What is it? Acrylic is a useful and versatile plastic, which can be clear, tinted or coloured. It resembles glass, but its acrylic properties make it superior to glass in many ways, such as strength and safety. The technical name is Poly(methyl methacrylate) (PMMA), and it comes in Extruded or Cast forms. Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. There are two types: sheet or solid and Twin/Multiwall. PETG is a clear plastic material that is easy to mould. It is also called Polyethylene terephthalate or Poly.
What are its main features?
The main acrylic properties are:
  • Stronger and lighter than glass
  • More impact resistant than glass
  • Better insulator an UV rating than glass
  • It is easy to cut and form to different shapes and sizes
Polycarbonate properties include:
  • Much stronger than Acrylic and PETG
  • Transparent to visible light
  • Can be formed and cut to shapes easily
  • Impact resistant and does not crack or shatter like glass/acrylic
  • Good fire rating self extinguishing
PETG properties include:
  • Very easy to mould and shape
  • Much stronger than acrylic or glass
  • Good impact resistance
  • Weather resistant
  • High light transmission
What is it commonly used for There are a number of acrylic uses, including: shed windows, kitchen and bathroom splashbacks, secondary glazing, shower screens, signs and signage, trophies and awards, decorations and jewellery.

Common polycarbonate uses differ for solid and multiwall polycarbonate:

Sheet/Solid is used as a glass substitute where strength is important.

Multiwall is used most commonly in roofing for Conservatories, lean-tos, greenhouses etc.

PETG uses include glazing, bike/bus shelters, protective shields and vending machines among others.
What are the common brands? Common acrylic brands include Plexiglas, Acrylite, Lucite, and Perspex among several others. Common polycarbonate brands include Lexan, Marlon, Makrolon, Palsun and many more. PETG brands include Dacron and Terylene.
What sort of sizes and colours Sizes are available There are hundreds of colours and finishes available in several thicknesses. Polycarbonate is generally clear but also comes tinted and in white, opal and black. Sizes range from 2mm to over 30mm for multiwall. PETG is a very thin material, generally between 0.5mm and 6mm in thickness.
Price Point The price of acrylic is cheaper than Polycarbonate and PETG. The price of polycarbonate is generally more than both PETG and Acrylic. The price of PETG is in between Acrylic and Polycarbonate.

In addition we also sell the following types of plastic:

- Polypropylene

- Foam PVC

Polypropylene is a tough, durable and impact resistant protection board, available in a range of different options to suit specific project requirements. Lightweight and durable, it has a good Impact resistance. It is Waterproof and Resistant to chemicals as well as being Flexible with a High impact resistance. It can be easily cut/bent/scored and is suitable for printing onto its surface.

Polypropylene is often used by estate agents for signs and notices, but is also used for protection and insulation in a variety of applications. Find out more about Polypropylene sheeting.

Foam PVC

PVC foam sheet is a lightweight material with good mechanical and insulation properties. A mixture of Polyvinyl chloride and polyurea, foam PVC has a good bond strength and takes a solid shape due to its linear, closed-cell foam structure.

Suitable for indoor and outdoor use, foam PVC has low impact strength and due to its range of colours it is often used for signage and displays. It is also suitable for printing directly on to the material with the right equipment.
