SRT Frosted Acrylic Sheet (PMMA-Frost)

Velvety Aesthetics & Practical Durability

Standard frosted acrylics often suffer from showing fingerprints and scratching easily. SRT PMMA-Frost utilizes a specialized surface treatment that creates a velvety, warm texture that is insensitive to fingerprints and offers superior abrasion resistance compared to standard plastics. This makes it ideal for high-traffic areas where aesthetics must be maintained without constant cleaning.

Optical Diffusion & LED Performance

With a light transmission of 70% and a half-power angle of 56°, SRT PMMA-Frost is an excellent diffuser. It effectively hides the filaments of LED bulbs, transforming harsh point sources into a soft, uniform glow. This makes it a preferred choice for sophisticated backlighting, architectural luminaires, and privacy glazing where light is needed but visibility must be obscured.

Processing & Finishing

Despite its textured surface, SRT PMMA-Frost retains the fabrication versatility of standard acrylic. It can be laser cut, and unlike many textured sheets, the edges can be polished to a high gloss without affecting the surface finish. It bonds well with solvent adhesives and can be thermoformed into curved diffusers or furniture components.

Typical Use Case

Widely used for privacy partitions in open-plan offices and medical waiting rooms. The dual satin/matt texture diffuses light to maintain an airy feel while obscuring direct visibility. Crucially, its resistance to fingerprints means it stays looking professional even in high-touch areas where staff and patients frequently interact.
