Abstract: The classification, ignition principles, of nonel tube as well as its foreign and domestic production and application were introduced. Two domestic PE-LD-based nonel tubes, trademark 1I2A and 18D0, were compared. Although the general properties (MFR and Density) of the two nonel tubes were similar, the gunpowder adhesion of 1I2A was better. This was attributed to the difference in the thermal stability and crystallization behavior of the materials.

Key words: nonel tube, low density polyethlene, crystal property
