poly(butyl methacrylate )
polymerPoly(butyl methacrylate) is an acrylic polymer belonging to the methacrylate family, characterized by a butyl ester side chain that imparts flexibility and low-temperature performance to the backbone. It is commonly used in coatings, adhesives, and elastomeric applications where a combination of durability and flexibility is required, particularly in automotive refinishes, pressure-sensitive adhesives, and flexible sealants. Engineers select this material over rigid acrylics when low-temperature impact resistance and adhesion properties are critical, though it typically trades some hardness and modulus for improved elasticity and processability.

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.
