Question

Describe the important characteristics of low density polythene.

Answer 1

1. LDPE is a branched, low-crystallinity form of polythene with relatively low density.
2. It is soft and flexible, giving good impact resistance.
3. LDPE shows strong chemical resistance to many acids and solvents.
4. It has a low melting point, so it is easy to process and weld.
5. LDPE is electrically insulating and absorbs little water.
6. Common uses are films, bags, containers, and wire insulation.
