Acrylic sheet thermal properties.

Relative density 1 19 g cm3 rockwell hardness m 102 water absorption 2 flammability class 3 bs 476 pt 7 ul94 hb. It is pro duced by an innovative process resulting in a sheet offering the easy handling and processing of extruded sheet along with the high optical characteristics and low stress levels expected of cast products. Acrylic sheet is easy to fabricate bonds well with adhesives and solvents and is easy to thermoform. Acrylic sheet exhibits glass like qualities clarity brilliance and transparency but at half the weight and many times the impact resistance of glass.

To replicate the insulating properties of glass the acrylic sheet has to be. 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.

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. For chemically resistant plastic view our chemical resistance of plastics chart. General information and physical properties plexiglas 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. Polycarbonate and acrylic share many of the same types of plastic sheeting options like clear colored mirrored and more.

Use our interactive properties table below to explore by property group sort or compare two or more plastic materials. The higher the lambda value the more heat the material conducts and therefore the less it insulates.

While the form may be the same you will find that a clear polycarbonate sheet and a clear acrylic sheet are vastly different due to the physical and chemical properties of the plastic.

It has superior weathering properties compared to many other transparent plastics.
