Acrylic material itself is formaldehyde-free. Acrylic, also known as PMMA or plexiglass, is chemically called polymethyl methacrylate. Acrylic is an important plastic polymer material with early development, which has good transparency, chemical stability and weather resistance, easy dyeing, easy processing and beautiful appearance, and is widely used in the construction industry.
Acrylic products include acrylic board, acrylic plastic particles, acrylic light boxes, signboards, acrylic bathtubs, acrylic artificial marble, acrylic resin, acrylic (latex) paint, acrylic adhesive and other products, and there are many kinds.
How to choose acrylic board
1, transmittance
It can be distinguished from the transmittance, and the method is very simple. Let acrylic shine in the sun and see how transparent it is. High-end plates are transparent and pure, so you don't have to worry about yellowing or bluing. If the inferior plate has poor light transmittance, it is easy to yellow.
2. Thickness
See if the thickness is consistent with the measured thickness. High-quality acrylic board is scratch-resistant and will not produce irritating smell when cut. The thickness of inferior plate is not up to standard, the surface is easy to scratch, and it will also produce irritating taste.
3. Fire
When choosing, you can test it with fire. If the combustion does not produce bubbles, deformation and odor, it means that it is a good plate. If it is deformed after heating and bubbles are generated, it is not recommended to buy it.
