What materials does pipe filling include?

Due to the rising energy prices and the increasingly prominent environmental problems, biodegradable biomaterials have gradually accelerated the trend of replacing traditional petroleum products in the world. It is expected that the government will also introduce relevant preferential policies and laws and regulations to encourage the market application. The large-scale application of biodegradable materials has broad prospects.

Pipeline fillers include polymers prepared directly through biotechnology, such as polyhydroxyfatty acid ester (PHA), etc. A class of materials prepared by biotechnology and then by polymerization, such as polylactic acid (PLA), polybutylene succinate (PBS), polyamino acid, etc.; In addition, there are starch-based biodegradable plastics, carbon dioxide copolymer aliphatic polycarbonate (APC), etc.

Starch-based biodegradable plastics are plastic products made by starch modification, grafting reaction and other polymer blending, which can replace ordinary plastics and be used in industrial production. They can be used as packaging materials, impact resistant materials, films, food containers, toys and so on.

Is composed of lactic acid polymerization of poly (lactic acid) (PLA) polymer materials, has a non-toxic, no stimulation, high strength, easy to processing molding as well as the characteristics of good biocompatibility, the product can completely be degraded after use, is the real realization of ecological and economic dual effect of biological environmental protection material, is developed in recent years is the most active and fastest growing biodegradable plastics.

The polybutylene succinate obtained by polycondensation of succinic acid and butanediol is internationally recognized as a biodegradable plastic with high comprehensive performance. Due to its excellent comprehensive performance and reasonable cost performance, PBS is widely used in packaging, tableware, cosmetic bottles and medicine bottles, disposable medical supplies, agricultural film, pesticide and chemical fertilizer sustained-release materials, biomedical polymer materials, etc.
