4 X 8 X 4mm Acrylic Sheet, Clear

Specifications: material is clear acrylic (PMMA), size 4" x 8", thickness 4 mm, optically transparent, UV resistant, relatively scratch resistant, easy to cut and shape, suitable for indoor and some outdoor applications.

Use a sharp blade or scored-cut method for straight cuts, with masking tape to prevent chipping. For drilling, use a clean drill bit, drill at moderate speed with a pilot hole, and deburr edges after cutting. Always wear eye protection and handle edges carefully.

Clean with mild soap and water or a dedicated acrylic cleaner. Wipe with a soft microfiber cloth to avoid scratches. For sticky residues, use a small amount of isopropyl alcohol. Avoid ammonia-based cleaners that can craze the surface.

Yes, the sheet is UV resistant, which helps resist yellowing and degradation from sun exposure. For prolonged outdoor use, periodic cleaning and protection from physical abrasion will help maintain clarity.

Fepy offers other clear acrylic sheets in different thicknesses. For example, 4x8x2mm, 4x8x3mm, and 4x8x5mm options are available to suit rigidity and weight needs. Compare them to 4x8x4mm to choose the right balance of strength and flexibility. Products you can explore: 4x8x2mm (https://fepy.com/product/clear-acrylic-sheet-4x8x2mm), 4x8x3mm (https://fepy.com/product/clear-acrylic-sheet-4x8x3mm), 4x8x5mm (https://fepy.com/product/clear-acrylic-sheet-4x8x5mm).

Mounting options include clear adhesive films or double-sided tape for light-duty setups, clamps or brackets for better support, and appropriate fasteners if mounting through holes. Deburr edges after cutting, and consider using protective films during handling to reduce scratches.

Common uses include signs, displays, model making, small window panels, DIY crafts, surround panels for displays, and decorative accents in furniture or display cases.

Yes. Wear eye protection and gloves when cutting or drilling, handle edges carefully to avoid cuts, work in a well-ventilated area, and deburr sharp edges after processing. Store sheets flat or upright to prevent warping and edge damage.

Yes. Vinyl decals adhere well to clean acrylic surfaces. If painting, use acrylic-based paints with appropriate primers designed for plastic, and test a small area first to ensure proper adhesion and finish.

A 4 mm thickness provides a good balance of rigidity and weight for many DIY projects. It’s sturdier than 2 mm or 3 mm sheets while remaining lighter and more cost-effective than thicker sheets like 5 mm in many applications. Choose based on needed rigidity, impact resistance, and handling ease.
