    What''s the difference between LDPE and HDPE? | …

    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.
