What is the difference between PMMA and PC board?

The basic raw materials of PC board and acrylic board are different. Acrylic is polymerized by "methyl methacrylate monomer MMA. Or it is extruded from acrylic pellets through an extruder. PC board is made of polycarbonate as the main component, using co-extrusion technology CO- EXTRUSION.

Acrylic is relatively brittle, and its resistance to impact is not as good as that of an endurance board. It will break if you hit the acrylic with a hammer, but the endurance board will not. The surface light transmittance, the new material endurance board has a high light transmittance and looks very transparent, and the 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, which can be seen by the naked eye.

Advantages and disadvantages of acrylic board:

1. The advantages of acrylic sheet

(1) Excellent weather resistance: Acrylic board has very good adaptability; it has strong adaptability to natural environment. Even if it is exposed to sunlight, wind and rain for a long time, it will not change its performance; it has good anti-aging performance; it can be used safely outdoors.

(2) Good plasticity: It can be easily processed into special products, such as glass, partitions, and bathtubs.

(3) Good transparency: It is a colorless transparent plexiglass sheet, a material with excellent transparency, with a light transmittance of more than 92%. It is often used for partitions, giving people a vague and vague visual beauty.

2. Disadvantages of acrylic board

Although the acrylic sheet is excellent, there are still some shortcomings. Ordinary acrylic sheets are easy to crack, break, deform, and have unstable colors due to their low hardness, poor heat resistance, and low elongation. It is prone to fluffing during use. The molded bathtub is generally prone to color changes due to the large stretch of the bottom, and it is usually seen that the corners of the bottom have whitening, yellowing and other discoloration.

Each kind of sheet has its advantages and disadvantages. The same is true for acrylic sheet. When choosing acrylic sheet, you can learn more about the content mentioned above. I hope that the above information can help you understand acrylic sheet better.

PC board advantages:

(1) Light transmittance: The light transmittance of the endurance board can reach 89%, which is as beautiful as glass. UV-coated panels will not produce yellowing, atomization, or poor light transmission when exposed to sunlight. After ten years, the loss of light transmission is only 10%, the loss rate of PVC is as high as 15%-20%, and 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 is no crack when it falls two meters under a 3kg hammer. The reputation of "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 an anti-condensation treatment, which integrates anti-ultraviolet, heat insulation and anti-fogging functions. It can block ultraviolet rays from passing through, and is suitable for protecting valuable artworks and exhibits from ultraviolet rays.

(4) Light weight: the specific gravity is only half of that of glass, saving the cost of transportation, handling, installation and supporting frame.

(5) Flame retardant: The national standard GB50222-95 confirms that the endurance board is flame-retardant grade 1, namely B1 grade. The ignition point of the PC board is 580℃, and it will self-extinguish after leaving the fire. It will not produce toxic gas during combustion and will not promote the spread of the fire.

(6) Flexibility: According to the design drawing, cold bending can be used on the construction site to install into an arch, semi-circular roof and window. The bending radius is 175 times the thickness of the adopted plate, and it can also be bent.
