These comprehensive RBSE Class 8 Science Notes Chapter 3 Synthetic Fibres and Plastics will give a brief overview of all the concepts.

RBSE Class 8 Science Chapter 3 Notes Synthetic Fibres and Plastics

→ Synthetic fibres are made by man therefore, they are also called synthetic fibres or man made fibres. These are prepared by polymerisation process.

→ Synthetic fibres are used in ropes, buckets, furniture, containers, aeroplanes, ships, space crafts and healthcare.

→ On the basis of chemicals used in the commercial production of synthetic fibres, they are named as Rayon, Nylon, Polyester and Acrylic.

→ Plastic, ‘which gets deformed on heating is called thermoplastic and which can not be deformed on heating are called thermosetting plastic.

→ Plastic causes environmental pollution so it should be used with the consideration of 5R theory (Reduce, Reuse, Recycle, Recover and Refuse).
