POLYMER TYPES

Polyethylene (PE): Types and Applications

Günlük hayatta en yaygın kullanılan termoplastiklerden biri olan polietilen; yoğunluğuna ve moleküler yapısına göre HDPE, LDPE ve LLDPE gibi farklı sınıflara ayrılır. Uygulamanıza uygun PE türünü seçmek için teknik özellikleri ve kullanım alanlarını inceleyin.

PE PRODUCT GROUPS

Polyethylene Types by Application

The core difference between polyethylene types is density and chain structure; this directly affects properties such as stiffness, flexibility, chemical resistance and processability.

HDPE

Thanks to its linear chain structure, high-density polyethylene offers high stiffness, strength and chemical resistance.

  • Water and natural gas pipes
  • Bottle and drum production
  • Packaging caps and boxes

LDPE

Low-density polyethylene, with its branched chain structure, is soft, flexible and close to transparent.

  • Packaging film and bags
  • Agricultural covers
  • Cable insulation

LLDPE

Linear low-density polyethylene provides higher impact and puncture resistance than LDPE.

  • Stretch film
  • Industrial packaging
  • Flexible pipes and hoses

TECHNICAL PROPERTIES

Key Properties of Polyethylene

PE type selection should be based on mechanical strength, chemical resistance, processability and cost balance.

01

Chemical Resistance

Shows high resistance to acids, bases and many solvents, making it suitable for chemical packaging.

02

Low Density

Its light weight is an advantage in transport and logistics costs.

03

Processability

Adapts easily to processes such as injection, extrusion and blow molding.

04

Water Resistance

Thanks to its high resistance to moisture and water, it is preferred in packaging and insulation applications.

APPLICATIONS

Where Is Polyethylene Used?

PE is preferred across many industries because it offers a wide range of density and mechanical properties.

  • Pipe and profile systems (infrastructure, drinking water, natural gas)
  • Packaging and film applications
  • Bottle, drum and industrial container production
  • Cable insulation and sheathing
  • Agricultural covers and irrigation systems
Choosing the Right PE Type

When choosing the PE type for your application, consider the operating environment, mechanical load, temperature conditions and production process together. Contact our team for suitable products and sourcing options.

FREQUENTLY ASKED QUESTIONS

About Polyethylene

What is the difference between HDPE and LDPE?

HDPE is stiff and durable thanks to its denser, linear structure, while LDPE is more flexible and soft because of its branched structure.

What temperature range can polyethylene be used in?

Service temperature varies by type and grade; for applications requiring high temperatures, always review the technical data sheet.

Why is LLDPE preferred for stretch film?

LLDPE’s high puncture and impact resistance makes it possible to obtain strong film even at thin gauges.

Do PE prices vary by type?

Yes, HDPE, LDPE and LLDPE prices may differ by grade, production process, origin and market conditions. You can request a quote for current pricing.
