PE (Polyethylene)

PE is belong to polyolefin family and semi-crystaline thermoplastic polymer. PE is divided to 3 main category; Lineer low density (LLDPE), Low density (LDPE) and high density.
 
Lineer Low density polyethylene ( LLDPE)
LLDPE has widely usage application due to high performance, easy processing, blown and cast film, multilayer production, ekstrusion coating, injection molding, pipe and rotation moulding. In addition to these applications, it's also used for hot and cold water piping, underfloor heating pipes (PE-RT), membrans and other durable consumer goods. 
 
Characteristic Properties;
•  Tensile strenght
•  Puncture resistance,
•  Dart drop strenght 
•  Tear resistance  
•  Easy processing 
•  Lightweight material, reducing weight.
•  Good hot sealing property
•  Glossy appearance
 
 
Application;
 
Extrusion blown film  cast and stretch film, frozen food films, hygien films.
 
Low density Polyethylene (LDPE)
LDPE, is a syntetic polymer , produced with etyhlene monomer polymerization. It's one of mostly used plastic product in human life. It has perfect properties like easy processing, tranparent, flexible, glossy. So that it's widely used a plastic in the World.
 
Characteristics,
 
• Perfect flexibility
• Printable
• Tensile strenght
• Tear resistance
•  Elasticity
 
  Applications;
 
Complex food packaging, multilayer film, shopping bags, garbage bags, various packaging films, consumer pochets, heavy duty bags, lamination films, agriculturel films, extrusion coationg, coated papers, injection molding, caps & closures, toys, compound production, toys and other consumer goods. 
 
High density polyethylene (HDPE)
HDPE has a very good wearing and impact property, having lower friction. It's also good against humidity, odor and stain Thanks to it's individual properties; it's used for many application in human life like ; cap&closure, water tanks, bottles for beverage and food.HDPE has a very high stiffnes and tensile strength comparing Low and lineer low PE types. It's properties is also very good under lower temperatures than most of the other plastic polymers. 
 
Characteristics;
 
• High molecular weight
• Low shrinkage, good dimensional stability
• High mechanical strenght
• Easy processing
• Good stifness
 
Application;
 
Pipe extrsion, shopping bags, toys, cosmetic packaging, plastic bottles,home care products, stationary , detergant packaging, plastic pallets & crates, car batteries and indutrial parts for outdoor usage.
