Introduction to Acrylic Materials

PMMA is also called acrylic or sub-force. Are English Chinese acrylic name, the chemical name for the polymethyl methacrylate. With high transparency, low price, easy machining, etc., is often used glass replacement materials. Stability, mechanical properties and weather resistance, easy to dye, easy processing, the appearance of beautiful and so on. Plexiglass products can usually be divided into cast, extruded and molded.

characteristic:

1. Density: PMMA density is lower than glass, its density is about 1150-1190kg / m3, is glass (2400-2800kg / m3) half;

2. High mechanical strength

3. Higher light transmittance

Visible light: PMMA is the most excellent polymer transparent material, the transparency rate can reach 92% higher than the glass transmittance

UV: quartz can be completely through the UV, but the price is high, ordinary glass can only pass 0.6% UV, but PMMA is able to pass 73%. On the other hand, PMMA has better stability than polycarbonate in the case of irradiation with ultraviolet light.

Infrared: PMMA allows less than 2800nm wavelength through the infrared. Longer wavelengths of IR, less than 25,000 nm, can be largely blocked. There is a special colored PMMA that allows a specific wavelength IR to pass while blocking visible light.

4. Chemical resistance: acid, alkali, salt has a strong decay resistance, but easy to melt in organic solvents.

5. Processing performance: easy processing, can be bonded, curium, planing, carving, grinding, screen printing, sandblasting and other manual and mechanical processing, heating can be bent into a variety of acrylic products.

6. Heat resistance is not high Acrylic commonly known as plexiglass, tough, the case of chemicals is not easy to respond, chemical stability, for cosmetics is suitable.

The benefits are as follows:

1, with a crystal-like transparency, light transmission rate of 92% or more, soft light, clear vision, with the dye color of acrylic and have a good color effect.

2, the acrylic plate has excellent weather resistance, high surface hardness and surface gloss, and better high temperature performance.

3, the acrylic board has a good processing performance.
