The mechanical properties of acrylic are as follows.
Acrylic sheet yield strength.
Extruded acrylic costs less than cast and is more dimensionally stable meaning the thickness is more consistent across sheets.
Poly methyl methacrylate pmma also known as acrylic acrylic glass or plexiglass as well as by the trade names crylux plexiglas acrylite astariglas lucite perclax and perspex among several others see below is a transparent thermoplastic often used in sheet form as a lightweight or shatter resistant alternative to glass the same material can be used as a casting resin or in inks.
9 000 psi impact strength 4ft lbs in rockwell.
Use our interactive properties table below to explore by property group sort or compare two or more plastic materials.
Acrylic is a transparent thermoplastic homopolymer known more commonly by the trade name plexiglass the material is similar to polycarbonate in that it is suitable for use as an impact resistant alternative to glass particularly when the high impact strength of pc is not required.
4 2 modulus of elasticity.
Polycarbonate is strongest followed by petg pet impact modified acrylic sheet then general purpose acrylic sheet.
For chemically resistant plastic view our chemical resistance of plastics chart.
Localized concentrated stresses must be avoided.
400 000 psi flexural strength.
It was first produced in 1928 and was brought to market.
475 000 psi compressive strength.
How does acrylic compare to other plastics in strength.
Extruded acrylic extruded acrylic sheet can be manufactured to any length which often results in cost savings since yield loss can be minimized when parts are cut from custom sheet sizes.
What are the benefits of acrylic over glass.
18 000 psi modulus of elasticity.
Prior to the yield strength the material will act elastically meaning that if the strain were halted at any point in the elastic portion the material would return to its original length.
10 000 psi elongation rupture.
Although the tensile strength of cell cast is 10 000 psi 69 m pa at room temperature astm d638 stress crazing can be caused by continuous loads below this value.
Acrylic sheet 1 plexiglas t combines the beauty of plexiglas mc with additional toughness gained from the use of our advanced impact acrylic chemistry this union produces the aesthetics desired with increased toughness plexiglas t is more than 50 tougher than standard acrylic sheet.
For most applications continuously imposed design loads should not exceed 1 500 psi 10 4 m pa.
Yield strength the yield strength of the plastic is the where the material begins to deform in a plastic fashion.
Extruded acrylic is also the easiest grade to thermoform and the easiest to bond using solvent cements.
It is available in colorless white and black in thick.
430 000 psi shear strength.
Softer with a lower melting temperature than in its cast form extruded acrylic is easier to laser cut rout and polishes more cost effectively.
16 500 psi modulus of elasticity.
