I have never worked with the material and was wondering what your expereience with it is. It looks very durable but I wonder how it adjusts. Thanks for the help!

Inherited a line of Kaenons with my new optical...sold a few but nothing to report on the frame plastic.
The lens material SR-91 sounds interesting. (I've asked for white papers, but so far I seem to be California Dreaming.) The old brochure advertizes 1.56 with an Abbe value of 42...sounds pretty comporable to Trivex but even thinner. Sounds promising, but I'm still waiting to see...
Regarding adjusting, it depends upon if there is a core wire. If there is, you can do some adjustment. If not, which is most of the frames I have seen, it is very difficult. Be careful applying heat as you can easily damage the finish and if you are not careful, you can cause irreversible damage to the shape, especially the temples. Many have combination temples with a material that can be adjusted around the ears.
The TR-90 I have seen has the finish applied over the material. The frame itself is durable, however the finish can wear off, especially where it makes contact with the skin. TR-90 is a lightweight, very comfortable material. It is very inexpensive and is very popular in Korea and China. We sell some TR-90 frames and the better factories (especially in Korea) can do some pretty interesting things with the finish. I have a pair I wear personally and really like them. You can create pretty much any design or color. There are other injection materials such as ultem that are becoming popular. I have also seen TR-90 with acetate overlays manufactured in Korea. TR-90 is a very flexible and comfortable frame material. If made from a factory that can do a nice finish job, the frames are a terrific value. Unfortunately, too many factories make super cheap TR-90 frames which hurts the reputation of this frame material.

In this case, looks are very deceiving. looks durable, wears like crap.
I've had back luck with paint chipping from simple lens insertion.
The dolabany line has a slew of TR-90 frames. I haven't had any trouble with it. It's adjustable with heat and stays put. Its lightweight. Nothing bad to say really.
TR-90 is old hat. Ultem is the new black.
I've got both TR-90 and Ultem frames available. Sold a pair of each, the TR-90 came back as "uncomfortable to wear" and even after several adjustments, customer was never really thrilled about it.
*shrug*
Every time I use or mention TR-90 it makes me think of the old Roland TR-909 drum machine. I sometimes even call TR-90 TR-909 by accident. #musicianproblems
I'm Andrew Hamm and I approve this message.
At least they didn't call it TRS-80...
