PMAA

polymer

PMAA (polymethacrylic acid) is a synthetic polymer belonging to the family of acrylic polymers, characterized by pendant carboxylic acid groups along its backbone that enable pH-responsive behavior and strong hydrogen bonding. It is widely used in biomedical and chemical engineering applications including controlled drug delivery systems, water treatment, adhesives, and superabsorbent materials, where its ability to swell and change properties with pH variation is exploited. Engineers select PMAA when pH-dependent functionality, mucoadhesion, or chemical reactivity of the polymer backbone is required—applications where conventional neutral polymers would be inadequate.

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.
