Three properties of acrylic sheet plexiglass material

Acrylic sheet is also called plexiglass. This material has many special characteristics because these characteristics are widely used. In daily life, many people feel the conscience service of acrylic board and like to apply it to their own homes. Acrylic sheet is light yellow at high temperature, the resistance to silver particles decreases obviously, the impact strength is slightly improved, and other physical properties are almost unchanged. The following introduces the three properties of acrylic sheet plexiglass materials.
1. Good mechanical properties
The mechanical properties of acrylic sheet have good comprehensive mechanical properties. In the forefront of general plastics, the tensile, bending, and compressive strengths are all higher than polyolefin, but also higher than polystyrene, polyvinyl chloride, etc., and the impact toughness is poor. But it also has higher mechanical properties such as stretching, bending, and compression than casting bulk polymerized polymethyl methacrylate sheets (such as for aviation plexiglass panels), and can reach the level of engineering plastics such as polyamide and polycarbonate.
2. Heat resistance
Acrylic boards can be copolymerized with monomers and acrylic acid esters or diester glycol esters to improve heat resistance. The mechanical properties of acrylic sheet are basically that hard and brittle plastics have notch sensitivity and are easy to crack under stress, but the fracture is not as sharp and uneven as ordinary inorganic glass, which improves the toughness and ductility of the material.
3. Chemical and solvent resistance
Acrylic sheet can withstand thin inorganic acid, but strong inorganic acid can make it corrode and alkali resistant, but warm sodium hydroxide and potassium hydroxide can make it etch, make it etch, and make it etch-resistant. Salt and oil, resistant to fatty hydrocarbons, insoluble in water, methanol, glycerin, etc., but can absorb alcohol swelling, it can be dissolved in many chlorofluorocarbons and aromatic hydrocarbons, such as two kinds of ethane, trichloroethylene, chloroform, toluene Etc., vinyl acetate and acetone can also dissolve it.
All in all, the three major properties of acrylic sheet plexiglass materials are good mechanical properties, heat resistance, chemical resistance and solvent resistance. No matter how you choose the acrylic sheet, you need to understand that the acrylic sheet has good flame retardancy and weather resistance. The acrylic sheet has excellent atmospheric aging resistance. Its samples have undergone many years of natural aging tests, weight changes, tensile strength, and light transmittance. Decline is also normal.
