The melting point for average, commercial, low-density polyethylene is typically 105 to 115 °C (221 to 239 °F).

Polyethylene consists of nonpolar, saturated, high molecular weight hydrocarbons.

Polyethylene is a plastic. Chemical properties. Polyethene, Polythene, PE, LDPE, HDPE, MDPE, LLDPE. HDPE: 135°C (higher melting point compared to LDPE) LDPE: 115°C (Lower melting point compared to HDPE) Plastic resin codes. HDPE: HDPE is usually recycled, and resin identification code (also known as recycling symbol) is the number 2 (See figure 2). LDPE (Low Density Polyethylene) is defined by a density range of 0.910 - 0.940 g/cm 3.It has a high degree of short and long chain branching, which means that the chains do not pack into the crystal structure as well. Therefore, its chemical behavior is similar to paraffin.

The melting point of polyethylene varies from 85°C to 145°C, depending on the type of polymer. A.K.A. HDPE can have a melting temperature anywhere from about 120°C to 180°C, depending on grade, tacticity and molecular weight. Melting Point. The melting point for average, commercial, low density polyethylene is typically 105 to 115 °C (221 to 239 °F). These temperatures vary strongly with the type of polyethylene. Polyethene, which is another term for it, is a white and waxy polymer made up of only carbon and hydrogen. Most LDPE and HDPE grades have excellent chemical resistance and do not dissolve at room temperature because of their crystallinity. LDPE: LDPE has weaker intermolecular forces and tensile strength than HDPE. LDPE is an … LDPE is a thermoplastic that belongs to the polyolefin group of materials.
