Features
ACRYLIC is a popular material among designers and hobbyists.
ACRYLIC offers many important features including:
Clarity (light transmission for clear sheet is 92%).
Light weight.
Strength
Workability
Being a thermoplastic, ACRYLIC is rigid under normal temperatures but softens when brought up to a sufficiently high temperature.
Product Availability 
ACRYLIC is available in a wide range of thickness and sheet sizes. 
The product is also available cut-to-size. 
Thickness: 2mm -25mm

Sheet Sizes:
2440x1220
2490x1270
2490x1880
3050x2030

The following gives a basic outline on the properties and fabrication techniques used for ACRYLIC. PSP recommends that for thermoforming and complex fabrication projects you consult a professional plastic fabricator.
Technical
Manufactured from: Methyl Methacrylate Monomer

Working Temperature: -40C- 80C
Forming Temperature: 140C- 180C
Light Transmittance: Clear 92%
General
During most phases of fabrication or installation, it is recommended to keep the polythene or paper masking in place. You can remove the masking by rolling it round a circular object (e.g. a cardboard tube). During cutting and drilling always wear your safety glasses and make sure the ACRYLIC is well supported.
Cutting
Scoring: ACRYLIC sheet up to 4.5mm can be cut by this method. Heavily score the sheet and press in a straight line on either side of the groove produced.
Cutting with power saws: When cutting with a hand held circular saw, clamp the sheet securely to minimise vibration. Be sure the saw is up to full speed before beginning the cut. The blade should be fine toothed, preferably carbide tipped. Cutting with jigsaws: Make sure the jigsaw is set at high cutting speed. Do not allow the sheet to overhang as the vibration may crack the sheet. Always switch the jigsaw on before starting the cut. Again the blade should be fine toothed.
Drilling
Any kind of hand or power drill may be used for drilling ACRYLIC. A $tationary drill press is preferred as it gives better control and accuracy. The drill bit should be carbide tipped and blunted (this stops "corkscrewing"). Drill at a good speed, with not too much pressure. Withdraw the drill frequently to eject debris and to minimise heating the material.
Polishing
Before polishing the edges of ACRYLIC it should be sanded to a smooth, sanitary finish. A finer grit will produce a smoother finish
use a soft cloth and "Brasso". For larger jobs, you can use a buffing wheel and a non-silicone car polish. Never polish cement joints.
Forming
ACRYLIC sheet, being thermoplastic, softens when heated and hardens when cooled. The forming and heat bending of ACRYLIC can be a difficult process. There are numerous plastic fabricators throughout the country who are well versed in the different forming techniques available (see your glass merchants for details).
Cold Bending
The minimum radius is approximately 200 times the thickness of the sheet eg 3mm -600mm radius, 4mm -800mm radius etc. Curving of ACRYLIC can cause stress on the sheet unless a large radius is used. Please check with your glass merchant.For permanent glazing such as barrel vaults, PSP recommends using a high quality guaranteed sheet. Also for -the majority of boat windscreens PSP recommend a high quality ACRYLIC. For forming of windscreens we would recommend thermoforming by an established plastic fabricator.
Cementing
Your local glass merchant will have ACRYLIC cement available in tubes. All surfaces to be cemented should fit together accurately. Flat straight edges are easier to work with.
Simply apply the glue to the edges, hold the parts together briefly and then fix them in a jig and apply pressure.
Fixing
If screwing, allow for oversized holes to accommodate expansion and contraction. SUNTUF screws are available from your glass merchant. Do not use counter sunk screws.
Cleaning
ACRYLIC can be c!eaned with a soft cloth or sponge, using soap or mild detergent.
Guarantee
Standard ACRYLIC sheets do not have a guarantee. However, GLAZING ACRYLIC sheets carry a limited guarantee up to ten years (see your glass merchant for details
