WebApr 30, 2015 · Aging of HDPE increases the degree of crystallinity compared to non-aged material. The chain scission produces an overall decrease in tie molecules, allowing for lamellar reordering that results in an increase of the crystallinity of HA/HDPE composites. Glass fiber increases the percentage of crystallinity of LDPE, HDPE and MDPE …
