LDPE – low density polyethylene , one of the thermoplastic types, is a type of polymer. There are two types of polyethylene; low and high density polyethylene. One of these types, Low Density Polyethylene (LDPE) is formed with the polymerization method at the high pressure.
Low Density Polyethylene (LDPE) and Properties
With a low density, Low Density Polyethylene (LDPE) has a superior tensile strength and tear resistance with a density between 0,910 g / cm3 – 0,930 g / cm3. The impact resistance is extremely high and the films made with LDPE have superior optical characteristics and they are slippery. The hoses produced with Low Density Polyethylene (LDPE) are resistant and the process of cable insulation is highly resistant to cracking. I can be easily colored. When the melting flow rate is in the range of 0.2 to 50, the melting temperature ranges from 100 °C to 120 °C. Especially used in the agriculture, LDPE was first used in Turkey in 1970. It is unresponsive to room temperature except for high oxidation factors. It has a strong structure as it never breaks.
Uses of Low Density Polyethylene (LDPE)
With its particular characteristics, LDPE can be used in many areas, particularly in the agriculture. Other than that, we can list the uses of Low Density Polyethylene (LDPE) as follows:
- Shopping bag
- Bubble wrap
- Strech
- Salt – sugar – chicken bag
- Grocery – market bag
- Closure caps
- Toys
- Films (Greenhouse covers, bag, sack)
- Household – kitchenware
