AcrylicFabWorks Publishes Specification Guide for Scratch-Resistant Acrylic
Scratch-Resistant Acrylic: How to Specify and Test It
AcrylicFabWorks, the acrylic division of SinoPlastix, released a technical guide detailing how to specify and test scratch-resistant PMMA using pencil hardness (ASTM D3363), Taber abrasion haze increase (ASTM D1044), and steel wool rub tests with defined load and strokes.
Hard-coated PMMA improves wipe and abrasion resistance but restricts fabrication: coated sheet cannot be tightly bent or thermoformed without cracking the coating, cut edges remain uncoated, and polishing removes the coating entirely. Specifying pencil hardness (ASTM D3363), Taber haze increase (ASTM D1044), or steel wool rub with stated load and strokes is essential for verifiable acceptance.
