Custom Polyethylene (HDPE, MDPE & LDPE) Extrusion

Custom Polyethylene (HDPE, MDPE & LDPE) Extrusion

Polyethylene is one of the most common plastics in use today. A thermoplastic polymer, polyethylene is available in different polymers grouped by the molecular weight, or density.

Preferred Plastics extrudes high quality custom plastic parts using polyethylene.  A leading custom extruder, Preferred Plastics offers an inventory of standard compounds of polyethylene, including HDPE, MDPE, and LDPE.

Polyethylene is one of the most common plastics in use today. A thermoplastic polymer, polyethylene is available in different polymers grouped by the molecular weight, or density.

  • HDPE – High density polyethylene is defined by a density greater than or equal to 0.941 g/m3. It is manufactured from petroleum and has a low degree of chain branching, resulting in strong intermolecular forces. HDPE has a high strength-to-density ratio, is corrosion and chemical resistant, and weatherproof.
  • MDPE – Medium density polyethylene is defined by a density range of 0.926 – 0.940 g/m3.  MDPE is produced by chromium/silica catalysts. MDPE exhibits good shock and drop resistance properties, with better stress.
  • LDPE – Low density polyethylene is defined by a density range of 0.910 – 0940 g/m3. It is comprised of long and short chain branching, which results in weaker intermolecular forces than MDPE. It manufactured by free radical polymerization from the monomer ethylene. LDPE is more flexible than MDPE, strong, weatherproof, and chemical resistant. 

Overall, polyethylene is a low cost, easy-to-process material. Some grades of polyethylene are recyclable.
