With EMS-Grilamid TR 90, EMS-Chemie supplies the plastic that many ultra-light eyewear frames rely on when they have to survive daily bending, sweat, and sunshine without complaint. You do not see the material, but you feel it on your nose.

What EMS-Grilamid TR 90 is made for

EMS-Grilamid TR 90 is a transparent polyamide that EMS-Chemie positions as a high-performance material for thin, light yet tough components in eyewear, electronics, and precision parts. It combines low density with high flexibility, so frames spring back instead of snapping.

The material is designed to resist stress cracking from cosmetics, skin oils, and household chemicals, which typically attack ordinary plastics in daily use. It also offers good UV stability, an important point for sunglasses that live in harsh sunlight.

How it changes eyewear design

Eyewear manufacturers like EMS-Grilamid TR 90 because it allows very slim temples and bridges without feeling fragile in the hand. You notice it when glasses flex quietly as you slide them on, instead of creaking or feeling brittle.

Compared with classic acetate or metal, TR 90 enables lighter frames that sit more gently on the nose and ears, especially in sports and children’s models. Designers can also work with translucent or brightly colored finishes, because the base polymer is naturally clear.

Processing and sustainability aspects

For processors, EMS-Grilamid TR 90 runs on standard injection molding machines, with flow behavior suited to thin-walled parts and fine details. That keeps tooling and cycle times manageable, even for complex frame geometries or integrated hinges.

EMS-Chemie emphasizes that the material is free of BPA and plasticizers and can be recycled mechanically, depending on local systems. For brands that market eco-conscious collections, that is at least a step toward a more consistent sustainability story, even if it is not a biobased polymer.

Where EMS-Grilamid TR 90 shows its limits

Despite its strengths, EMS-Grilamid TR 90 is not a silver bullet. At very high continuous temperatures or in contact with certain aggressive solvents, more specialized engineering plastics can still be the better choice. EMS offers other Grivory and Grilon grades for those cases.

And because the material is a premium polyamide, frames produced with it can be more expensive than simple injection-molded plastics. For discount eyewear ranges, that cost hurdle can be a sobering factor.

What it means for EMS-Chemie

EMS-Grilamid TR 90 sits within EMS-Chemie’s High Performance Polymers business, the group’s core earnings driver. Every branded frame that chooses TR 90 over a commodity plastic strengthens the specialty positioning and pricing power of the Swiss company.

According to EMS-Chemie, its strategy is to focus on high-margin, application-specific materials and to exit low-margin standard products. EMS-Grilamid TR 90 fits that profile neatly as a tailored solution for demanding consumer and industrial uses.
