1. Density: The density of ordinary polyethylene is generally between 0.92 and 0.96 g/cm³, while the density of ULDPE is even lower, generally between 0.88 and 0.92 g/cm³. Its extremely low density is one of its most significant characteristics.
2. Mechanical Properties: ULDPE possesses excellent mechanical properties such as good flexibility, high toughness, impact resistance, and tensile strength.
3. Chemical Stability: ULDPE exhibits a certain degree of resistance to some chemical substances, such as weak corrosive substances like acids and alkalis, oxidizing agents, and some solvents.
4. Thermal Properties: The melting point of ULDPE is generally between 110 and 130℃, demonstrating good thermal stability and allowing for use within a certain temperature range.
