Poly(methyl methacrylate) [i.v. 1.25] is a transparent acrylic polymer supplied for research, formulation, and materials development applications. PMMA is valued for optical clarity, rigidity, dimensional stability, and compatibility with common organic solvents used in polymer processing.
Synonyms: PMMA; poly(methyl methacrylate); acrylic polymer.
This PMMA grade has a molecular weight of approximately 500,000 based on viscosity and is commonly used where a high-molecular-weight acrylic resin is required for films, coatings, molded materials, polymer blends, and optical or materials research.
Researchers and technical buyers use PMMA in studies involving acrylic polymer behavior, transparent thermoplastic materials, surface coatings, polymer compatibility, and specialty material development.
