Acrylic sheeting and Polycarbonate sheeting are not the same. So how do you choose the right material for the job? Luckily while they look similar, their properties are very different. Here's what you need to know.
Acrylic v polycarbonate - An overview of the differences
Both materials feature impressive impact resistance. Both compare well with glass, making good glass alternatives. And they both weigh less than half the weight of glass.
- Sheet grade polycarbonate is also called Lexan or Makrolon. Acrylic sheet is also called Lucite, Optix or Plexiglass
- Polycarbonate is the strongest, with more than 30 times the impact resistance of glass. Acrylic has 10-24 times the impact resistance of glass
- As a general rule, acrylic sheet is more shiny and polycarbonate is stronger
- Acrylic comes in every imaginable colour. Polycarbonate comes in fewer colours
- Polycarbonate can go slightly yellow when exposed long-term to UV rays
- Both materials can suffer scratches, so you can't use abrasive cleaning materials on them. But it's easier to repair scratches in acrylic than polycarbonate
- Acrylic tends to be a bit clearer than polycarbonate, slightly more transparent
- Polycarbonate usually costs more than acrylic, sometimes a lot more
- Acrylic is easier to cut. Polycarbonate is better if you need to drill, and you can use a standard drill bit
- Acrylic is easier to break, especially if you drill close to the edge
- Acrylic sheet can be polished to a smooth finish, but you can't polish polycarbonate
- Acrylic is extremely rigid and cracks more easily than polycarbonate. Polycarbonate comes in both rigid and flexible grades
- Acrylic isn't recommended in areas close to fire or heat. Polycarbonate is better at handling heat, up to 115 C, and is resistant to fire as well as acids and other chemicals
- Polycarbonate is good for cold-forming and bending without heat, but it also dents easily
- Both are salt-resistant so good for coastal areas
- Both are 100% recyclable
When you can use polycarbonate combined with acrylic
Polycarbonate is your ideal composite material for things like bulletproof glass and riot shields. Its high impact strength and high light transmission make it ideal for greenhouses. Acrylic, like polycarbonate, has very high light transmission, but is also extremely scratch resistant. This makes it ideal for optical devices, being safer and stronger than glass.
They can also be used in conjunction, for example in shop windows made from layers of acrylic and polycarbonate, in situations where scratch resistance matters just as much as safety and strength. You might, for example, make a shop window from outer layers of acrylic fused around an inner layer of polycarbonate.
Popular uses for acrylic sheet
Knowing its uses is often the easiest way to decide which material you need. Here are some of the most popular uses for acrylic plastic sheets.
- Fish tanks and vivariums
- Retail point of sale displays
- Kitchen and bathroom splashbacks
- Presentation boards for businesses
- Displays for retail, schools, colleges, boardrooms and more
- To clad walls and old kitchen cabinet doors
- To replace glass in furniture
- As signage
- For craft projects and artwork
- To make contemporary shelving
- As a safer, lighter, cheaper alternative to glass in picture frames
- To replace small glass windows
Popular uses for polycarbonate sheet
Here are some of the commonest uses for polycarbonate sheeting.
- Racing car windows
- Transparent visors for sport
- Re-usable drinking bottles
- Computer, phone and tablet screens
- Machine safety guards
- Bullet proof glass, security glass and safety goggles
- Semiconductor parts
- Name plates and signage
- Greenhouses, carports and conservatories
- Roofing and trims
- Bus shelters
- As a replacement for glass in buildings, for example skylights.
Polycarbonate versus acrylic - The differences in cost
Polycarbonate is more expensive than acrylic, approximately 45% more than our acrylic prices. However this additional cost does guarantee you the strongest plastic we have available.
The best material for kitchen splashbacks and bathroom splashbacks?
Colourful contemporary splashbacks are all the rage. But you need to take care in hot places.
Don't use acrylic sheeting behind or too near to a gas or electric cooker, hob, open fire, wood burner, Rayburn, Aga or any other source of heat. If the area is likely to get hotter than 160°C it can damage the acrylic, so we advise against it. Why not check out our beautiful range of glass instead?
If you have an induction or electric hob, you can fit a continuous acrylic splashback along the entire wall as long as you make sure there's a minimum 50mm gap between the hob and the panel. The panels are 300cm long, so if the wall is any longer you'll need a second panel. But if your gas hob cooker runs along the wall where you want the kitchen splashbacks to go, you'll need to fit a special toughened glass splashbacks.
Acrylic versus glass
- Acrylic is less than half the weight of glass
- It is many times stronger than glass
- When it shatters you get big chunks with blunt edges, much safer than glass shards
- Acrylic insulates better than glass
- Moulded and extruded glass items are more expensive and take more energy to make
- You can't saw, mill or bend glass and it's difficult to form with heat
- Glass is harder to scratch but acrylic sheets sometimes come with a scratch-resistant coating
- Small scratches can be polished out of acrylic but you have to replace scratched glass
- Glass lets 90% through, acrylic lets 92% through
- Acrylic prevents UV light passing through.
Polycarbonate versus glass
- Almost unbreakable, a clear advantage over glass
- Can withstand extreme force
- Protects better against vandalism and theft, 250 times more resistant to impacts than glass
- Withstands extreme temperatures for long periods
- Lasts longer than glass
- Offers better insulation than glass, with excellent thermal efficiency
- The light it lets in is softer than glass, protecting plants in greenhouses
- Polycarbonate sheet is six times lighter than glass, so safer and easier to install
- You can cut it with a standard circular saw, impossible with glass
- It's easy to cut and form, and can be cut on-site.
Unusual and creative uses for our plastics
One of our customers got creative with acrylic sheet, replacing a dangerous glass tabletop with something safer, lighter and tougher. It's far better for his autistic grandson, who had broken the original glass top and was lucky not to be injured.
