Why Choose Clear Acrylic?
Clear acrylic is a highly versatile thermoplastic that is easy to fabricate, thermoform, and install. It is favoured by architects, retail, sign makers, and DIY enthusiasts for its unique balance of properties.
Key Features & Benefits
- Superior Optical Clarity: With >92% light transmission, clear acrylic allows more light through than standard glass, providing a crystal-clear finish.
- Lightweight & Strong: Acrylic is half the weight of a glass panel of the same size but offers significantly higher impact resistance.
- Weather Resistance: Engineered to perform outdoors, high quality acrylic resists UV aging and weathering. No significant change in appearance should occur for at least 10 years outdoors.
- Easy Fabrication: It is simple to cut, drill, glue, and thermoform.
Common Applications
- Signage: Indoor/outdoor signs and edge-lit LED displays.
- Glazing: Architectural skylights, windows, and balustrading.
- Retail & Display: POS stands, brochure holders, model fabrication, and exhibitions.
- Furniture: Transparent tables, shelving, and protective covers.
Sizes & Customization
Custom Cut to Size
KF Plastics can cut material to any size and quantity. Purchasing cut to size sheets saves you time on fabrication, and lowers your shipping costs by minimizing waste volume.

Need shapes rather than rectangles? We offer laser cutting to your artwork cast acrylic laser cuts with a flame-polished edge straight off the machine.
Tolerances & Specifications
Cutting Tolerance
Cut-to-size panels are supplied to the following tolerances:
- Up to 1000mm: ±0.5mm
- 1000mm to 2000mm: ±1.0mm
- Over 2000mm: ±1.5mm
Acrylic expands and contracts significantly with temperature — approximately 2mm over a
3-metre length across a 10°C change. Allow for movement when designing a fixed installation.
Where a tighter tolerance is critical, note it on your order and we’ll confirm what we can
hold before cutting.
Thickness Tolerance
Cast acrylic is manufactured to a nominal thickness with a tolerance of
±10% (approximately ±0.6mm on a 6mm sheet). This is inherent to the casting
process rather than a defect.
Where consistent thickness is critical — digital printing, precision machining, or press-fit assemblies – we can supply premium cast grades that hold a tighter tolerance:
Protective Masking
All sheets are supplied with protective film on both faces. Leave it on during
fabrication and installation, and remove once the job is complete.
Cut-to-Size Orders
Cut-to-size panels are made to your specification and cannot be returned or
exchanged. Please check your dimensions carefully before ordering. Full sheets in
original condition may be returned under our
returns policy.
Frequently Asked Questions (FAQ)
How do I clean and maintain acrylic sheets?SimonClarke2025-12-03T13:32:39+10:00Clean with a mild soapy warm water solution using a soft cloth or sponge. Never use window cleaners (like Windex) or abrasive scouring pads, as these will damage the surface. For best results, use a specialized plastic polish like our antistatic cleaner. For a complete step-by-step guide and expert tips, please read our full article on How to Clean Acrylic Sheet: A Guide to Maintenance and Care
How does clear acrylic compare to glass?SimonClarke2025-12-03T13:32:48+10:00Acrylic is 50% lighter than glass and has much higher impact resistance. It also offers better optical clarity, transmitting 92% of visible light compared to glass’s 90%.
What is the difference between clear acrylic sheet and Perspex?SimonClarke2025-12-03T13:33:10+10:00There is no actual difference in the material. Perspex® is a brand name for acrylic (polymethyl methacrylate). Whether you call it Acrylic, Perspex, or Plexiglass, you are referring to the same high-quality plastic.
What is the difference between Cast and Extruded Acrylic?SimonClarke2025-12-03T13:33:17+10:00While they look identical, they have different properties. Cast Acrylic is made by pouring liquid into a mould. It is harder, better for machining and laser cutting (it engraves white), but has slightly variable thickness tolerances. Extruded Acrylic is pushed through rollers. It has very consistent thickness and is cheaper to make in markets of high demand, making it ideal for glazing, but it can melt if laser cut or drilled at high speeds. We primarily stock Cast Acrylic for its superior fabrication qualities
