Smooth acrylic sheet can work as a dry-erase surface because PMMA is nonporous. Technical guidance for dry-erase markers confirms that the ink wipes from most nonporous materials. Clear or glossy white acrylic normally performs better than frosted, textured, mirrored, or coated sheets, where ink may enter surface patterns and leave ghosting.
Write on a sample with the intended marker, erase it after one hour and again after 24 hours, then inspect it under strong light. Use a soft microfiber cloth and an acrylic-compatible cleaner. Avoid abrasive pads and strong solvents that may scratch, haze, or stress the surface.
ISO 7823-1 covers cast PMMA sheets from 1.5 to 25 mm. ISO 7823-2 covers extruded PMMA sheets from 1.5 to 20 mm. Select the thickness according to panel size, support method, writing pressure, and installation conditions.
A manufacturer can control resin grade, extrusion, gloss, color, thickness, cutting, polishing, printing, and protective film. A trader normally depends on separate suppliers, making surface consistency and corrective action less direct.
With more than 10 years of acrylic, polycarbonate, and polystyrene sheet experience, we support OEM and ODM projects from drawing review and sample testing to extrusion, CNC cutting, printing, inspection, and packing. Our automated lines provide monthly processing capacity of about 600 tons.
Confirm the sheet type, gloss, thickness, dimensions, backing color, edge finish, mounting holes, printed grid, marker compatibility, cleaning method, packaging, and tolerances.
Quality checkpoints should cover flatness, scratches, color consistency, erasability, repeated-cycle ghosting, dimensions, and protective-film condition. Export orders should also confirm ISO 9001 controls, RoHS or REACH documents when required, labeling, traceability, and pallet protection.
