Abstract
  In this research we provide a practical guide to achieve the successful extrusion of LDPE tapes commercially used in mesh fences, with controlled dimensions, good mechanical properties and weather resistance. Here we share: 1) The die design dimensions and its specialized slotted manufacture to get the ...  Read More

Characterization
LDPE and poly(1-butene) blends: Morphology, crystallinity and rheological properties

Reza Poorghasemi; Yousef Jahani

Volume 8, Issue 1 , January 2021, , Pages 21-30

https://doi.org/10.22063/poj.2020.2759.1164

Abstract
  In this work, the compatibility and crystallinity of low density polyethylene (LDPE) and polybutene-1 (PB-1) blends were studied. Various blends of LDPE/PB-1 containing 5, 10 and 20 wt.% PB-1 were prepared in a corotating twin-screw extruder and characterized by scanning electron microscopy (SEM), shear ...  Read More

Thermal-insulation performance of low density polyethylene (LDPE) foams: Comparison between two radiation thermal conductivity models

Rezgar Hasanzadeh; Taher Azdast; Ali Doniavi; Richard Eungkee Lee

Volume 6, Issue 1 , January 2019, , Pages 13-21

https://doi.org/10.22063/poj.2018.2185.1113

Abstract
  The loss of energy especially in industrial and residential buildings is one of the main reasons of increased energy consumption. Improving the thermal insulation properties of materials is a fundamental method for reducing the energy losses. Polymeric foams are introduced as materials with excellent ...  Read More

Volume 2, Issue 1 , January 2015, , Pages 39-47

https://doi.org/10.22063/poj.2015.1102

Abstract
  Pyrolysis of low density polyethylene (LDPE) by equilibrium fluid catalytic cracking (FCC) was studied in a stirred reactor under different process parameters. In this work, the effect of process parameters such as degradation temperature (420-510°C), catalyst/polymer ratio (0-60%), carrier gas type ...  Read More
