Acrylic sheet Physical properties

The density of PMMA is lower than that of glass: PMMA has a density of approximately 1.15-1.19 g / cm³, which is half of glass (2.40-2.80 g / cm³) and 43% of metallic aluminum (belonging to light metals).

The mechanical strength of PMMA is high: the relative molecular mass of PMMA is about 2 million, it is a long-chain polymer, and the molecular chain forming it is very soft. Therefore, the strength of PMMA is relatively high, and it has the ability to resist stretching and impact. 7 to 18 times higher than ordinary glass. There is a kind of organic glass that has been heated and stretched. The molecular segments are arranged in an orderly manner, which significantly improves the toughness of the material. When nailed into this plexiglass, even if the nail penetrates, there is no crack. This kind of plexiglass will not break into fragments after being penetrated by bullets. Therefore, the stretched PMMA can be used as bullet-proof glass and also as a cockpit cover on military aircraft.

PMMA has a lower melting point: PMMA has a melting point of about 130–140 ° C (265–285 ° F), which is much lower than the high temperature of about 1000 degrees glass.

PMMA has high light transmittance

Visible light: PMMA is currently the most excellent polymer transparent material, with a light transmittance of 92%, which is higher than that of glass [1].

Ultraviolet light: Quartz can completely filter ultraviolet light, but the price is high, ordinary glass will only allow 0.6% of ultraviolet light to pass through. PMMA can effectively filter ultraviolet rays with a wavelength less than 300nm, but the filtering effect between 300nm and 400nm is poor. Some manufacturers [2] coat the PMMA surface to increase its effectiveness and properties in filtering out UV light from 300nm to 400nm. On the other hand, when irradiated with ultraviolet light, PMMA has better stability than polycarbonate

Infrared: PMMA allows infrared (IR) wavelengths less than 2800nm to pass. Longer-wavelength IR, basically less than 25,000nm, can be blocked. There are special colored PMMAs that can transmit IR at specific wavelengths while blocking visible light (for remote control or thermal sensing, etc.).

The glass transition temperature of PMMA is about 105 ° C.

The refractive index of PMMA is (nd / 25 ° C) 1.49
