In selecting materials, in addition to paying attention to the price, we should also have a certain understanding of its type and performance, and avoid weaknesses to find more suitable materials. In this article, we will introduce the differences between acrylic and PC boards, and explain the characteristics of the two materials, endurance board and plexiglass.
The basic materials of PCC endurance board and acrylic board are different. Acrylic is polymerized from "methyl methacrylate monomer MMA. Or acrylic granules are extruded through a plate extruder. PC board is made of polycarbonate as the main component and uses co-extrusion technology CO- EXTRUSION.
Acrylic is relatively brittle. The resistance to impact is not as good as that of an endurance board. Hitting an acrylic with a hammer will break it, and the endurance board will not. Surface light transmittance. The new material endurance board has high light transmittance and looks very transparent. Acrylic is a bit hazy. And acrylic is easy to age, and the endurance board can be made anti-aging. In the sun, the light reflected by the PC endurance board is very horizontal and can be seen by the naked eye.
Advantages and disadvantages of acrylic board:
1.Advantages of acrylic board
(1) Excellent weather resistance: the adaptability of acrylic sheet is very good; its adaptability to the natural environment is very strong. Even if it is exposed to sunlight and wind and rain for a long time, it will not change its performance; it has good anti-aging performance; it can be used with peace of mind outdoors.
(2) Good plasticity: it can be easily processed into special products, such as glass, partitions, bathtubs.
(3) Good transparency: It is a colorless transparent plexiglass sheet, which is a very transparent material with a light transmittance of over 92%. Often used to cut off, giving people a hazy visual beauty.
2.The disadvantages of acrylic board
Although the acrylic board is very good, there are also shortcomings. Generally, ordinary acrylic boards have low hardness, poor heat resistance, and low elongation, so they are easily cracked, brittle, deformable, and unstable in color. Fluffing easily occurs during use. The formed bathtub generally has a large stretch at the bottom, which is prone to color changes. Usually, the corners of the bottom can be seen with whitening, yellowing, and other discoloration.
Each kind of board has its advantages and disadvantages. The same is true for acrylic boards. When you choose acrylic boards, you can learn more about the content described above. I hope the above information can help you better understand the acrylic boards.
Advantages of endurance board:
(1) Light transmittance: The light transmittance of the endurance plate can reach 89%, which can be as beautiful as glass. UV-coated panels will not produce yellowing, fogging, and poor light transmission when exposed to sunlight. Ten years later, the loss of light transmission is only 10%, and the loss rate of PVC is as high as 15% -20%. The glass fiber is 12 % -20%.
(2) Impact resistance: The impact strength is 250-300 times that of ordinary glass, 30 times that of acrylic plates of the same thickness, and 2-20 times that of tempered glass. There are no cracks when falling two meters below a 3kg hammer. "Glass" and "sound steel".
(3) Anti-ultraviolet: One side of the PC board is co-extruded with an anti-ultraviolet (UV) coating, and the other side has anti-condensation treatment, which combines anti-ultraviolet, heat insulation and anti-fog functions. It can block ultraviolet rays from passing through, and is suitable for protecting valuable artworks and exhibits from being damaged by ultraviolet rays.
(4) Light weight: The specific gravity is only half that of glass, which saves the cost of transportation, removal, installation and support of the frame.
(5) Flame retardant: The national standard GB50222-95 confirms that the endurance board is a flame retardant grade I, namely B1 grade. The PC board's own ignition point is 580 ° C, and it will self-extinguish after leaving the fire. It will not generate toxic gases during combustion and will not promote the spread of fire.
(6) Bendability: According to the design drawing, it can be cold-formed at the construction site and installed into an arched, semi-circular roof and window. The bending radius is 175 times of the thickness of the plate, and it can also be heated.
