Polypropylene (PP) Polymers and Plastic Resins
Polymers and plastic resins are compounds comprised of repeating subunits of organic and synthetic base molecules. Several types of polymers and plastic resins exist today, and they are typically classified based on their chemical or polymer system type.
Polypropylene (PP) is a thermoplastic polymer that is formed via a chain-growth polymerization of propylene in the presence of Ziegler-Natta catalyst. Polypropylene polymers and plastic resins offer high resistance to corrosion and high tensile strength. These polymers also have good impact strength and fatigue resistance.
Polypropylene polymers are similar to polyethylene (PE) in terms of physical properties. However, PP offers higher rigidity and is more resistant to chemical solvents than polyethylene polymers. They are also able to withstand higher thermal conditions compared to polyethylene.
Key specifications
- Tensile strength: describes the maximum amount of stress required to break a PP polymer material under tension loading tests. It is expressed in pound per square inch (psi).
- Thermal conductivity: describes the ability of the PP polymer and plastic resin to conduct heat. It is defined as the rate at which heat can be conducted through a unit cross-section area of the polypropylene polymer.
- Use temperature: describes the range of temperatures that the polypropylene polymer can be exposed to without degradation of its properties.
- Coefficient of thermal expansion: describes the fractional change in the size of a PP polymer material per degree change in temperature at a constant pressure.
- Additional features: options include anti-static, flame retardant, and EMI shielding polypropylene polymers and plastic resins. Polypropylene polymers with anti-static additives can reduce the buildup of static electricity. In contrast, those with flame retardant additives can withstand high temperatures and resist ignition.
Applications
Polypropylene polymer is a staple in many industries due to its desirable properties. For example, its high tensile strength makes it suitable in applications involving heavy loads and rugged use. Also, its high resistance to corrosion makes it suitable for manufacturing piping systems. Polypropylene polymers and plastic resins are also used to make water-proof roofs and laboratory containers.
