This document summarizes three types of polymers - thermosetting polymers, thermoplastics, and elastomers. Thermosetting polymers retain their shape even when heated and are used to produce permanent components. Thermoplastics can be melted and reshaped but thermosettings cannot. Common applications of thermoplastics include food storage containers and plastic bags. Elastomers are polymers that are flexible and elastic. They are used to make products like shoe heels, wheels, and wetsuits.

1. Thermosetting, Thermoplastics
and Elastomers
By Olmo Vizan

2. Thermosetting
• Charcteristics:
• They retain strength and shape even when
heated
produce permanent components
solid shapes

3. • Properties:
• Exposies exhibit elasticity
chemical resistance
• Phenolics fairy simple to mold
but
brittle
strong and hard
relatively easy to
cure

4. Aplications:
It can be aplied for a/an electonic chip
fibre reinforced composite
polimeric coating
spectacle lenses
dental fillings

5. Thermoplastics
• Characteristics:
• It’s a type of plastic made from polymer resins
when heated homogenized liquid becomes
when cooled hard

6. • Properties:
• Are defined as; polymers that can be melted for different
uses.
Have the simplest molecular structure with
chemical independent macromolecules
• By heating are softened
or melted shaped welded
and solidified when cooled

7. • Aplications:
• For example Polycarbonate:
-compact discs -food storage containers
-drinking bottles -eyeglass lenses
Polyethylene
-shampoo bottles
-plastic grocery bags

8. Elastomers
• Characteristics:
• They have high elongation
flexibility
breaking against
• Clasified into:
• Thermoset Elastomers- not melt when heated.
• Thermoplastic Elastomers- they melt when
heated.

9. Elastomers part 2
• Properties:
• Cannot melt, before it pass gaseous
state
• Swell in presence certain solvents
• Are generally insoluble
• Are flexible and elastic
• Lower resistance than thermoplastic
materials

10. Elastomers part 3
• Aplications:
• It can be used for -Natural rubber; used to make shoe heels
-Polybutadiene; used on the wheels
-Neoprene; used to make wetsuits
-Silicone; used to make medical prostheses, lubricants,etc
