Detailed description:

Light transmission

Acrylic cast sheet has a light transmission of 37%. The opal acrylic diffracts and diffuses light evenly making it the perfect choice for illuminated signage.

Hard wearing

Cast acrylic is one of the hardest thermoplastic sheet materials available and its attractive aesthetics remain for longer than other plastic sheet materials.

Light weight

Opal cast acrylic weighs half as much as an equivalent glass panel making fabrication, installation and transportation a far more attractive proposition.

High gloss finish and easy to clean

Its high gloss finish is not only very attractive but also more practically very easy to clean.

Weather resistant

With excellent resistance to the elements, cast acrylic performs well outside. No significant changes in appearance are expected over 10 years.

Manufacturing process 

Cast acrylic is manufactured by pouring monomer between two sheets of high quality glass and polymerised in batches in a carefully controlled manufacturing process.

Recyclable

Opal cast acrylic can be recycled all the way back to its original raw material, the monomer.

What are polished edges?

When we cut an acrylic sheet to size, the saw blade produces a matte finish on the edges of the panel. We use a technique called diamond polsihing to polish the edges to a bright, smooth and glossy finish. 

Our diamond edge-polishing machine polishes the edge of acrylic by running a rotating, diamond tipped wheel along the edge of the material.

How do I clean acrylic?

  1. Blow or lightly brush away any dust and loose dirt from the surface of the acrylic
  2. Using a mild solution of lukewarm water and washing up liquid clean the surface of more resistant dirt and grime.
  3. Rinse with clean water.
  4. Blot dry with a microfibre cloth to prevent water spotting.

I used a 420x297mm sheet of opal cast acrylic for making my own light box. The actual cut on the acrylic sheet was 100% accurate on the measurements I ordered. Works great for diffusing the light evenly as it says on the description of this item! Very pleased with it! Thank you @SimplyPlastics

Used a piece of Opal 10mm acrylic from Simply Plastics as a loft hatch. The roof space in our bungalow is flooded with light and now we've let some of the light into a dark internal corridor. Works a treat.
