TR90 Frames And Plate Frames Which Material Is Better?

What are the common problems you should have when choosing eyeglasses frames? With the vigorous promotion of the field of glasses, glass frame manufacturers have found that more and more materials are applied to the top of the glass frame. After all, the frame is wearing on the nose, the net weight is not the same. What may feel in the short term, but in the long term, it is very easy to cause pressure on our nose. Style color is the main external expression, and material characteristics are more comfortable.
Plate glasses frame is dedicated to many fashion trend personnel and the pursuit of a perfect and exquisite life of the students, especially young women. At this stage, most of the plate eyeglass frame components are acetate fiber, but also a very small number of high-end eyeglass frames are propionic chemical fibers, so it is not easy to deform and discolor, good texture, strong and durable characteristics, high strength, good smoothness, and the integration of steel skin improves the solid characteristics, and the style is beautiful, durable, and beloved by everyone.
TR90 eyeglass frame is a memory ability of fiber material eyeglass frame, no chemical residues released, in line with the European provisions on food grade raw materials, is the most popular international lightweight eyeglass frame at this stage. TR90 frames have the characteristics of super ductility, collision resistance and wear resistance, and poor friction resistance, which can reasonably avoid the damage caused by the cracking and friction of the eyeglass frames on the eyes and face during fitness exercises. Because of its specific molecular formula, good resistance, it is not easy to deform in a high temperature natural environment, can withstand 350 degrees high temperature in a short time, and is not easy to melt and ignite. And TR90 eyeglass frame surface wetting, the relative density of 1.14-1.15, will be suspended in salt water, lighter than other plastic eyeglass frames, less than half of the net weight of the plate frame, is 85% of polyester raw materials, can reduce the nose bone, ear pressure, suitable for teenagers and children.
One: What are the materials of TR90 frames and plate eye frames?
TR90 frames, also known as plastic titanium, is a kind of optical frame made of fiber material with memory ability, about half of the net weight of the plate frame, ISO180/IC: >125kg/m2 ductility, to reasonably avoid damage to the eyes caused by collision during fitness exercise.
Plate selection of new technology of plastic memory plate production and manufacturing, at this stage of the glass frame manufacturers of plate components are mostly acetate fiber, but also a very small number of high-end glass frames are hexacidated chemical fiber. The acetate fiber plate class is divided into injection molding type and pressure grinding and polishing type, injection molding type is made of mold irrigation, but at this stage most of the plate glasses are pressed grinding and polishing production.
Two: The advantages of TR90 frames
1. Light weight, collision resistance, heat resistance: 350 degrees of high temperature in a short time, ISO527: deformation resistance index value of 625kg/cm2. Not easy to melt and ignite. The frame is not easy to deform and discolor, so that the frame can be worn for a longer time.
2. Safety: No organic chemical residues are released, in line with European regulations on food-grade stainless steel raw materials.
3. Bright color: the color is more beautiful than the general plastic architecture.
Three: The advantages of plate spectacle frames
1. High strength, good smoothness, integration with steel to enhance the solid characteristics, and the style is beautiful and generous, not easy to deformation and discoloration, durable.
2. With a certain ductility, when the pressure is released after a little hard bending or straining, the shape memory plate will return to normal.
3. It is not easy to ignite, almost not affected by direct ultraviolet light and discoloration, great strength and smoothness are good, and it is not easy to deform after wearing.
