Question

What do you understand by low density polythenes?

Answer 1

1. Low density polythenes (LDPE) are polymers made from ethene; their chains are highly branched, so molecules cannot pack closely.
2. This branching gives LDPE a lower density, good flexibility, toughness, and fair transparency, so it is widely used for films, bags, and squeeze bottles.
3. LDPE softens at relatively low temperatures and resists many chemicals, making it useful for everyday plastic products.
