What is so special about PGA ?
Although PGA is also a plastic product in terms of attributes like traditional plastic products, it has its revolutionary and subversive characteristics with traditional plastic products.
Its biggest feature is that the product has good biodegradability and biocompatibility, as well as high mechanical strength, excellent formability and excellent gas insulation.
PGA can be completely degraded, and the degradation products are harmless
PGA degradation conditions are mild, under the action of water and microorganisms, it can achieve rapid degradation in the natural environment, and the degradation products are harmless to humans and the environment. Therefore, it has good applications in agricultural and forestry production, packaging materials, and disposable environmental protection products. for example:
Used in packaging film, plastic bag, agricultural film, stretch film and other film markets; used in food packaging, cling film and other composite film markets; used in the one-time washing market such as toothbrushes, combs, and dental floss; used in knives, forks, spoons, etc. Tableware market such as straws; used in plastic containers such as lunch boxes, cups, cake boxes, etc.; used in daily life, industry, and engineering fields.
Can be degraded in seawater, reducing white pollution
In addition, PGA has excellent seawater degradation properties. PGA can be degraded in seawater without special conditions for degradation, and can be completely decomposed into carbon dioxide and water after degradation. Can effectively solve the problem of white pollution.
Other materials used in conjunction with PGA to obtain "attribute blessing"
On the other hand, PGA is also an ideal biodegradation inducer. Usually PGA is used in conjunction with other materials to improve the overall overall performance. For example, a straw made of PGA and PLA blended modified materials not only has the characteristics of water resistance, grease resistance, and high temperature resistance, but also has better degradation performance than pure PLA products.
Degradable in the human body, widely used in the medical field
PGA has good biocompatibility. It can be degraded into water and carbon dioxide in the human body. Therefore, it is widely used in medical surgical sutures, internal fixation of fractures, tissue engineering repair materials and drug controlled release systems.
This is an important branch of current biomedical polymers, and global medical expenditures continue to increase, which has also promoted the increase in the demand for polyglycolic acid.
Can be used in the field of oil and gas exploration
Typical applications of PGA in the oil and gas market include soluble bridge plugs, soluble fracturing balls, temporary plugging agents and temporary plugging balls. With the promotion of PGA materials, PGA will find more new applications in the field of oil and gas production, such as drilling fluid additives, slow release agents, fracturing proppants, fluid loss additives, etc.
