Linear ,Low,-density ,Polyethylene, Linear ,low,-density ,polyethylene, (LLDPE) is widely used not only in processing but also in daily life. Produced by a ,low,-,pressure, polymerization process, LLDPE has a linear polymer chain and short chain branch structure.

Polyethylene: LDPE
Polyethylene: LDPE

Low, density ,polyethylene, (LDPE) is the oldest form of ,polyethylene, and is produced under high ,pressure, conditions which promote the formation of a high degree of both long and short chain branching within the polymer structure. These ,characteristics, give rise to resins which are soft, tough and flexible, as well as being easy to process.

HDPE,: Shrinkage Because ,HDPE, is a crystalline material, the shrinkage is high: about 0.015 – 0.04mm/mm or 1.5 – 4%. This will depend on the degree of orientation and the level of crystallinity in the part – and that, of course, depends on the processing conditions and even the design of the part that you’re manufacturing.
