PMMA's mechanicalstrength is high: PMMA has a molecular weight of about 2 million,is a long chain of macromolecule, and the chain forming themolecules is very soft, so the strength of PMMA is relatively high,the tensile and impact resistance of glass is 7 ~ 18 times higherthan that of ordinary glass. There is a type of polymethylmethacrylate that has been heated and stretched, in which themolecular segments are arranged in a very orderly manner, resultingin a significant increase in the toughness of the material. A nailis driven into the PLEXIGLASS, and even if the nail penetrates, nocracks are produced on the plexiglass. The perspex also does notbreak into pieces when it is broken. Therefore, stretch treatedplexiglass can be used as a Bulletproof glass and also as a canopyon aircraft.
