What is extruded acrylic?
- Extruded acrylic has a more constant width than cast acrylic.
- Best to vacuum shape, bend or heat. Can be more susceptible to crack, in a few situations.
- Good quality extruded acrylic gives a very clean, smooth edge when laser cut.
What is cast acrylic?
- The thickness tolerance in cast acrylic varies more than in extruded acrylic.
- More expensive than extruded, but more versatile.
- Very strong acrylic, won’t warp when heated.
- Can handle impacts better, resists scratching.
- When engraved, it will leave a smooth, frosty white color.
- Acrylic becomes very statically, and will attract dust.
- You can use an anti-static or silicone lubricant spray to help prevent the dust from sticking.
- Crazing is defined as a hairline crack that can be the result of a stress or chemical damage to the acrylic.
- Will make the acrylic weaker, and make the appearance not desirable.
- Best way to prevent is to avoid using certain types of cleaners, and avoid high stress to the acrylic.
- Use a non-abrasive fabric, like a microfiber cloth.
- May use a small amount of mild detergent, but don’t put too much pressure on the acrylic
Don’t use cleaners that contain alcohol, bleach or ammonia – this will probably cause crazing.
