Modification of secondary low density polyethylene (SLDPE) with shell-shaped limestone

Abstract

Low-density polyethylene has a good balance of flexibility, strength, barrier properties, and cost and can have a wide combination of properties. Low-density polyethylene has high clarity, is chemically inert, and has good impact strength and excellent tear and stress crack resistance. Low-density polyethylene (LDPE) has applications in sterile blister packs for drug packaging. Linear low-density polyethylene (LLDPE) is used in films and packaging due to its flexibility and toughness.

High-density polyethylene (HDPE) is typically translucent and less flexible than LDPE. Due to its higher crystallinity, it has better chemical resistance, stiffness, and strength than LDPE. Surgical and medical instruments use the vast majority of HDPEs. Like LDPE, HDPE exhibits good chemical and stress crack resistance, radiation resistance, and impact strength.
