1.A) ThermoplasticsThermoplastics are low of cost, are able to be colored, have good wear resistance, cold and heat resistance, as well as weathering resistance CD cases are known for being made out of a thermoplastic material. CD cases are flexible but strong enough to keep a CD safe. CD cases contain Polypropylene.B)Thermoset productsBetter retention of mechanical properties at high temperatures. They have higher toughness and impact resistance. And better environmental resistanceSource: ENTC 206 notes
A police anti rioting shield is a thermoset product. These are used the shield off people with their high level of strength. They contain Polycarbonate. C)Elastomer productElastomers are a natural or synthetic polymer having elastic properties. An example would be rubber.
