Frames made of TR90

TR90 is an advanced polymer frequently used in the manufacture of frames for sunglasses and prescription glasses, known for its exceptional combination of durability and flexibility . This material, derived from nylon, has several technical characteristics that make it ideal for this type of applications.

First, its lightness is one of the most notable properties of the TR90. This material is extremely light, which translates into superior comfort for the user, allowing prolonged use of the glasses without causing facial fatigue.

The flexibility of the TR90 is another crucial feature. Frames made from this polymer can bend and twist without breaking, significantly increasing their lifespan. This bending ability not only improves the durability of the glasses, but also allows them to better fit different face shapes, providing a more comfortable and secure fit.

In terms of impact resistance, the TR90 excels. This material can absorb bumps and falls without breaking, offering additional protection to the lenses and increasing user safety. This property is especially beneficial in sports glasses, where impact resistance is crucial.



TR90 is also remarkably resistant to chemicals . It does not easily degrade when it comes into contact with substances such as sweat, cosmetics or cleaning products, ensuring that the frames maintain their integrity and appearance over time.

In addition, TR90 has excellent thermal stability . It maintains its physical properties and shape even when exposed to extreme temperatures, both hot and cold. This is particularly important in variable climates or for outdoor activities.

Due to these properties, TR90 has established itself as a material of choice in the optical industry, especially for high-quality and sports glasses frames. Its combination of lightness, flexibility, impact resistance, chemical resistance and thermal stability makes it a superior option for those looking for durability and comfort in their glasses.
