Poly(isobutyl acrylate)

polymer

Poly(isobutyl acrylate) is a soft acrylic polymer synthesized from isobutyl acrylate monomers, belonging to the family of acrylate-based plastics. It is primarily used in adhesive formulations, coatings, and elastomeric applications where flexibility and low-temperature performance are required. Engineers select this material for pressure-sensitive adhesives, flexible sealants, and soft-touch coatings because its low glass transition temperature enables conformability and tackiness without requiring plasticizers that might migrate or compromise durability.

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.
