Poly(butyl acrylate)

polymer

Poly(butyl acrylate) is a synthetic elastomeric polymer formed by polymerization of butyl acrylate monomers, belonging to the family of acrylic rubbers. It is widely used in adhesives, coatings, and sealants where flexibility and low-temperature performance are required, as well as in pressure-sensitive applications and elastomeric components. The material is valued for its balance of processability and rubbery properties, making it a practical choice for engineers needing a softer, more flexible alternative to rigid acrylic polymers in applications where environmental resistance and adherence are important.

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.
