What Is TR90 Frame?
TR90, or Grilamid TR90, is a thermoplastic material first created at the Swiss EMS company. It was initially a transparent granular polymer with some remarkable features. Among these are low density, good chemical resistance, low moisture absorption, high distortion temperature, and incredible flexibility.
Its exceptional characteristics made it the perfect material for many purposes, including eyewear. Over recent years, TR90 frame sunglasses are becoming incredibly popular for the superior benefits they offer.
So what’s so special in TR90 frame sunglasses that everyone’s going crazy over? Let’s check out the benefits before you pick your first TR90 sunglasses.
1. Lightweight
The density of superior quality TR90 material is between 1.14 to 1.15 kg/m3. At this density, they’re even lighter than the regular nylon! It makes them one of the lightest frames in the market, substantially lifting the burden off your nose and ears of carrying the sunglasses all day.
2. Impact-resistant
If you're not too confident with your grip and guilty of dropping things often, TR90 sunglasses are the ones for you! Since the material is flexible, it's much more resilient to damage than other frames. Rest assured, it won't break, bend or even show a scratch no matter how many times you drop it!
3. High heat resistance
TR90 frames can withstand temperatures as high as 400 degrees. They're not going to melt or burn, no matter what you put them through.
4. Vast selection of colors and styles
While the regular plastic frames aren't so versatile, TR90 frames are available in philanthropy of colors and styles.
