POLYTHELENE (PE)

Polythene (PE) is chemically the simplest polymer. The types of polythenes that we handled are:

PEBD Typical: Low density. Nontoxic. Flexible. Light. It is transparent. Raincoat. Low cost.

Applications:

  • Bags of all type, congealed,industrial supermarkets, boutiques, baking, etc.
  • Films for land.
  • Envasin automatic packaging,foods and industrial products: milk, water, plastics, etc.
  • Stretch film.

HDPE High Density Polythene ; density equal or smaller to 0,941 g/cm3. It has a low level of ramifications, thus his density is high, the intermolecular forces are high also.

HDPE Typical: Resistant to the low temperatures; High resistance to the tension; compression, traction; Low density in comparison with metals or other materials; -Raincoat; Nontoxic; Little dimensional stability, creep.

Aplicaciones

  • Packages for: detergents, lye, oils automotive, shampoo, milky.
  • Bags for supermarkets.
  • Drawers for fish, soda waters, beers.
  • Packages for painting, ice creams, oils.

Polythene is used for different types from end items, for each of them are also used different processes, between most common are:

  • Extrusion: Film, cables, threads, pipes.
  • Moulding by injection: Parts in third dimension with complicated forms
  • Blown injection and: Bottles of different sizes
  • Blown extrusion and: Bags or tubes of thin caliber
  • Blown extrusion and of hollow bodies: Bottles of different sizes.

Polythene has a translucent milky color; this color can be modified with three common procedures:

  • To color all the PE before its processing
  • To use a color concentrate (well-known in English like masterbatch), which represents the form economic and easy to color a polymer.
