AdminShort answer: Polycarbonate is the tough, impact-resistant clear plastic; acrylic (PMMA) is the clearer, harder and more scratch-resistant one. Choose polycarbonate for guards, covers and anything that may be hit, and acrylic for displays, light fittings and polished clear parts. As a polycarbonate sheet supplier saudi arabia, Diode Trading EST stocks both in Dammam.
Both materials look similar on the shelf, yet they behave very differently once they are cut, bent, exposed to sun or struck. Picking the wrong one is a common and avoidable mistake.

Polycarbonate has very high impact strength, many times that of acrylic and far above glass. It stays tough at low temperatures, handles higher heat than acrylic, and can be cold-bent without cracking. Typical uses include:
If you are comparing a pc sheet distributor ksa against other sources, check whether the sheet is UV-protected for outdoor jobs. Standard polycarbonate can yellow and lose gloss in strong sun, and its surface scratches more easily than acrylic. Some solvents and cleaners can also cause stress cracking, so avoid aggressive cleaners.
Acrylic offers excellent optical clarity, a glossy surface and good weather resistance. It is stiffer and harder than polycarbonate and can be flame-polished to a clear edge, but it is more brittle and will crack under sharp impact.
Buyers looking for an acrylic sheet and rod supplier saudi arabia usually need clear sheet for displays, signage, point-of-sale stands, aquarium and showroom fittings, and light diffusers, plus acrylic rod and tube for fabricated and decorative parts. Acrylic bonds well with solvent cement, giving almost invisible joints.
| Property | Polycarbonate | Acrylic (PMMA) |
|---|---|---|
| Impact strength | Very high | Moderate, brittle |
| Clarity | Good | Excellent |
| Scratch resistance | Lower | Higher |
| Heat resistance | Higher | Lower |
| Outdoor UV | Needs UV grade | Good weathering |
| Bending | Cold-bends easily | Heat-bend only |
| Typical use | Guards, covers, housings | Displays, signs, lenses |
Figures vary between manufacturers, so check the data sheet when the part is critical.
Both sheets can be sawn, routed, drilled and laser or CNC cut. Some practical points:
Ask what will happen to the part. If it may be struck, dropped or vandalised, choose polycarbonate. If it will be viewed closely, polished, or exposed to cleaning and sunlight, acrylic is usually better. For outdoor impact duty, specify UV-stabilised polycarbonate and say so when you order.
Solid polycarbonate and acrylic sheets come in a range of thicknesses from thin cover sheet to heavy plate for machine guards. Thicker sheet gives better stiffness and impact resistance, but it also costs more and is harder to bend. As a rule, guards that may be struck need a thicker polycarbonate than a simple cover that only keeps dust out.
When requesting a quote, include the finished size, thickness, colour (clear, tinted or opal), whether you need UV protection, and any special finish such as anti-scratch coating. For rod, state the diameter and length. Clear information avoids returns and makes the quote faster.
Wash both materials with mild soapy water and a soft cloth. Avoid abrasive pads, ammonia-based glass cleaners and strong solvents, which can craze acrylic or stress-crack polycarbonate. Rinse and dry with a clean microfibre cloth. For light scratches on acrylic, plastic polish can restore the surface, whereas polycarbonate generally needs replacement or a hard-coated grade from the start.
Both sheets expand and contract with temperature, so leave a small gap in frames and use slotted or oversize holes for fixings. Over-tightening bolts creates stress points that later turn into cracks.
A final practical point is lead time on projects. Guards, covers and displays are often needed at the end of a job, when schedules are tight. Because we hold sheet in stock, you can confirm availability early and avoid last-minute substitutions. If the exact thickness you want is unavailable, we can suggest the nearest suitable option rather than leave you with a gap in the schedule.
Yes. Polycarbonate has far higher impact resistance, while acrylic is harder and clearer.
Acrylic weathers well. Polycarbonate works outdoors only in a UV-protected grade.
