Polyethylene is a lightweight, durable thermoplastic with a variable crystalline structure. It is one of the most widely produced plastics in the world (tens of millions of tons are produced worldwide each year). Polyethylene is used in applications ranging from films, tubes, plastic parts, laminates, etc. in several markets (packaging, automotive, electrical, etc.). Polyethylene is made from the polymerization of ethylene monomers as we are the Polyethylene Film Manufacturers.

Common Types of Polyethylene (PE)

PE belongs to the polyolefin family of polymers and is classified by its density and branching. The most common types of polyethylene areas we have the best high-density polyethylene in Dubai:

  • Branched Versions
    • Low-density polyethylene (LDPE)
    • Linear low-density polyethylene (LLDPE)
  • Linear Versions
    • High-density polyethylene (HDPE)
    • Ultra-high-molecular-weight polyethylene (UHMWPE)
  • Cross-linked polyethylene (PEX or XLPE)

In addition, PE is also available in other types such as (not discussed in detail in this guide)

  • Medium-density polyethylene (MDPE)
  • Very-low-density polyethylene (VLDPE)
  • High-molecular-weight polyethylene (HMWPE)
  • Ultra-low-molecular-weight polyethylene (ULMWPE)
  • Chlorinated polyethylene (CPE)
High-Density Polyethylene (HDPE)

High-Density Polyethylene (HDPE) is a cost-effective thermoplastic with a linear structure and no or low degree of branching. It is manufactured at low temperature (70-300°C) and pressure (10-80 bar) & derived from either:

  • Modifying natural gas (a methane, ethane, propane mix) or
  • The catalytic cracking of crude oil into gasoline

HDPE is produced majorly using two techniques: Slurry Polymerization or Gas Phase Polymerization this is the best polyethylene product in UAE.

Properties of High-Density Polyethylene
    1. HDPE Melting point: 120-140°C
    2. Density of HDPE: 0.93 to 0.97 g/cm3
    3. High-Density Polyethylene Chemical resistance:
      • Excellent resistance to most solvents
      • Very good resistance to alcohols, dilute acids, and alkalis
      • Moderate resistance to oils and greases
      • Poor resistance to hydrocarbons (aliphatic, aromatic, halogenate
    4. Continuous temperature: -50°C to +60°C, Relatively stiff material with useful temperature capabilities
    5. Higher tensile strength compared to other forms of polyethylene
    6. Low-cost polymer with good processability
    7. Good low-temperature resistance
    8. Excellent electrical insulating properties
    9. Very low water absorption
Applications of High-Density Polyethylene (HDPE)

An excellent combination of properties makes HDPE an ideal material in diverse applications across industries. It can be engineered according to the end-use requirements.

    1. Packaging Applications – High-Density Polyethylene is used in several packaging applications including crates, trays, bottles for milk and fruit juices, caps for food packaging, jerry cans, drums, industrial bulk containers, etc. In such applications, HDPE provides the end product a reasonable impact strength.
    2. Consumer Goods – Low cost and easy processability make HDPE material of choice in several household/ consumer goods like garbage containers, housewares, ice boxes, toys, etc.
    3. Fibers and Textiles – Thanks to its high tensile strength, HDPE is widely used in ropes, fishing and sports nets, nets for agricultural use, Industrial and decorative fabrics, etc
Low-Density Polyethylene (LDPE)

Low-Density Polyethylene (LDPE) is a semi-rigid and translucent polymer. Compared to HDPE, it has a higher degree of short and long side-chain branching. It is produced at high pressure (1000-3000 bar; 80-300°C) via the free radical polymerization process.

The LDPE is composed of 4,000-40,000 carbon atoms, with many short branches.

Two basic processes used for the production of low-density polyethylene: stirred autoclave or tubular routes. The tubular reactor has been gaining preference over the autoclave route due to its higher ethylene conversion rates as we are the polyethylene Film Manufacturers.

Properties of Low-Density Polyethylene

    1. LDPE Melting point: 105 to 115°C
    2. The density of LDPE: 0.910–0.940 g/cm3
    3. Chemical resistance of LDPE:
      • Good resistance to alcohols, dilute alkalis, and acids
      • Limited resistance to aliphatic and aromatic hydrocarbons, mineral oils, oxidizing agents, and halogenated hydrocarbons
    4. Temperature resistance up to 80°C continuously and 95°C for shorter times.
    5. Low-cost polymer with good processability
    6. High impact strength at low temperature, good weather ability
    7. Excellent electrical insulating properties
    8. Very low water absorption
    9. FDA compliant
    10. Transparent in thin-film form
Applications of Low-Density Polyethylene (LDPE)

Low-Density Polyethylene (LDPE) uses majorly revolve around manufacturing containers, dispensing bottles, wash bottles, tubing, plastic bags for computer components, and various molded laboratory equipment. The most popular application of low-density polyethylene is plastic bags as we are the best film manufacturers in UAE.

    1. Packaging – Thanks to its low cost and good flexibility, LDPE is used in the packaging industry for pharmaceutical and squeeze bottles, caps, and closures, tamper-evident, liners, trash bags, films for food packaging (frozen, dry goods, etc.), laminations, etc.
    2. Pipes and Fittings – Low-Density Polyethylene is used to manufacture water pipes and hoses for the pipes and fittings industry due to Its plasticity and low water absorption.

Other applications include consumer goods – housewares, flexible toys, agricultural films, wiring & cables – sub-conductor insulators, cable jacketing.

Linear Low-Density Polyethylene (LLDPE)

LLDPE is produced by polymerization of ethylene (or ethane monomer) with 1-butene and smaller amounts of 1-hexene and 1-octene, using Ziegler-Natta or metallocene catalysts. It is structurally similar to LDPE.

The structure of LLDPE has a linear backbone with short, uniform branches (unlike longer branches of LDPE). These short branches are able to slide against each other upon elongation without becoming entangled like LPDE.

In the present day scenario, Linear low-density polyethylene (LLDPE) has been quite successful in replacing Low-Density Polyethylene.

Properties of LLDPE

  • Very flexible with high impact strength
  • The translucent and natural milky color
  • Excellent for mild and strong buffers, good chemical resistance
  • Good water vapor and alcohol barrier properties
  • Good stress crack and impact resistance

Applications of LLDPE: Suitable for a variety of film applications such as general-purpose film, stretch film, garment packaging, agricultural film, etc.

Benefits of Polyethylene Films
  • PE films burn to carbon dioxide and water with no residue. There are no toxic fumes or gases and no cinders produced in this process
  • PE films contain no plasticizers and no heavy metals. They are physiologically harmless
  • No odor pollution or wastewater are produced in the manufacture of PE films
