What monomers make up polypropylene?
Polypropylene is a tough, rigid and crystalline thermoplastic produced from propene (or propylene) monomer. It is a linear hydrocarbon resin. The chemical formula of polypropylene is (C3H6)n. PP is among the cheapest plastics available today.
What are the properties of PP?
The properties of Polypropylene include…
- Semi-rigid.
- Translucent.
- Good chemical resistance.
- Tough.
- Good fatigue resistance.
- Integral hinge property.
- Good heat resistance.
What polypropylene is used for?
Polypropylene (PP) is one of the most commonly used thermoplastics in the world. Polypropylene uses range from plastic packaging, plastic parts for machinery and equipment and even fibres and textiles.
Is polypropylene a PP?
Polypropylene (PP) is a thermoplastic “addition polymer” made from the combination of propylene monomers. It is used in a variety of applications to include packaging for consumer products, plastic parts for various industries including the automotive industry, special devices like living hinges, and textiles.
What is the monomer of PVC?
PVC is produced from its monomer, vinyl chloride. PVC is a hard plastic that is made softer and more flexible by the addition of plasticizers, the most widely used being phthalates.
What is PP and PE plastic?
Polyethylene is a polymer made of ethylene, and depending on how it polymerises, the properties of polyethylene change. Polypropylene, however, is classified as number 5 – PP. It is also a plastic polymer, but its monomer is propylene, which is easily produced and has a high degree of purity.
Is polypropylene the same as plastic?
Polypropylene is an example of a plastic polymer. The key difference between polypropylene and plastic is that we can produce crystal clear material from polypropylene, whereas plastic material is not usually clear. The important properties of polypropylene include lightweight, low toxicity, high melting point, etc.
Which is stronger polyethylene or polypropylene?
Polypropylene is not as sturdy as polyethylene. Polypropylene is stiffer and resistant to chemicals and organic solvents compared to polyethylene. Polypropylene is pure, non-stretching and generally more rigid than polyethylene.
