Lightweight plastic with glass-like clarity and a smooth feel.
What it is
Acrylic, or PMMA (polymethyl methacrylate), is a clear, rigid plastic often sold under names such as Plexiglas. It offers glass-like clarity at a fraction of the weight and is easy to machine, polish and laser cut. In EDC, it appears in clear or colored bodies, windows, layers and display cases. The exact grade and color depend on the brand.
How it feels in your EDC
Acrylic is light and feels smooth, hard and slightly glossy in hand. It is very clear and takes a bright polish, so it can show off internal parts or add a clean, glass-like accent. It is more rigid but less impact resistant than Polycarbonate, and a piece built with it feels lighter than a metal version.
Care & aging
Acrylic scratches more easily than glass and can crack if dropped hard, especially at thin edges or around holes. Clean it with a soft cloth and mild soap. Avoid solvents such as acetone and alcohol-based cleaners, which can cause fine cracks called crazing. Light surface scratches can sometimes be buffed out with a plastic polish.
是什么
亚克力，即 PMMA（聚甲基丙烯酸甲酯），是一种透明坚硬的塑料，常以 Plexiglas 等名称销售。它有玻璃般的通透度，重量却轻得多，而且容易加工、抛光和激光切割。在 EDC 中见于透明或彩色的主体、视窗、夹层和展示盒。具体牌号和颜色取决于品牌。
上手感受
亚克力很轻，握感顺滑、坚硬、略带光泽。它非常通透，可以抛出明亮光泽，能展示内部零件，或作为干净的玻璃质感点缀。它比聚碳酸酯更硬，但抗冲击性较差；用它制作的作品比金属版本更轻。
保养与老化
亚克力比玻璃更容易划伤，重摔时可能开裂，薄边和孔位周围尤其如此。用软布和温和的肥皂清洁。避免丙酮和含酒精的清洁剂，它们可能导致细微裂纹（银纹）。轻微的表面划痕有时可用塑料抛光剂打磨掉。
