Polymethyl Methacrylate (PMMA), also known as acrylic resin, is a high-transparency thermoplastic engineering material supplied in uniform pellet form. As a premium alternative to inorganic glass, it combines exceptional optical performance, outstanding weatherability and reliable processability for wide industrial applications.
Suitable for complicated shape and longmolding path, such as handicrafts, packagingboxes, home appliances, thin-wall crafts, nameplates.
