High‐density polyethylene reinforced with submicron titania particles [PDF]
Polymer Engineering & Science, 2008 AbstractSubmicron titania particles were prepared by means of two different synthetic procedures in order to obtain different particle size (diameter ranging from 20 to 350 nm), shapes, and morphologies (amorphous or crystalline). Titania particles were surface modified with octadecylsilane in order to improve their compatibility with respect to ...

Attrition of high-density polyethylenes
Powder Technology, 1987Abstract An annular shear cell has been deployed to explore the influence of polymer structure on bulk attrition for various grades of high-density polyethylene, these grades differing in molecular weight and degree of chain branching. Decreased bulk attrition of coarse material was found, provided that the molecular weight was high.

Bone growth into porous high‐density polyethylene
Journal of Biomedical Materials Research, 1976AbstractThe purpose of this study was to delineate the process by which bone comes to fill the pores of porous high‐density polyethylene (PHDPE) implants. PHDPE (450μ pore size) pellets 4 mm in diameter and 1 cm long were implanted into the femurs of dogs.

Stabilization of high‐density polyethylene
Journal of Applied Polymer Science, 1968AbstractSeveral types of antioxidants are evaluated in high‐density polyethylene for color and physical property stabilization during processing and thermal aging. A wide variety of evaluation tests are used and discussed. Heat‐ and light‐induced oxidation mechanisms are reviewed.

Weathering of High-Density Polyethylene-Wood Plastic Composites
Journal of Wood Chemistry and Technology, 2013Due to widespread use of wood-plastic composites, high density polyethylene-wood flour composites (HDPE/WF) were studied in order to determine their stability in different application conditions. UV degradation and periodic absorption/desorption of moisture cause damaging changes to material during WPCs exterior application so it is needed to ensure ...

AbstractThe effect of high‐density polyethylene (HDPE)/polypropylene (PP) blending on the crystallinity as a function of the HDPE melt index was studied. The melting temperature and total amount of crystallinity in the HDPE/PP blends were lower than those of the pure polymers, regardless of the blend composition and melt index.

High‐density polyethylene (HDPE) and maleic anhydride grafted HDPE (HDPE‐g‐MA) were selected as lubricant and compatibilizer, respectively, for improving the tribological and mechanical properties of polycarbonate (PC). The morphology of worn surfaces and debris was observed by means of scanning electron microscopy (SEM).

Wear of high-density polyethylene on bone and cartilage
The Journal of Bone and Joint Surgery. British volume, 1979Wear of high-density polyethylene on bone and cartilage has resulted in a large volume of plastic particles being shed into the two knees and two hips studied. The giant-cell foreign-body reaction of the synovium may not be sufficient to cope with the amount of debris presented and the destruction of the endosteal bone in one hip, caused by the wear ...

Nucleation of Iow density polyethylene by high density polyethylene
Journal of Materials Science Letters, 1988The spherulitic morphology of semicrystalline polymers can be influenced by nucleating agents. With high concentrations of such agents a morphology results which consists of small spherulites. This effect is used, for example, to increase the optical transparency of films or to increase the toughness [1].
