Abstract

Blends of recycled LDPE and LLDPE were prepared by the twin-screw extruder at different ratios. Recycled LDPE was used as matrix in this work, LLDPE was used to improve the properties of RLDPE. Virgin LDPE was used in this study as a contrast. Rheological properties of the blends were carefully evaluated by a Haake rheometer and compared with pure LDPE. Rheological analysis shows that virgin LLDPE will promote the normal flow of RLDPE in the a large content and hinder the mobility of chain segments when in a small content of LLDPE. Consequently, the blends show potential applications in high-value products.
