Optyl - Optyl is a material patented by Safilo and is currently produced and used exclusively by the Safilo Group. It is a thermosetting plastic which, as well as having outstanding physical and chemical properties, guarantees excellent surface finish and higher strength than conventional thermo-plastics (acetate, propionate, etc.) It's light weight, flexible, heat resititant and contains no plastifiers. Other advantages of wearing an Optyl Frame is that they are Hypo-allergenic, resistant to perspiration and cosmetics, and when heated to 120'C they can be adjusted to fit your face, and then easily returned to its original shape once heated again.
Acetate - Cellulose acetate is one of the most versatile of all plastic frame materials and the most commonly used. It is obtained from cotton flocks and wood pulp, and it can have a great variety of colours, with either a single colour or multiple colours. Acetate is a very adapatable and is highly resistant to chemicals. Other advantages of Acetate is that the frames are easy to adapt when need be and is a hypo-allergenic material.
Polyamide (nylon) - Safilo uses two kinds of polyamide (nylon) materials: TROGAMID and GRILAMID. Both these plastic materials have a high performance and do not cause any type of allergies.
Grilamid - Grilamid is a thermoplastic material for injection moulding. Research in the field of plastics has recently led to the use of Grilamid TR 90 LX, a grade of nylon that meets all the requirements needed for a material used for spectacle frames. Grilamid is an extremely strong, very lightweight, os easy to heat and shape if needed. Another advantage of having grilamid frame is that they are resisitane to perspirations, cosmetics and detergants
