LDPE/EPDM Multilayer Films Containing Recycled LDPE for Greenhouse Applications

Journal of Polymers and the Environment, 2001
In this paper the reuse of recycled LDPE in combination with the incorporation of EPDM modifier in the production of greenhouse films has been investigated. A three-layer film (60-100-40 micron thickness) containing recycled LDPE in the middle layer and a high UV-stabilized 40-micron outer layer was developed and proven to be commercially successful ...

LDPE–wood composites utilizing degraded LDPE as compatibilizer

Composites Part A: Applied Science and Manufacturing, 2013
Abstract The effect of degraded low-density polyethylene (dLDPE) as compatibilizer on the morphology and properties of low-density polyethylene (LDPE)/wood flour (WF) composites was investigated. The formation of functional groups on the degraded polyethylene chains enables the dLDPE to be used as a compatibilizer. The SEM images show smooth surfaces

Space charge behavior near LDPE/LDPE interface

2000 Annual Report Conference on Electrical Insulation and Dielectric Phenomena (Cat. No.00CH37132), 2005
We investigated the space charge behavior near the interface between different low-density polyethylene (LDPE). Charge carriers were mainly injected from the semiconductive electrode in a specimen of Al/LDPE/LDPE/semiconductive layer and they moved through the interface to the counter Al electrode.

Melt Rheology of LDPE and Glass Bead Filled LDPE Composite

Journal of Reinforced Plastics and Composites, 1999
The effects of shear rates and temperatures on the melt shear viscosity (17w) and the relationship between the first normal stress difference (NI) and the wall shear stress (Tr,,) of low density polyethylene (LDPE) and glass bead filled LDPE composite, over a temperature range from 130 to 1 70'C and shear rates varied from 100 to I 10 S-l, have been ...

Blends of LDPE/chitosan using epoxy‐functionalized LDPE as compatibilizer

Journal of Applied Polymer Science, 2011
AbstractLDPE and chitosan blends were prepared using an epoxy‐functionalized polyethylene as compatibilizing agent for improving interfacial adhesion. Compatibilization improved both tensile and flexural properties (with values approaching close to that of neat LDPE) when compared with that of uncompatibilized blends.

Effects of LDPE/nanofilled LDPE interface on space charge formation

2013 IEEE International Conference on Solid Dielectrics (ICSD), 2013
Space charge characteristics of double-layer dielectric, which consists of low density polyethylene (LDPE) and nano-titania filled LDPE (named TiO2-LDPE), have been tested by pulsed electro acoustic (PEA) method under different high voltage direct current (HVDC) electric fields.

Dielectric properties of POSS/LDPE and MgO/LDPE nanocomposites compounded by different techniques

2017 IEEE Conference on Electrical Insulation and Dielectric Phenomenon (CEIDP), 2017
Metallic oxide reinforced thermoplastics are good candidates as insulating material for HVDC cables because of their ability to limit or suppress space charges injection and accumulation. Furthermore, materials for applications for electrical engineering must also be able to evacuate heat.

Improving the properties of LDPE/glass fiber composites with silanized‐LDPE

Polymer Composites, 2008
AbstractLow density polyethylene (LDPE) is a widely used thermoplastic. The dispersion of inorganic fillers in thermoplastic matrices such as polyethylene has been largely employed to improve some of its properties. However, interaction between both components is a major issue so the presence of a coupling agent is usually necessary to increase the ...

Structure–property–processing relationships in chemically modified LDPE and LDPE/LLDPE blend

Journal of Applied Polymer Science, 1998
The properties of low-density polyethylene (LDPE) and its blend with linear low-density polyethylene LDPE : LLDPE (75 : 25) modified with varying concentrations of dicumyl peroxide (DCP) were compared. Chemical modification was carried out in a Brabender plasticorder under set conditions of temperature, rotor speed, and time.

Characteristics of LDPE pyrolysis

Korean Journal of Chemical Engineering, 2002
Pyrolysis of low-density polyethylene (LDPE) was studied in order to relieve environmental pollution and recover the monomer or fuel. LDPE was thermally decomposed with and without catalyst. First, efficiency of oil production was analyzed according to the variation of reaction conditions such as reaction temperature, types of additives and catalyst ...
