Low density polyethylene–chitosan composites: A study based on biodegradation

Biodegradation of high density polyethylene using Streptomyces species

“…Maximum biodegradation percentage was obtained for the sample with particle size of 212 microns which was about 18.2%. The results of experiments were reasonable compared to the literature [1,10,18] which proves high performance of Streptomyces species compared to the other microorganisms.…”

The performance of mengkuang leaf fiber reinforced low density polyethylene composites

“…For the extrusion process involving the polyethylene, most commonly used screw speeds are 60 rpm [22,23]. In twin screw extruder machine, there are temperature of zone 2, zone 3, zone 4, zone 5, zone 6, and die, need to be set up to enable the extrusion process.…”

Oxygen Permeability Coefficient of High Density Polyethylene/Cu Nanofibers Nanocomposites below Percolation

“…or inorganic fibers made from materials such as clay, alumina, glass, boron, silicon carbide, carbon etc. It was found that mechanical properties of polymer composites can be enhanced with increasing nanofiller content-as documented in literature [5][6][7][8][9][10][11][12][13][14][15][16] . It was also found that barrier to gas properties of the polymer composites can be enhanced (i.e.…”

“…However, the relationship in Figure 4 does not pass through the origin and as seen in Figure 4 at E c /E m =1.09 the value of P m /P c =1, which means that at small contents of Cunanofiber the value of P c is close to the permeability to oxygen coefficient for HDPE matrix. (9) In addition to that, the experimental Oxygen Transmission Rate (OTR) from Bikiaris & Triantafyllidis 31 study through each film was converted to permeability coefficient using the following equation…”
