Low density polyethylene

Low density polyethylene (LDPE) is a type of PE with a density of 0.917 to 0.930 g/cm3, it can be translucid or opaque, it is flexible and resistant. It has the following applications:
  • Toys
  • Prlastic bags
  • Agricultural films
  • Plastic cutlery and plates
  • Bottles
  • Cable coating
  • Stretch film

Linear Low Density Polyethylene

LLDPE has shorter chains than LDPE, it is used in extrusion, blown plastic film, rotomolding, injection molding, film for freezed food, stretch film, cosmetic tubes, pharmaceutic applications, etc.

High Density Polyethylene

High Density Polyethylene (HDPE) is a polymer with a density of 0.93 to 0.97 g/cm3. It is stronger than LDPE, it can support higher temperatures in a short period of time.

Some of its applications are: Pipes for water distribution, detergent and other chemical containers, household goods.


Polypropylene Homopolymer is the most widely used PP. It is stronger and harder than copolymer, this toghether with its good chemical resistance and weldability allows this material to be used in many corrosion resistant structures.
  • Film
  • Raffia
  • Medical Products


It is softer but has a better impact streght, it is tougher and more durable than PPH. It normally has a better stress crack resistance and low temperature toughness than PPH.
  • Toys
  • Food Containers
  • Boxes
  • Ice Coolers


Polyethylene terephthalate (PET, PETE), is a plastic polymer, linear, with a high degree of crystallinity and thermoplastic in its behavior, which makes it suitable to be transformed through extrusion, injection, injection-blow and thermoforming processes. It is extremely hard, resistant to wear, dimensionally stable, resistant to chemicals and has good dielectric properties.
