PMMA Powder (Polymethyl Methacrylate)
PMMA (acrylic) powder is supplied in free-flowing form for coating, casting, and specialty processing applications. It offers outstanding optical clarity and weather/UV stability compared with many commodity plastics. Typical particle size ranges from roughly 20 to 100 µm depending on grade; particle size and specific grade are confirmed at time of quotation.
