Relaxation Phenomena in Low-Density and High-Density Polyethylene. [PDF]
Polymers (Basel)A study was conducted on the internal friction spectra and temperature dependencies of the frequency of free damped oscillatory processes excited in the investigated samples of low-density polyethylene (LDPE) and high-density polyethylene (HDPE) over a temperature range from −150 °C to +150 °C.

NON-BIODEGRADATION OF POLYMERIZED POLYETHYLENE RADICALS AT SELECTED DUMPSITES IN KEFFI, NASARAWA STATE NIGERIA [PDF]
Journal CleanWAS, 2023 Polythene and plastic bags pollutes the soil because these are non-biodegradable, and so, they cannot be degraded by the action of the microbes. Therefore, they remain in the soil and will pollute the soil.

Mechanical properties of filled high density polyethylene
Journal of Saudi Chemical Society, 2015 Mechanical properties of (HDPE M624) with three filler (inorganic and organic) composites were assessed with respect to the effect of the filler content. The filler varied from (5% to 25%) by weight in the composite. Obvious improvement in the mechanical

ELECTROSTATIC CHARGE GENERATED FROM SLIDING OF HIGH DENSITY POLYETHYLENE AGAINST AIR BUBBLE SHEET OF LOW DENSITY POLYETHYLENE [PDF]
Journal of the Egyptian Society of Tribology, 2017 The present work investigates the electrostatic charge (ESC) generated from contact and separation as well as sliding of high density polyethylene (HDPE) on the air bubble sheets. They are made of low-density polyethylene (LDPE) of air-bubbles. They have

Epitaxial crystallization of linear low-density polyethylene on high-density polyethylene [PDF]
Journal of Materials Science, 1997 The oriented crystallization of linear low-density polyethylene (LLDPE) on high-density polyethylene (HDPE) has been investigated by transmission electron microscopy. From morphology and electron diffraction, it is confirmed that epitactic growth of LLDPE lamellae on the HDPE crystals takes place with an adoption of the HDPE crystal thickness at the ...

Fotodegradasi High Density Polyethylene Yang Mengandung Aditif Okso-Biodegradasi
Indonesian Journal of Chemical Research, 2017 High Density Polyethylene (HDPE) is a type of plastic that widely used for packaging because it has good mechanical properties. HDPE is naturally non-biodegradable, and the consequence it will increase plastic waste that will damage the environment.
