdom, with a mix of acetic anhydride and propionic anhydride.
    The physical properties and workability of cellulose propionate are then improved by the addition of plasticizers. We are able to produce sheets with high optical quality which are suitable for a variety of technical and protective purposes through advanced extrusion and press polishing processes.

  • Cellulose TriAcetate (CTA) – trademark Xelox-L

    Cellulose TriAcetate (CTA) is produced by reacting cellulose with acetic anhydride. It then undergoes a sophisticated casting processes which allows to produce sheets with high optical quality which are suitable for a variety of technical and protective purposes.

    There TriAcetate sheets are polarized.

Superior anti-fog performance

Whether you’re working or driving or swimming you need to be able to see clearly. A fogged-up vision can significantly compromise several daily activities and, in many cases, can increase the risk of injury.
That’s why an anti-fog system is needed to help you to achieve a clearer vision thus making sure that you can carry out your activities with precision and accuracy.
Mazzucchelli has developed in its laboratories an anti-fog system which will prevent its products from fogging up guaranteeing a protection which will last forever.

How is anti-fog performance achieved and what advantages does it give to your products?

What is Bioplastic?

The exposure of the Cellulose Acetate, Cellulose TriAcetate and Cellulose Propionate sheets to a multi-step chemical reaction makes their surface resistant to fogging which becomes an inherent property of the sheets. The hydrophilic surface enables the sheets to absorb moisture vapor without fogging up and leaving a clear view through.

Thanks to this process the following results can be achieved:

  • For the standard grade a fog-free time of ≥ 30 seconds is guaranteed in accordance to ISO 16321-1 7.13, ISO 18527-1 14.2 and ISO 18527-3 9.4.
  • For special applications we can offer our “super-anti-fog” grade with improved fog-free time of ≥ 120 seconds.
  • The anti-fog performance lasts forever.

Here is a list of the features that make our Cellulose Acetate, Cellulose TriAcetate and Cellulose Propionate sheets so effective for eye protection in optical quality:

  • Light transmittance up to 90%
  • UV protection at 360 nm, 380 nm and 400 nm
  • Good mechanical resilience at low temperatures
  • Good resistance to chemicals and solvents
  • Gas welding filters up to shade 5, with or without IR protection up to 1400 nm
  • Laser protection filters
  • Blue light blockers
  • Wide range of colour tones
  • Highly active photochromic colours
  • Polarized colours
