Performance Properties of PP resins

Polypropylene (PP) has many properties and performances, including:

Chemical resistance: PP is resistant to many chemicals, including acids, bases, and organic solvents. It's only corroded by concentrated sulfuric acid and concentrated nitric acid.
Mechanical properties: PP is strong, tough, and has good impact resistance. It's also resistant to fatigue and heat.
Electrical properties: PP has good high-frequency insulation performance and a high dielectric constant. It's also suitable for use as electrical accessories.
Thermal properties: PP has a high melting temperature, making it suitable for use in high temperature applications. However, it can melt or deform at high temperatures.
Moisture barrier properties: PP has excellent moisture barrier properties, making it suitable for use in packaging applications.
Wear resistance: PP has good wear resistance.
UV resistance: PP is very sensitive to ultraviolet light.
Recyclability: PP is a highly recyclable material.
Biocompatibility: PP is generally considered biocompatible.
Odor: PP is generally odorless.

PP can be modified with additives for specific properties or applications
