Poly(isobutyl methacrylate)
polymerPoly(isobutyl methacrylate) (PIBM) is an acrylic polymer derived from isobutyl methacrylate monomers, belonging to the methacrylate family of thermoplastic resins. It is used primarily in adhesive formulations, coatings, and elastomeric applications where flexibility and adhesion to diverse substrates are required. PIBM is valued in pressure-sensitive adhesives, sealants, and specialty coatings due to its ability to balance flexibility with surface tack, making it a preferred choice over brittle acrylics in applications demanding impact resistance and conformability.

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.
