polymethylmethacrylate

polymer

Polymethylmethacrylate (PMMA), commonly known as acrylic, is a transparent thermoplastic polymer valued for its optical clarity, rigidity, and ease of processing. It is widely used in applications requiring both transparency and dimensional stability, from consumer goods to precision optical components, where it often serves as a lightweight, shatter-resistant alternative to glass. PMMA's combination of good weathering resistance and moderate mechanical strength makes it particularly suitable for outdoor and long-term exposure applications.

Regulatory Screening

Environmental

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
