POLYGLYCOLIDE CAS 26124-68-5, also known as PGA, is a simple linear aliphatic polyester with a simple and regular molecular structure. PGA has a high crystallinity and forms crystalline polymers. The crystallinity is generally 40%~80%. The melting point is about 225 ℃. PGA is insoluble in common organic solvents and only soluble in strong polar organic solvents such as hexafluoroisopropanol.

In the biomedical field, PGA is one of the most established materials due to its excellent biocompatibility and biodegradability. Its primary and most renowned application is in the production of bioresorbable surgical sutures, which maintain wound closure integrity and then safely dissolve in the body . Beyond sutures, it is extensively used in other implantable medical devices such as pins, screws, and rods for bone fixation, as well as in tissue engineering scaffolds that support cell growth for regeneration . Furthermore, PGA serves as a key material in drug delivery systems, functioning as a carrier for the controlled and sustained release of therapeutic agents .
In the oil and gas industry, PGA is utilized for its ability to degrade under downhole conditions. It is employed in the manufacture of temporary tools and additives for hydraulic fracturing, such as dissolvable bridge plugs, fracturing balls, and temporary diverting agents . These components perform their function during the fracturing process and then degrade, eliminating the need for costly and time-consuming retrieval operations.
In the packaging sector, PGA’s exceptional gas barrier properties—significantly restricting the transmission of oxygen and water vapor—make it a highly attractive material for creating high-performance, fully biodegradable packaging films . It is used to enhance the barrier performance of other biodegradable polymers in blends, offering a sustainable alternative to traditional non-degradable packaging for food and other goods . Its applications also extend to the production of biodegradable molded parts and disposable items like cutlery, cups, and containers .
Other notable applications include its use in agriculture as biodegradable mulch films that can be plowed into the soil after use, eliminating the pollution associated with conventional plastics . It can also be processed into fibers for non-woven textiles and hygiene products , and used as a modifier in engineering plastics to enhance the toughness of polymer blends .
Usually packed in 25kg/drum,and also can be do customized package.
