Mo6-L2b: What are Ceramics and Plastics?
Advanced Ceramics are strong, hard, low Plastics are a synthetic material made from a wide
density, and very good thermal insulators. They are range of organic polymers, usually petroleum, that
used in space exploration because they can can be molded into shapes.
withstand intense high heat.
They are very common in all areas of our modern
life.
They have low densities with many different types
with different properties for different uses.

What are ceramics and their uses?
Nylon is strong, flexible, and transparent, and
waterproof. Rope, seat belts in cars, tents and other
products are made from nylon.
Acrylic is rigid, transparent, waterproof and has a
