RoundWhat is TR90?
TR90 is a thermoplastic polyamide material developed by EMS in Switzerland for high-performance eyewear. It is known for being lightweight, flexible, and impact-resistant. TR90 frames can bend under pressure and return to their original shape, which makes them popular for sport, kids, and active lifestyle eyewear. For B2B buyers, TR90 offers a strong balance of durability, comfort, and cost. READSUN Optical produces custom TR90 frames for wholesale and OEM/ODM programs.
TR90 Frames Explained for Eyewear Brands and Importers
What is TR90 glasses material? In simple terms, TR90 is a memory plastic. It belongs to the thermoplastic polyamide family and is produced through injection molding. The material is heated, injected into a mold, and cooled into the final frame shape.
The name TR90 comes from the material's memory effect. When the frame is bent, it returns to its original shape instead of breaking. This is why TR90 frames are often used for children, sport, and outdoor eyewear, where flexibility and impact resistance matter most.
| Property | TR90 | Cellulose Acetate |
|---|---|---|
| Base material | Thermoplastic polyamide | Plant-based cellulose acetate |
| Production | Injection molding | Sheet cutting and polishing |
| Weight | Very light | Medium to heavy |
| Flexibility | High; memory shape return | Low; rigid but adjustable with heat |
| Impact resistance | High | Medium |
| Color range | Solid colors, matte and gloss finishes | Rich layered, transparent, tortoiseshell |
| Repairability | Limited; not easily polished or reshaped | Good; can be polished and heated |
| Best for | Sport, kids, active lifestyle, value lines | Fashion, premium, private label |
This comparison explains the common TR90 vs acetate question. TR90 wins on flexibility, weight, and impact resistance. Acetate wins on color depth, premium feel, and repairability. Many brands carry both materials to cover different market segments.
TR90 Frames: What B2B Buyers Should Check
For importers and brands, tr90 optical frames are a strong option for value and performance segments. The material is cost-effective at volume, and its flexibility reduces breakage and returns. The table below summarizes the key factors buyers should confirm.
| Factor | What to check | Why it matters |
|---|---|---|
| Material grade | Genuine TR90 vs generic nylon or polyamide | Affects flexibility, color stability, and durability |
| Mold quality | Steel mold condition and precision | Affects surface finish, fit, and consistency |
| Frame weight | Finished weight per frame | Affects comfort for kids and long wear |
| Hinge type | Standard, spring, or barrel | Affects durability and repair rate |
| Color and finish | Solid, matte, gloss, two-tone | Affects style positioning and market demand |
| Nose pad | Integrated, fixed, or adjustable | Affects comfort and fit across face shapes |
| Compliance | Material safety, nickel release for metal parts | Required for EU and other regulated markets |
| MOQ | Per model and per color | Injection molds raise upfront cost and MOQ |
Buyers should also confirm whether the factory uses genuine TR90 or a lower-cost substitute. Some suppliers describe generic nylon or polyamide as TR90. Genuine TR90 has better memory, color stability, and impact performance.
