HDPE monofilaments were obtained using different extruders and drawn by post-extruder equipments. After solidification, drawn and undrawn monofilaments (draw ratio 7:1) were irradiated with 10 MeV electron beams in air at room temperature at 25, 50, 75, 100 and 125 kGy dose ranges to induce a network structure. HDPE crosslinking was studied on the basis of gel content measurements. The fibers w...

The Hopkinson split pressure bar (HSPB) was used for the testing of three polymers at strain rates between 102 to 103 s-1. Higher were achieved using direct test. Experimental data evaluated in time as well frequency domain. A more detailed analysis domain showed that description tested can be described framework linear viscoelasticity. use test occurrence a permanent strain.

an essential characteristic for high performance inherently hydrophobic membranes such as microporous high density polyethylene (hdpe) membranes is to have a hydrophilic surface. in this project, wet chemical functionalization as a facile and effective method was developed to give a hydrophilic property to hdpe membranes using polar functional groups. kclo3, k2cr2o7 and kmno4 were selected as o...

The data set presented is related to the tensile behavior of cenosphere reinforced high density polyethylene syntactic foam composites "Processing of cenosphere/HDPE syntactic foams using an industrial scale polymer injection molding machine" (Bharath et al., 2016) [1]. The focus of the work is on determining the feasibility of using an industrial scale polymer injection molding (PIM) machine f...

Introduction. A new technique of implantation of high-density porous polyethylene nasal dorsal implants in Asians is described in this paper. Silicone sizers, which have smooth surfaces, were used to facilitate implantation of porous polyethylene implants in Asian patients. Materials and Methods. Twenty-three patients of Asian descent underwent dorsal augmentation rhinoplasty with open techniqu...

Hydrosilane-B(C6F5)3 adducts were found to activate zirconocene dihalides and generate ternary catalytic systems possessing moderate to high activity in ethylene polymerization to high density polyethylene (HDPE). The activation efficacy of the adducts increased with increasing hydride donor ability and decreased with steric crowding of the particular hydrosilane used. NMR investigation of the ...

The development of value-added products made from post-consumer plastic recyclates has become an important goal in the quest for a sustainable society. To attain such goal, tools with higher accuracy and wider scope are increasingly necessary. The present work describes the application of a Life Cycle Assessment (LCA)/Life Cycle Costing (LCC) integrated model, with inclusion of externalities (e...
