Compatibility of HDPE/postconsumer HDPE blends using compatibilizing agents
Journal of Applied Polymer Science, 2006AbstractMechanical properties, molecular weight, X‐ray diffraction, and differential scanning calorimetry (DSC) characterization of blends of virgin high‐density polyethylene (HDPE) with two types of recycled material were investigated. The recycled came from urban plastic waste; one kind was only washed and grounded and the other was extruded and ...

AbstractAsh‐based polymer composites are assuming increasing importance because of the pollutant potential, fine particle size, and low price of ash. Fly ash and rice husk ash are two prominent ash materials on which some investigations have already been done for potential use in polymer composites. This article highlights the results of a study on the

Primary polymer recycling involves the reprocessing of defective parts and scraps in a processing line. The critical limitation for excessive use of primary recycling consists of the need to maintain the properties of the polymer above the required minimum level.

Compatibilization of irradiated HDPE
Journal of Thermoplastic Composite Materials, 2014The C–O, C=O, and C(=O)O groups were introduced onto high-density polyethylene (HDPE) chains by ultraviolet irradiation in air and the groups’ content increased with increase in the irradiation time. When they irradiated for 16 h, gels were formed in the irradiated HDPE, and the content of the gels increased with increase in the ...

Effect of Ultraviolet Irradiation on Structure and Properties of HDPE and HDPE/STC Blends
Journal of Macromolecular Science, Part A, 2004Abstract Some oxygen‐containing groups such as C˭O and C–O were introduced onto high‐density polyethylene (HDPE) chains by an ultraviolet irradiation technique without the addition of any additives, and this method causes no chemical pollution to the environment. This groups content increases with irradiation time.

Compatibilization of ABS/HDPE by maleic anhydride grafted HDPE
This research investigated the compatibility of acrylonitrile butadiene styrene (ABS) – high-density polyethylene (HDPE) blends by maleic anhydride grafied polyethylene compatibilizer (HDPE-g-MAH). The compatibilizer was prepared by a reactive melt grafting of MAH loadings of 1, 2 to 5 phr on HDPE backbone with 0.5 phr dicumyl hydroperoxide initiator ...openaire +1 more source
Rotational molding of recycled HDPE
2001A significant fraction of the polymeric wastes consists of high density polyethylene for blow molding typically recycled in injection molding and extrusion processes but very often wasted. On the other hand, the polyethylene grades used in Rotational Molding technique are much less available as recycled polymers.
