White Plexiglass Acrylic #7328

Shop our wide range of white cast plexiglass #7328 pre-cut stock sheets of 1/8" to 1/2" thick. We also stock 1/16" thick extruded pre-cut sizes. Select the thickness you need below to find the sheet or sheets for your next project. Both the cast and extruded sheets come with a paper masking.

White Plexiglass Acrylic #7328 is designed to allow a certain percentage of light to pass through, which makes it ideal for light diffusing applications, such as backlit signs. If is not as white or opaque as white #3015, but #7328 white is translucent just enough to allow some light to pass through, brightening up the sheet. Its light-diffusing properties help to evenly distribute light making it an excellent choice for illuminated signs, both indoors and outdoors. Like other acrylics, it is durable, resistant to impact, and shatter resistance.

White #7328 has a glossy finish on both sides.

Applications: signage, backlit or illuminated signs, retail displays, furniture, shelving, display cases, point-of-purchase displays, exhibit displays, decorative elements, backsplashes, sneeze guards, bathroom elements, dividers, partitions, art installations, DIY projects, and a variety of other applications.

Available in various thicknesses and sizes, our acrylic plexiglass sheets are suitable for a myriad of applications. We understand that every project is unique, which is why we offer several pre-cut stock sizes and custom cut-to-size and cnc services to meet your specific needs. We also offer three different grades of white plexiglass with a glossy finish on both sides (see our White P95 for sheets with a matte 1 side/glossy 1 side finish):

  • White #7328 - a solid sheet, but will allow some light through (translucent). It is an excellent choice for applications that need to be back lit, such as back lighted signs or displays. (approx. light transmission*: 9.1%)

  • White #3015 - classified as an opaque solid plexiglass sheet. Opaque sheets transmit a negligible amount of light to no light at all. (approx. light transmission*: 0.2%)

  • White #2447 - will also allow some light through (more than white #7328). White #2447 has a slight milky white look to it and is often used for applications that need to be back lit, but which need more light to transmit through the material. For example: photo light tables, lighted drawing tables, x-ray chart readers, overhead lights, skylights. (approx. light transmission*: 45.2%)
