lignin hdpe composites usa

Unmodified and esterified Kraft lignin‐filled polyethylene .

KL and ML were respectively incorporated into high density polyethylene HDPE up to 60% wt and dicumyl peroxide was used as a free‐radical generator. The influence of lignin esterifi ion and free‐radical grafting on the morphological mechanical and thermal properties of lignin‐based composites was studied.
