Pmma Plastic Sheets

The highest quality pmma sheets are produced by cell casting but in this case the polymerization and molding steps occur concurrently.

Pmma plastic sheets.

Polymethylmethacrylate pmma is a thermoplastic polymer also known as acrylic or acrylic glass is a transparent and rigid thermoplastic often used in sheet form as a lightweight or shatter resistant alternative to glass. Acrylic glass or pmma is the most environmentally sound plastic alternative consistent with a sustainable development and circular economy approach. It can be colored molded cut drilled and formed. What is acrylic pmma and what is it used for.

The same material can be used as a casting resin or in inks and coatings among many other uses. Polymethyl methacrylate acrylic pmma is a tough highly transparent material with excellent resistance to ultraviolet radiation and weathering. Poly methyl methacrylate pmma also known as acrylic or acrylic glass as well as by the trade names crylux plexiglas acrylic 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. It is a clear colorless polymer available in pellet small granules and sheet forms which are then formed with all thermoplastic methods including injection molding compression molding and extrusion.

Once the first sheets have been produced they can be recycled indefinitely through a scrapping process. Its higher impact strength makes it a great glass replacement for applications such as garage door windows storm windows and other glazing needs. Optix acrylic sheet is a lightweight impact resistant optix acrylic sheet is a lightweight impact resistant transparent material that is a great replacement for glass in many applications. This chamber is heated which combined with the shear from the screw s melts the plastic and conveys it through a die at the end of the extruder.

Extrusion is the second widely used processing technology for pmma resin. It has superior weathering properties compared to many other transparent plastics. It is commonly called acrylic glass. The acrylic glass sheets are crushed then heated before being re melted into a liquid syrup.

Acrylic is an economical alternative to polycarbonate pc when extreme strength is not necessary. Acrylic sheet exhibits glass like qualities clarity brilliance and transparency but at half the weight and many times the impact resistance of glass. In this process the resin pellets are melted and conveyed in a heated barrel containing one or two rotating screws.
