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