Product Description

Product Description

How is PE made?

Polyethylene is made from the polymerization of ethylene  monomer. The PE chains are produced by addition or radical polymerization. The possible synthesis methods are:
 

• Ziegler-Natta Polymerization and 
• Metallocene catalysis

What are the common types of PE?

Depending on its density and branching, different PE grades can have very different performance from one another.

PE grades are therefore classified as follows.
 

• 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)

Additionally, other types of PE are also available such as:
 

• Medium-density polyethylene (MDPE)
• Ultra low-density polyethylene (ULDPE)
• High-molecular-weight polyethylene (HMWPE)
• Metallocene polyethylene (mPE)
• Chlorinated polyethylene (CPE)

How to compare between the main PE types?

What is low density polyethylene (LDPE)?

Low-density Polyethylene (LDPE) is a semi-rigid polymer with low crystallinity (~50-60%). The LDPE is composed of 4,000-40,000 carbon atoms, with many short branches. Compared to HDPE, it has a higher degree of short and long side-chain branching. The chemical structure of LDPE is:
 

 

LDPE Structure

How is LDPE manufactured?

LDPE is produced at high pressure (1000-3000 bar) and temperature (80-300°C). It is derived via the free radical polymerization process.

Two basic processes to produce LDPE:
 

• Stirred autoclave reactor
• Tubular reactor

 

What are the properties of LDPE?

 

1. LDPE Melting point: 105 to 115°C
2. 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 weatherability
7. Excellent electrical insulating properties
8. Very low water absorption
9. FDA compliant
10. Transparent in thin film form
