Features of PMMA

Polymethyl methacrylate is called PMMA. The chemical name of the polymer transparent material is polymethyl methacrylate, which is a polymer compound obtained by polymerizing methyl methacrylate. It is an important thermoplastic that was developed earlier. Plexiglass is divided into colorless and transparent, colored and transparent, pearlescent and embossed plexiglass. Plexiglass is commonly known as Acrylic, Zhongxuan Acrylic, and Acrylic. Plexiglass has good transparency, chemical stability, mechanical properties and weather resistance, easy dyeing, easy processing, and beautiful appearance. Plexiglass is also called gelatin glass, acrylic and so on.

Raw material of PMMA is colorless and transparent, and its light transmittance is 90%---92%. It has strong toughness and is 10 times larger than silicon glass.

Excellent optical, insulating, processability and weather resistance.

It is dissolved in organic solvents such as carbon tetrachloride, benzene, toluene dichloroethane, chloroform and acetone.

It has high transparency and brightness, good heat resistance, and is tough, hard and rigid. The heat distortion temperature is 80 °C and the bending strength is 110Mpa.

Due to these features, it is popular in skincare and cosmetic packaging, like acrylic bottles and jars. But as it will be dissolved in organic solvents, PMMA containers cannot touch skincare or cosmetic product, such as face cream, lotion and foundation. That is why PMMA pacakaging are double walls.
