PP and HDPE
- HDPE has higher tensile strength and intermolecular force than LDPE. This strength is due to its little branching at the molecular level.
- It has increased specific strength because the density difference is outweighed by the density difference.
- This is very difficult and opaque.
- It can withstand high temperatures up to 110 degrees Celsius continuously and up to 120 degrees Celsius for shorter periods of time.
- It cannot withstand autoclaving conditions.
- HDPE is resistant to many solvents.
Summary of Difference Between PP and HDPE
- "PP" stands for "polypropylene" and "polypropylene"; "HDPE" stands for "high-density polyethylene".
- Made of propylene; HDPE is made of petroleum.
- The crystallinity of PP is lower than that of HDPE.
- The melting range of PP is 160-166 degrees Celsius; HDPE can withstand temperatures up to 120 degrees Celsius.
- The molding and extrusion methods are used together with blow molding. HDPE is manufactured by polymerization, and comonomers are added to reduce branching.
- THEY HAVE VARIOUS APPLICATIONS.
