What is medium density polyethylene?
Properties and Benefits
Medium density polyethylene is produced by blending LDPE and HDPE, thus combining the properties of both. MDPE (Medium Density Polyethylene) is characterized by a matte surface, high strength, and a slight crackling sound. MDPE is softer and stiffer than LDPE. It is more flexible than HDPE and has high scratch resistance. Further advantages include good impact and drop resistance, as well as better cutting performance than HDPE. It is therefore suitable for use in harsh environments. It meets food handling guidelines. The material is fully recyclable and can be reused. Its stress crack resistance is comparable to that of HDPE.
What is the density of medium density polyethylene?
Between 0.926 – 0.940 g / cm3
Medium density polyethylene has a density between 0.926 – 0.940 g / cm3. It has very good resistance to shock and it is also much less sensitive than HDPE, having a very good resistance to cracking and breakage.
Medium-Density Polyethylene Uses
MDPE can be processed via extrusion, injection molding, blow molding, rotational molding, powder molding, and other methods. Its production parameters are similar to those of HDPE and LDPE. It is commonly used for pipes, films, hollow containers, and other products. Applications include high-speed molding of various bottles, high-speed automatic packaging films, various injection-molded products, rotational-molded items, wire and cable sheathing, waterproofing materials, water pipes, gas pipes, and more.
