Difference between Polypropylene and Polystyrene

Polypropylene vs. Polystyrene

Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. Polystyrene (PS) is a synthetic aromatic hydrocarbon polymer made from the monomer styrene.

Acrylonitrile butadiene styrene

Acrylonitrile butadiene styrene (ABS) (chemical formula (C8H8)x·(C4H6)y·(C3H3N)z) is a common thermoplastic polymer.

Glass transition

The glass–liquid transition, or glass transition, is the gradual and reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials), from a hard and relatively brittle "glassy" state into a viscous or rubbery state as the temperature is increased.

Polyethylene terephthalate

Polyethylene terephthalate (sometimes written poly(ethylene terephthalate)), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P, is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fibre for engineering resins.

Tacticity

Tacticity (from Greek τακτικός taktikos "of or relating to arrangement or order") is the relative stereochemistry of adjacent chiral centers within a macromolecule.

Thermoplastic

A thermoplastic, or thermosoftening plastic, is a plastic material, a polymer, that becomes pliable or moldable above a specific temperature and solidifies upon cooling.

Transparency and translucency

In the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without being scattered.
