Polyethylene
Facts about Polyethylene...
1. It has different types (grades), with density ranging from 0.857 g/cm3 to 0.975 g/cm3.
2. There are LLDPE, LDPE, HDPE.
2. The lower the density, the higher the impact strength of the part made from it.
3. The lower the density, the less the weight of part made from it.
4. Low density yields high toughness but low creep resistance.
5. Melt flow index (a function of processibility) is independent of density.
