Exploring the World of Thermo Plastics

Exploring the World of Thermo Plastics

Learning Objective

Understand the properties and applications of thermo plastics in engineering.

What do you already know about thermo plastics?

What is a key characteristic of thermoplastics?

1. They can be melted and reformed
2. They retain their shape permanently

Introduction to Thermo Plastics

Thermo plastics are a type of polymer that become pliable or moldable when heated and harden upon cooling.

Properties of Thermo Plastics

Thermo plastics have high strength, impact resistance, and are recyclable. They can be shaped numerous times without damage.

Applications of Thermo Plastics

Thermo plastics are used in manufacturing automotive parts, medical devices, packaging, and consumer goods.

Manufacturing Process

The manufacturing process of thermo plastics involves heating the material to a pliable state, shaping it, and then cooling it to form the desired product.

Comparison with Thermosetting Plastics

Thermo plastics can be reshaped and recycled, whereas thermosetting plastics are set in a permanent form and cannot be reshaped or recycled.

Environmental Impact

Thermo plastics are recyclable, contributing to sustainability efforts and reducing environmental impact compared to other materials.

Interactive Activity

Hands-on activity: Students will examine various objects made of thermo plastics and identify their properties and potential applications.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
