Short answer: Frosted acrylic usually means sheet with a matte, satin texture on one or both sides, such as Acrylite Satinice, which blurs what's behind it while still passing about 88 to 92% of light. You can also frost just the edges by sanding, frost a design by laser engraving clear acrylic, or use white translucent acrylic, which hides light sources far better but passes only about 30 to 55%. Pick frosted sheet for privacy panels, engraving for patterns, and white translucent for even light in signs and light boxes.
Key facts
- Frosted sheet light transmission (Acrylite Satinice, colorless): velvet texture one side 92%, both sides 89%; crystal surface one side 92%, both sides 88%.
- Frosted-through sheet (diffuser beads in the sheet): 72 to 92% colorless, depending on grade; edges are frosted too.
- White translucent: 7328-type white about 31 to 32% and 2447-type about 53 to 54% at 1/8 in., less in thicker sheet.
- Textured faces only: on surface-frosted sheet, the cut edges stay glossy unless you sand them.
The four kinds of frosted acrylic
| Option | What it is | Looks like | Best for |
|---|---|---|---|
| Frosted sheet | Acrylic made with a matte texture on one or both faces | Etched glass: soft, satin, shapes visible as blurs | Privacy panels, cabinet inserts, dividers, diffusers |
| Sanded or frosted edges | Clear acrylic with the cut edges sanded to a satin finish | Clear face with a soft, matte edge | Signs, shelves, and displays where glossy edges aren't wanted |
| Engraved frosting | Clear acrylic with areas frosted by laser engraving | Clear sheet with a crisp frosted pattern, logo, or band | Decorative privacy, door glass looks, logos, awards |
| White translucent | Acrylic colored milky white through the sheet | Solid white that glows when lit from behind | Light boxes, backlit signs, LED diffusers |
Frosted sheet: matte on one side or both
Frosted acrylic sheet has its texture made in during production, so the surface is even across the whole sheet. Acrylite sells it as Satinice in several textures: a soft “velvet” matte on one or both sides, a “crystal surface” that looks like etched glass, and an “optimum light diffusion” grade with diffuser beads through the whole sheet. Plaskolite makes frosted and matte Optix grades too.
- Matte on one side looks glossy from the smooth side and satin from the textured side. It's common for cabinet doors and wall panels, where one face shows.
- Matte on both sides looks the same from either side and hides what's behind it a bit more, which suits room dividers and freestanding panels.
Frosted sheet still lets nearly all the light through; the texture just scatters it. Objects pressed against the sheet stay fairly visible, while anything a few inches back becomes a soft shape. How strong the frost is varies by product. We stock frosted in 1/8 to 3/8 in.
Sanded or frosted edges
A laser-cut edge on acrylic is glossy and clear, and so is the edge of most frosted sheet. Some designs look better with a soft, matte edge instead, especially modern signs and displays. We can sand the edges of clear or colored acrylic to an even satin finish, or machine them to a smooth satin edge. This changes only the edge, not the face. See edge finishes.
Engraved frosting on clear acrylic
Laser engraving clear cast acrylic leaves a fine white frost, so you can frost exactly the areas you want: a band across a cabinet door at eye level, a pattern, a logo, or the whole sheet except a clear border. Large engraved areas take time and cost more than frosted sheet, so for a fully frosted panel, frosted sheet is the better buy. For a design, engraving is the only way. See acrylic engraving.
White translucent: the best diffuser
White translucent acrylic has white pigment mixed through the sheet, so it scatters light from inside rather than only at the surface. It hides LEDs and fluorescent tubes much better than frosted sheet, giving an even glow without hot spots. The cost is brightness. Acrylite's data for extruded white: the 2447-type passes 54% at 1/8 in., 43% at 3/16 in., and 35% at 1/4 in.; the denser 7328-type passes 31%, 23%, and 18%. Because the pigment level stays the same, thicker white sheet is always dimmer. Read more in acrylic light transmission and see LED light diffusers.
Which is best for privacy?
For a window, bathroom door insert, or divider where you want light but no clear view, frosted sheet is usually the right balance. Double-sided frost or white translucent hides more. Keep in mind that any surface-frosted sheet becomes more see-through when it's wet or when something presses against it, and any of them show a silhouette when one side is much brighter than the other, such as a lit room at night. For room dividers and cabinet door inserts, we cut frosted sheet to size with clean edges.
Which is best for diffusing light?
- Frosted sheet: brightest, but you may still see individual LEDs if they're close to the panel.
- Bead-filled diffusion sheet: a middle ground; Acrylite's colorless optimum light diffusion grades pass 72 to 92%.
- White translucent: the most even light, noticeably dimmer.
- Distance helps every option. Moving the LEDs farther from the diffuser evens out the light more than any material change.
Fingerprints and cleaning frosted acrylic
Matte surfaces show fingerprints and oily smudges more than glossy ones, because skin oil fills the texture and makes a darker, clearer patch. To clean:
- Rinse or wipe off grit first so you don't grind it into the texture.
- Wash with warm water and a little dish soap, using a soft cloth or sponge.
- Rinse and blot dry with a microfiber cloth.

Questions
Can you engrave frosted acrylic?
Yes, but the engraving shows less contrast than on clear, since the surface is already matte. Engraving on the glossy side of single-sided frosted sheet gives the best result.
Can I frost clear acrylic myself?
You can sand it evenly with fine sandpaper, but getting a uniform look over a large panel is hard. Frosted sheet or engraving gives a more even finish.
Can frosted acrylic be used outdoors?
Yes. Acrylite says Satinice keeps the same physical properties as its standard cast sheet, so it weathers like clear. The texture can collect dirt over time, so face it to the inside where you can.
Is frosted acrylic the same as white acrylic?
No. Frosted acrylic is clear acrylic with a textured surface, so it passes about 88 to 92% of light and looks icy. White translucent is pigmented through the sheet, passes about 30 to 55%, and looks solid white.
