20mm Clear Perspex® Sheet Details
20mm Clear Cast Acrylic’s uses are almost impossible to count, thanks to its excellent properties. 20mm Cast Perspex® panels are strong, durable, yet easy to handle and fabricate. Clear acrylic material greatly outperforms glass but weighs only half as much, making it the first choice for glass replacements.
The chemical name for acrylic is Poly(methyl methacrylate), or PMMA. Some of the popular brands supplying PMMA sheets are Lucite®, Plexiglas®, and Perspex®.

Customer Reviews
Average ratings from our customers:
- Very useful bespoke serviceI have some very old plastic path lights which I installed 40 yr ago. The clear plastic lantern part of the lights has become very brittle over the years and I have to replace them on occasion. Recently the base of one of the lanterns broke so I needed a disc with a central hole. I was able to order a bespoke replacement which has worked perfectly.
