Difference between acrylic lenses and PC lenses

Difference between acrylic lenses and PC lenses

Method 1 burning

1, acrylic panels are separated into: extrusion plate and casting plate, extrusion plate identification is, transparency number. With the original method of identification, fire extinguished, extinguished when the flame is clear, no smoke, bubbles, fire can be pulled out of the filament. Casting plate identification is: higher transparency, extinguished by fire, no smoke, bubbles, there is a squeak, no silk when extinguished;

2, PC endurance board, identification is: high transparency, good resistance to blow, not broken, extinguished with fire is not burned at all, flame retardant, and will come out of the department of black smoke;

Method 2, impact resistance comparison:

PC lenses at the time of reaching 2cm thickness, his impact resistance can withstand a bullet, but the impact resistance of acrylic lenses? If the same 2cm thickness of acrylic lenses, in the same circumstances for testing, the bullet can be shot through, according to the two tests for comparison, the PC lens impact resistance is stronger than the acrylic lens.

Method 3, light transmission comparison:

PC lenses are currently made through the production of light transmission performance of about 90%, but the light transmission rate of acrylic lenses is about 92%, in comparison, acrylic lenses light transmission effect is relatively higher than the PC lens light transmission rate, but in real life and production, we almost do not care about such a subtle difference when the light transmission rate reaches 90% and more than 90% after the light transmission rate can reach our production and use requirements. After the light transmittance reaches 90% and above, the light transmittance can meet the requirement of our production.

Method 4, use comparison:

Acrylic lenses usually we will use in the window of electronic products, such as bluetooth speaker acrylic lens window, bluetooth speaker acrylic lens base plate, there are a variety of other uses, PC lenses are more used in the eye lenses, whether to prevent external damage, or nearsightedness, or farsightedness, at this time we can be carried out to wear the PC lenses, or PC lenses used in aerospace, or PC lenses used in aerospace, because of its high hardness, so in aerospace and aviation. Because of its high hardness, PC lenses are preferred in aerospace.
