HDPE – high density polyethylene (HDPE) looks very similar to the LDPE (low density polyethylene), but this polymer type is rougher than LDPE. It is produced by polymerizing the ethylene monomers at low pressure.
High Density Polyethylene (HDPE) Properties
Although it is highly resistant to the chemical substances and water, High Density Polyethylene (HDPE) isn’t weatherproof and light resisting. However, it is also sensitive against the nitric acid. While the melting flow rate of High Density Polyethylene (HDPE) is between 0,02 and 20, its density ratio is greater than 0,940 g/cm3 and its melting temperature varies between 125 and 135 degrees. Since it can be joined with the welding method and can be supplied in larger sizes, this material can be easily used in the production of the tank and the treatment of wastewater.
The degree of branching is very low and HDPE is suitable for the injection. Finally, its molecular structure is linear. Accordingly, the molecules can be effortlessly combined. In other words, the molecules that can be collected at a lower volume generate a material that provides a high value in terms of density and roughness.
Where to Use High Density Polyethylene (HDPE)?
HDPE, which is widely used in many areas, is mainly used in the following areas:
- Motor oil containers
- Detergent bottles
- Shopping bag
- Bag
- Plastic bag
- Jerrycan
- Bottle
- Jar
- Toys
- Lids
- Safes
- Kitchenware
