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.


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

I used this as a new top for my bedside tables! The tops were damaged and stained from cups of tea and this was a great way to have a new clean and wipeable surface. Reuse and upcycle!

Perfect for job and finish required

The acrylic sheeting I purchased was used for the top of my side tables , and very effective it looks too. Very happy with this purchase .

This product was purchase as a prototype for laser cutting and engraving flight panels for a B737 simulator. So far the finish has exceeded my expectations and i will be purchasing more in the future.

They were used to cover my wooden doorway room deviders the wood was painted white but soon became scruffy so glued the acrylic sheets on now able to wipe clean perfect

Use two panels to protect my kitchen walls from dirt from a shaking dog! Works a treat and I don’t take the paint off the wall when wiping it away anymore!!

This was for a diffuser for a small light box so I can scan 6x6 negs and transparencies. It was cut accurately and does the job perfectly. Thank you.

Just what we needed to cover top of shelf unit.

Used the product to lay on top of shelf unit. Great quality and easy to clean, very discrete so looks part of the unit. fantastic service.

Bought this for bathroom shelves and to give protection to mosaic tile shelf. works so good, I hardly notice it is there. Price was good, delivery was timely and efficient and it is a local company.

As always a quality product and service from Simply Plastics, always able to help and packaged to absolute protection.

Protection for bathroom shelves and window sills. I have also ordered replacement "glass" for pictures.

used for lift car lighting diffuser. easy to trim and fit. gave good overall lighting without shadows. very good product.

I made a cinema sign which doubled up as a light box. The acrylic was perfect. Came in great condition and really fast delivery.

Good quality, Good delivery and Exact to size

I used the product to make a custom sized light box to display a batik painting. The size was cut perfectly to the size I required, was very well packaged, arrived on time and the finish was flawless. Thank you. I’m very happy and will be buying from you again

Diffusing a light sheet to illuminate logo plate

I am using the 800 x 800, 5 mm thick, translucent white for a piece of art work. It’s working perfectly so far, a way to go yet, gluing a mosaic portrait on it and adding lights behind it. So far, so good.

Would highly recommend this opal sheeting l ordered 2 sheets cut to size with polished edges 1696 x 525 mm to replace the polycarbonate for my kitchen lights ,l am well please lets the light through great

Quality was excellent, price was competitive with other online retailers, packaging was secure and delivery was within the estimated window. The 3mm opal acrylic is used to create even backlighting by dissipating led strip lighting for some negatives in a frame.

Purchased a cut to size 3mm piece of opal acrylic for an edge lit mirror project which was perfect!

Bought a sheet of opal acrylic to use up high in an internal partition wall to give diffused light into a shower room without losing privacy. It's worked really well so money well spent and a very cost effective solution.

I used this product for a lightbox panel. An excellent product and an excellent and speedy service too. Highly recommended.

Good quality - we used this for some old recessed strip light covers in a ceiling and they work well. great service and quick delivery.

Used for a signal light. Very useful to be able to have it cut to exact size. Made a nice finished job. Very pleased.

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

Bespoke oak sliding doors to mimic Japanese paper doors. Guys got it to me quickly, and was very helpful, I will definitely use these guys again.

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.

Used the product in an exhibition stand, excellent price, well wrapped for courier delivery, branded material which I was not expecting for the cost.

Used the product for a home made sign board, good quality material, good service, would recommend!

Good quality opal sheet. Received next day as expected.
