what are the three of the most important plastics indicates in the manufacture
Answers
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
