One of the important family of polyolefin resins, polypropylene is molded or extruded into many plastic products in which toughness, flexibility, light weight, and heat resistance are required.
Polypropylene is a versatile plastic used in items like toys, carpets, and food containers
Polypropylene is heat resistant and doesn't easily absorb water, making it great for microwaves and outdoors Polypropylene is a type of thermoplastic polymer resin. What does the abbreviation pp stand for Pp materials are universally standard plastics with well balanced properties that provide excellent chemical resistance, high purity, low water absorption and good electrical insulating properties
In addition, polypropylene material is lightweight, conductive and weldable. Polypropylene (pp) is a thermoplastic linear hydrocarbon polymer resin that is a bit rigid and resistant to chemicals and electricity at high temperatures Since pp is a thermoplastic, it can be soft at high temperatures and hardens at low temperatures.
