PMMA Bone Cement

PMMA bone cement is an acrylic polymer formulated specifically for orthopedic and dental fixation, typically supplied as a two-component system (powder and liquid monomer) that polymerizes in situ to create a rigid, biocompatible interface. It is widely used in joint replacement surgery, spinal instrumentation, and dental prosthetics to mechanically interlock implants with bone and provide load transfer; engineers select it for its established biocompatibility, ease of application, and decades of clinical track record, though it is gradually being supplemented by newer formulations offering improved mechanical properties and reduced exothermic curing reactions.

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.
