The most common name used to describe clear plastic would appear to be Perspex, and there are many others, but they are all actually trade names for Acrylic or PMMA (Polymethylmethacrylate).
Acrylic is used in a huge range of products across a wide range of industries from low-tech to high and from low-cost to high budget.
It can be moulded, machined, fabricated and is widely available off the shelf as sheet, rod, bar, tube etc. Bray Plastics have extensive experience working with and producing acrylic products for their customers.
One recent example was a vacuum door produced for Leskers UK Ltd that was fitted to a high end vacuum chamber, as illustrated in the image below. The door was machined from 80 mm acrylic and finished by hand.
