Acrylic has high mechanical strength

The relative molecular weight of acrylic is about 2 million. It is a long-chain polymer compound, and the chain forming the molecule is very soft. Therefore, the strength of PMMA is relatively high, and its tensile and impact resistance is 7-18 times higher than that of ordinary glass. There is a kind of PMMA that has been heated and stretched, in which the molecular segments are arranged in a very orderly order, so that the toughness of the material is significantly improved. Even if the nail penetrates into the plexiglass, there will be no crack on the plexiglass. This kind of plexiglass will not break into pieces after being punctured by a bullet. Therefore, the stretched plexiglass can be used as bulletproof glass and cockpit cover of military aircraft, and the acrylic display stand is not easy to be damaged when bumped in stores.

Acrylic is easy to process

Acrylic can not only use lathe to cut and drill holes, but also use acetone, chloroform and other tools to bond into various shapes. It can also use blow molding, injection, extrusion and other plastic molding methods to process products as large as aircraft cockpit cover, as small as dentures and dentures. Designers can design freely, and acrylic can basically process them, which is very important There are a lot of driving forces for creative appearance design.

Acrylic highly transparent

Acrylic is the most excellent transparent polymer material at present, with a light transmittance of 92%, which is higher than that of glass. The tube of a solar lamp called an artificial small sun is made of quartz, because quartz can completely pass through ultraviolet rays. Ordinary glass can only pass through 0.6% UV, but plexiglass can pass through 73%. In shopping malls, the use of acrylic display frame, through the light transmission, can render a colorful visual effect.

Acrylic is light in weight

The density of acrylic is 1.18kg/dm3. The weight of the same material is only half of that of ordinary glass, and 43% of that of aluminum (a light metal). Even if acrylic display stand is used outdoors, it is easy to move.
