POLYMERS TRADING

Trough our vast network of connections and collaborations, we are able to source and supply our customers with different types of Polymers, such as:

 

- LDPE

- HDPE

- LLDPE 

- MDPE

LDPE (Low Density Polyethylene)

Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene. LDPE is defined by a density range of 0.910–0.940 g/cm3. It is not reactive at room temperatures, except by strong oxidizing agents, and some solvents cause swelling. It can withstand temperatures of 80 °C continuously and 95 °C for a short time. Made in translucent or opaque variations, it is quite flexible and tough.

HDPE (High Density Polyethylene)

High-density polyethylene (HDPE) is known for its large density to strength ratio.

 

The density of HDPE can range from 0.93 to 0.97 g/cm3 or 970 kg/m3. Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength than LDPE.

 

The difference in strength exceeds the difference in density, giving HDPE a higher specific strength. It is also harder and more opaque and can withstand somewhat higher temperatures (120 °C/ 248 °F for short periods).

 

HDPE is resistant to many different solvents and has a wide variety of applications.

LLDPE (Linear Low Density Polyethylene)

Linear low-density polyethylene (LLDPE) has higher tensile strength and higher impact and puncture resistance than does LDPE.

 

It is very flexible and elongates under stress.

It can be used to make thinner films, with better environmental stress cracking resistance. It has good resistance to chemicals. It has good electrical properties. However, it is not as easy to process as LDPE, has lower gloss, and narrower range for heat sealing.

 

LLDPE has penetrated almost all traditional markets for polyethylene; it is used for plastic bags and sheets (where it allows using lower thickness than comparable LDPE), plastic wrap, stretch wrap, pouches, toys, covers, lids, pipes, buckets and containers, covering of cables, geo membranes, and mainly flexible tubing.
