Acrylic Sheet Yield Strength

Yield strength the yield strength of the plastic is the where the material begins to deform in a plastic fashion.

Acrylic sheet yield strength.

For chemically resistant plastic view our chemical resistance of plastics chart. How does acrylic compare to other plastics in strength. 18 000 psi modulus of elasticity. 4 2 modulus of elasticity.

9 000 psi impact strength 4ft lbs in rockwell. What is acrylic pmma and what is it used for. 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. 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.

10 000 psi elongation rupture. Extruded acrylic costs less than cast and is more dimensionally stable meaning the thickness is more consistent across sheets. 16 500 psi modulus of elasticity. 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. Softer with a lower melting temperature than in its cast form extruded acrylic is easier to laser cut rout and polishes more cost effectively. 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. Localized concentrated stresses must be avoided.

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. 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. Use our interactive properties table below to explore by property group sort or compare two or more plastic materials. The mechanical properties of acrylic are as follows.

Polycarbonate is strongest followed by petg pet impact modified acrylic sheet then general purpose acrylic sheet. It was first produced in 1928 and was brought to market. 475 000 psi compressive strength. Extruded acrylic is also the easiest grade to thermoform and the easiest to bond using solvent cements.

Also you may want to use our plastic material selection guide or interactive thermoplastics triangle to assist with the material selection process based on your application requirements. 400 000 psi flexural strength. 430 000 psi shear strength.
