Reinforcing high-density polyethylene by phenolic spheres

open access: yesMATEC Web of Conferences, 2018
Phenolic spheres are synthesized through resorcinol and formaldehyde. The phenolic spheres were blended with HDPE to prepare binary composites. The rheological properties and mechanical properties of the composites were studied.

FRICTION AND WEAR OF POLYMERIC MATERIALS REINFORCED BY CARBON NANOTUBES [PDF]

open access: yesJournal of the Egyptian Society of Tribology, 2017
The present work studies friction coefficient and wear of polymeric materials such as high density polyethylene (HDPE), low density polyethylene (LDPE) and polystyrene (PS). The polymers are filled by carbon nanotubes (CNTs) in concentration up to 1.0 wt.

Optimization of ultrasonically welded High density polyethylene with Medium density polyethylene [PDF]

open access: yes, 2021
Abstract Ultrasonic welding is a mechanical system whereby high-recurrence ultrasonic acoustic vibrations are privately connected to workpieces being held together compelled to make a strong state weld. It is usually utilized for plastics, and particularly for joining disparate materials.

Cyclic Behavior of High Density Polyethylene (HDPE)

open access: yesAIP Conference Proceedings, 2010
This article presents the mechanical behavior of high density polyethylene (HDPE). Samples were prepared by extracting extruded HDPE pipe. Cyclic and strain rate jump behavior of HDPE were studied under uniaxial tensile loading conditions. The strain jump tests indicated that mechanical behavior of HDPE has deformation memory.

Experimental study of crack behavior in pressurized high-density polyethylene water pipes

open access: yesMethodsX, 2019
Leakage of High-Density Polyethylene pipes are more sensitive to pressure. Longitudinal slits are the most failure in High-Density Polyethylene pipes that occur in water distribution networks.

Microbial degradation of virgin polyethylene by bacteria isolated from a landfill site

open access: yesSN Applied Sciences, 2022
In this study we evaluate the extent of degradation of high-density polyethylene by bacterial isolates obtained from landfill. The microorganisms are isolated from plastic wastes deposited in the landfill for 2–3 years and 17 years.
