Chemical resistancee 30 days of constant exposure with no damage. Colored acrylic sheets are usually cast acrylic while profiles are extruded acrylic. Polyacrylates such as polymethyl methacrylate.
Cast acrylic is usually regarded as a better quality than extruded acrylic. According to their physical properties polymers are divided into three groups as thermosets thermoplastics and elastomersacrylic is a transparent thermoplastic material. Main difference cast vs extruded acrylic.
Cast acrylic tubes offer greater thermal stability greater optical clarity better chemical resistance and superior machining characteristics than extruded acrylic tubes. It has a more constant width than cast acrylic and its better suited to being vacuum shaped bent and heated but it can be more susceptible to cracking in some. Furthermore when hot wire line bending drape or vacuum forming cast acrylic sheets are more malleable pliable than extruded acrylic sheet.
When choosing acrylic sheet for your next project you need to consider which type of acrylic is the most suitable for that particular job cast acrylic or the lower cost alternative extruded acrylic. Plastic may even tolerate chemical for yearsg little or no damage after 30 days of constant exposure to the reagentf some effect after 7 days of constant exposure to the reagent.
