Defense responses in earthworms (Eisenia fetida) exposed to low-density polyethylene microplastics in soils.

Ecotoxicology and Environmental Safety, 2020
The potential threats of microplastics to global health are a new problem. However, little is known about the influence of microplastics on soil organisms.

Biodegradation of low-density polyethylene and polystyrene in superworms, larvae of Zophobas atratus (Coleoptera: Tenebrionidae): Broad and limited extent depolymerization.

Environmental Pollution, 2020
Larvae of Zophobas atratus (synonym as Z. morio, or Z. rugipes Kirsch, Coleoptera: Tenebrionidae) are capable of eating foams of expanded polystyrene (EPS) and low-density polyethylene (LDPE), similar to larvae of Tenebrio molitor.

Low density polyethylene – Chitosan composites

Composites Part B: Engineering, 2013
Abstract With the aim of develop new materials for active food packaging, composites of low-density polyethylene (LDPE) with chitosan (CS) or chitosan sodium montmorillonite clay nanocomposites (CSnano), with or without Irganox 1076 commercial synthetic antioxidant or vitamin E (VE) as natural antioxidant were prepared by melt processing.

Melt strength of linear low‐density polyethylene/low‐density polyethylene blends

Journal of Applied Polymer Science, 2002
AbstractLinear low‐density polyethylenes and low‐density polyethylenes of various compositions were melt‐blended with a batch mixer. The blends were characterized by their melt strengths and other rheological properties. A simple method for measuring melt strength is presented.

Thermo-mechanical degradation of polypropylene (PP) and low-density polyethylene (LDPE) blends exposed to simulated recycling

Polymer degradation and stability, 2020
Polypropylene (PP) and low-density polyethylene (LDPE) are among the most converted resins; as such, they also have the largest share in municipal waste fractions.

Crystallization of low-density polyethylene- and linear low-density polyethylene-rich blends

Journal of Applied Polymer Science, 2000
The crystallization of a series of low-density polyethylene (LDPE)- and linear low-density polyethylene (LLDPE)-rich blends was examined using differential scanning calorimetry (DSC). DSC analysis after continuous slow cooling showed a broadening of the LLDPE melt peak and subsequent increase in the area of a second lower-temperature peak with ...

Recycled plastic as bitumen modifier: The role of recycled linear low-density polyethylene in the modification of physical, chemical and rheological properties of bitumen

, 2020
The integration of various polymers in bitumen is common practice to reduce its thermal susceptibility. Nowadays, recycled materials are re-purposed in roads to improve the overall pavement performance and durability.

Modification of recycled high‐density polyethylene by low‐density and linear‐low‐density polyethylenes

Polymer Engineering & Science, 2003
AbstractThe present study investigated mixed polyolefin compositions with the major component being a post‐consumer, milk bottle grade high‐density polyethylene (HDPE) for use in large‐scale injection moldings. Both rheological and mechanical properties of the developed blends are benchmarked against those shown by a currently used HDPE injection ...
