Perspex (PMMA) is not a soft solid.
No, it's plastic
yes
Yes it is in fact, Pespex is a thermoplastic because although it is not flexibilre it melts when it comes in contact with heat so they classify it as a thermoplatic Hope this helps :)
Poly(methyl methacrylate) (PMMA) or poly(methyl 2-methylpropenoate) is a thermoplastic and transparent plastic. Chemically, it is the synthetic polymer of methyl methacrylate. It is sold by the tradenames Plexiglas, Limacryl, R-Cast, Perspex, Plazcryl, Acrylex, Acrylite, Acrylplast, Altuglas, Polycast, Oroglass and Lucite and is commonly called acrylic glass or simply acrylic. Acrylic, or acrylic fiber, can also refer to polymers or copolymers containing polyacrylonitrile. The material was developed in 1928 in various laboratories and was brought to market in 1933 by Rohm and Haas Company. PMMA is often used as an alternative to glass, and in competition with polycarbonate (PC). It is often preferred because of its moderate properties, easy handling and processing, and low cost, but behaves in a brittle manner when loaded, especially under an impact force. To produce 1 kg of PMMA, about 2 kg of petroleum is needed. In the presence of oxygen
perspex is a plastic
Perspex Island was created in 1991.
john harry smith invented perspex
Perspex is cheaper. 100%. Defo. IRL.
Perspex (PMMA) is not a soft solid.
E=2800 MPa nu=0.38 For Perspex sheet
No, Perspex is a form of man made plastic.
no.
The Critical angle of perspex is 42o.It is the same as the critical angle of glass.
No Perspex is NOT an element. It is a polymer called methyl methylacrylate. It is manufactured industrially and sold in the US under such names as Perspex, Plexiglas and Lucite
No
its stronger
