Explanation:
1. Polyethylene terephthalate (PETE or PET):
PET is the most widely produced plastic in the world. It is used predominantly as a fiber (known by the trade name “polyester”) and for bottling or packaging. For example, PET is the plastic used for bottled water and is highly recyclable.

Three words or short phrases to describe the major benefits of Polyethylene relative to other plastics and materials would be:
Wide applications as a fiber (“polyester”)
Extremely effective moisture barrier
Shatterproof
2. Polyethylene (PE):
There are a number of different variants of polyethylene. Low and high density polyethylene (LDPE and HDPE respectively) are the two most common and the material properties vary across the different variants.

LDPE: LDPE is the plastic used for plastic bags in grocery stores. It has high ductility but low tensile strength.
HDPE: A stiff plastic used for more robust plastic packaging like laundry detergent containers as well as for construction applications or trash bins.
UHMW: Extremely strong plastic that can rival or even exceed steel in strength and is used is for applications like medical devices (e.g. artificial hips).
3. Polyvinyl Chloride (PVC):
Polyvinyl Chloride is perhaps most well known for its use in residential and commercial property construction applications. Different types of PVC are used for plumbing, insulation of electrical wires, and “vinyl” siding. In the construction business PVC pipe is often referred to by the term “schedule 40” which indicates the thickness of the pipe relative to its length.

Three words or short phrases to describe the major benefits of PVC relative to other plastics and materials would be:
Brittle
Rigid (although different PVC variants are actually designed to be very flexible)
Strong
4. Polypropylene (PP):
Polypropylene is used in a variety of applications to include packaging for consumer products, plastic parts for the automotive industry, special devices like living hinges, and textiles. It is semi-transparent, has a low-friction surface, doesn’t react well with liquids, is easily repaired from damage and has good electrical resistance (i.e. it is a good electrical insulator). Perhaps most importantly, polypropylene is adaptable to a variety of manufacturing techniques which makes it one of the most commonly produced and highly demanded plastics on the market.

Two short phrases to describe the major benefits of Polypropylene relative to other plastics and materials would be:
Unique Use For Living Hinges
Simple To Manufacture
5. Polystyrene (PS):
Polystyrene is used widely in packaging under the trade name “styrofoam.” It is also available as a naturally transparent solid commonly used for consumer products like soft drink lids or medical devices like test tubes or petri dishes.

One short phrase to describe the major benefits of Polystyrene relative to other plastics and materials would be:
Foam Applications
6. Polylactic Acid (PLA):
Polylactic Acid is unique in relation to the other plastics on this list in that it is derived from biomass rather than petroleum. Accordingly it biodegrades much quicker than traditional plastic materials.

Two words or short phrases to describe the major benefits of Polylactic Acid relative to other plastics and materials would be:
Biodegradable
