The MDPE – medium density polyethylene obtained as a physical mixture of HDPE and LDPE, is defined by a density range of 0.926–0.940 g/cm3. MDPE can be produced by Ziegler-Natta catalysts or metallocene catalyst and their properties vary.
Medium Density Polyethylene (MDPE) Properties
MDPE is extremely resistant to impact and flow and can be easily used in many areas with these characteristics. Compared with HDPE, it seems to be more resistant to cracking and crenation under stress. MDPE is characterized by its high stress cracking resistance and long-term hold resistance. MDPE, with a tensile strength of 8 to 24 MPa, has an elongation at break of at least 50% and 60%. The range of melting temperature varies between 126 °C and 135 °C.
Advantages of Medium Density Polyethylene (MDPE) and Uses
Medium Density Polyethylene (MDPE), which is inexpensive in terms of costs and offers many advantages in terms of its properties, can be easily used in many areas. Medium Density Polyethylene, resistant to outdoor conditions and moisture, has a flexible structure due to its superior chemical resistance and can be used extensively in the market. The main uses of Medium Density Polyethylene (MDPE) can be listed as follows:
- Gas Pipes
- Fittings
- Shrink film
- Bags
- Cases
- Packaging film
- Blow molding and injection areas
- Rotational coating
- Automatic packaging films
