Monomer

High-purity monomer feedstock.

Modern Bridge supplies medical-grade glycolide and L-lactide — the raw material behind
every bioresorbable polymer we source, with each grade verified by GC purity,
moisture and acid-value testing before release.

Modern Bridge glycolide monomer — white crystalline powder
Glycolic Acid Dimer

Glycolide

C₄H₄O₄

A high-purity monomer supplied as the raw material for medical-grade biodegradable polymers such as PGA and PGLA. Every lot ships as a white crystalline powder in a sealed aluminum pouch, released only after GC purity, moisture and acid-value testing.
