Composites based on recycled high density polyethylene (RHDPE) and natural fibers were made through melt blending and compression molding. The effects of the fibers (wood and bagasse) and coupling agent type/concentration on the composite properties were studied. The use of maleated polyethylene (MAPE), carboxylated polyethylene (CAPE), and titanium-derived mixture (TDM) improved the compatibil...

A melt flow indexer (MFI) was used to investigate high-temperature transitions in melts of high-density polyethylene (HDPE). The MFI data were obtained in the range 190–230°C. These transitions were found in the MFI at about 210 and 225°C and reproduced in a Haake melt blender. Polystyrene was used in the blender experiment to demonstrate typical amorphous behavior. For HDPE melts, the MFI–temp...

High-density polyethylene (HDPE) piping has been used in place of steel alloys in the petrochemical, power, and mining industries due to its exceptional resistance to corrosion and erosion. Recently, HDPE has also been used for nuclear safety-related cooling water applications. The application of nuclear quality assurance requirements creates reasonable assurance that the production fusion join...

The Balgrist hip socket, initially made entirely of HDPE (high molecular weight polyethylene), now made of outer titanium alloy shell that faces the bone of the acetabulum has been in clinical use for 10 years. The purpose of this presentation is to illustrate the biomechanical principles that have governed this unique design and to present the clinical results that we have obtained until the e...

Abstract A correlation effect between particle size of kaolin clay and injection moulding process parameters on impact strength, shrinkage warpage high-density polyethylene/kaolin (HDPE/KC) composites was carried out using analysis variance (ANOVA). Kaolin with sizes < 75, 75–106 106–150 μm used. The that were taken into consideration temperature, packing pressure time. In general, experimen...

This study seeks to evaluate the economic implication of a biogas digester built from composite material ascertain its cost effectiveness. The feasibility conducted indicates that brick made only fixed dome costs between USD 3193.99 and 4471.59. high is attributed construction material, thus prompting need use materials lower for affordability sustainability. Hence, under was comprising high-de...

The base polymer properties have been developed experimentally by adding small amounts of different fillers but they are expensive to the polymer material. Thus, it has been investigated that the incorporation of cost-less nanoparticles like clay and fumed silica nanoparticles into low density polyethylene LDPE and high density polyethylene HDPE which controlled the breakdown strength and volta...

Deep-water flexible composite pipes have been widely employed in the domain of deep-water oil and gas transportation, high-density polyethylene (HDPE) is used to seal inner sheath internal media containing H2S CH4, due its favorable barrier properties mechanical properties. The morphological evolution HDPE during extrusion process exerts a direct impact on material’s grand canonical Monte Carlo...

Microfibrillar composites (MFCs) from recycled high density polyethylene (R-HDPE)/recycled poly (ethylene terephthalate) (R-PET) (75/25 w/w) were made through reactive extrusion and post-extrusion strand stretching. The resultant MFCs could be processed at HDPE processing temperature. The compatibility between microfibers and R-HDPE matrix was improved through compatibilizers. Of the three comp...
