LyondellBasell’s low density polyethylene (LDPE) resins are thermoplastics made from the polymerization of ethylene in autoclave or tubular reactors at very high pressures. Unlike low-pressure polymerization technologies, high-pressure polymerization allows the co-polymerization of ethylene with polar comonomers, such as vinyl acetate or butyl acrylate. The polymer is characterized by a highly-branched polymer structure.
The ability to manufacture products on high-pressure autoclave and tubular reactors creates a very broad product portfolio for versatile film applications. Grades for use in extrusion coating, injection molding, blow molding, sheet and profile extrusion as well as other applications are also available.
Benefits and Applications
LDPE is used in a wide range of customer applications, including:
- Packaging film and bags for foodstuff and sanitary articles
- Agricultural film
- Surface protection film and lamination film
- Shrink and stretch hood film
- Bottles and tubes
- Healthcare applications
- Extrusion coating
- Lids, caps and closures
- Wire & cable
- Density < 0.935 g/cm³
- Superior flexibility
- Low melting point
- High melt strength in combination with relatively low melt viscosity
- Excellent processability
- Low gel levels
- Good transparency
