PMA
polymerPMA (polymethyl acrylate) is an acrylic polymer known for its excellent flexibility and transparency, belonging to the family of acrylate-based thermoplastics. It is widely used in adhesives, coatings, sealants, and flexible films where resilience and elongation are critical, as well as in some elastomeric compounds and latex formulations. Engineers select PMA when high extensibility combined with adequate modulus and thermal stability is required, particularly in applications where brittleness must be avoided and environmental durability is important.

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.
