Ring-opening polymerization of glycolide can be catalyzed using different catalysts, including antimony compounds, such as antimony trioxide or antimony trihalides, zinc compounds (zinc lactate) and tin compounds like stannous octoate (tin(II) 2-ethylhexanoate) or tin alkoxides. The degradation process is erosive and appears to take place in two steps during which the polymer is converted back to its monomer glycolic acid: first water diffuses into the amorphous (non-crystalline) regions of the polymer matrix, cleaving the ester bonds; the second step starts after the amorphous regions have been eroded, leaving the crystalline portion of the polymer susceptible to hydrolytic attack. China Polyglycolic Acid Suture manufacturers - Select 2020 high quality Polyglycolic Acid Suture products in best price from certified Chinese Surgical Suture manufacturers, Surgical Instrument suppliers, wholesalers and factory on Made-in-China.com - Polyglycolic acid (PGA) is a synthetic surgical suture characterized by exceptional tensile strength and in-vivo inertness - Rapid Polyglycolic Acid (PGAR) is intended to be used in soft tissues where only short term wound support is required, and where rapid absorption of the suture is needed [2] Degradation is faster in vivo than in vitro, this phenomenon thought to be due to cellular enzymatic activity.[10]. Manufacturer & Exporters of Polyglycolic acid sutures in Bangalore India. Minimal. Other brands of polyglycolic acid suture include PolySyn, Surgicryl, Polysorb, and Dexon, all of which are manufactured by different companies.
