| description | The invention discloses a high-flexibility polyamide natural gas pipe material which is prepared from the following components in parts by weight: 70-94 parts of polyamide, 4-20 parts of a toughening agent, 2-15 parts of a plasticizer, 0.3-1.5 parts of a heat stabilizer, 0.4-1 part of weather-resistant auxiliaries and 0.3-1 part of an additive. The high-flexibility polyamide natural gas pipe material has very excellent flexibility and excellent aging resistance, and the technical problem to be solved is to select PA616, PA618 and other long-carbon-chain nylon as main raw materials and improve the toughness of the material in a toughening and plasticizing manner, so that the material has excellent low-temperature toughness. By adding the heat stabilizer and the weather-resistant auxiliaries, the material has excellent heat resistance and weather resistance and can be widely applied to natural gas pipelines.
