PMMA
General-purpose transparent unmodified PMMA is a basic-grade polymethyl methacrylate produced from methyl methacrylate (MMA) via bulk or suspension polymerization without fillers or modifiers. It features exceptional light transmittance (≥92%), excellent weather resistance, and good mechanical strength. As the earliest commercially produced acrylic material, it is widely used in general applications requiring optical clarity and aesthetic quality.

Application：
- Lamp covers, fluorescent lamp covers, LED diffusers
- Advertising signage, display stands, neon housings
- Sanitary ware (bathtubs, basins, shower enclosures)
- Architectural decoration (skylights, partitions, handrails)
- General optical lenses, protective face shields
