Glycolic acid, also known as glycolic acid and glycolic acid, is also an important organic synthesis intermediate and chemical product. It is widely used in organic synthesis, cleaning, electroplating, textile, leather, sterilization and other industries. In recent years, scientific research has found that glycolic acid polymers are biodegradable, which solves the problem of difficult degradation of traditional plastic products. They can be widely used in medicine, packaging and many other fields.
