The effects of blend ratio, compatibilization and dynamic vulcanization on permeation of gases through HDPE/EVA blends

Effect of PE-g-MA compatibilizer on the structure and performance of HDPE/EVA blend membranes fabricated via TIPS method

“…Due to the low cost, availability of PE and EVA polymers and good proccessability, PE/EVA blends are fabricated to be used in many applications (Faker et al, 2008). Blends of HDPE and EVA are a new class of thermoplastic elastomers, which couple the superior properties of HDPE and EVA and open up new avenues for the commercial use of these blends (John et al, 2011). The mechanical, rheological and thermal properties of PE and EVA blend polymers have been well studied (Ray and Khastgir, 1993;Poen et al, 2003;Khonakdar et al, 2004;John et al, 2010).…”

“…Although the advantage of the use of polymer blend in the TIPS process is that pore size can be controlled by the addition of second polymer due to changes in thermodynamics and kinetic properties (Fu et al, 2006), however, there are very few reports regarding the application of PE/EVA blend polymers in fabrication of membrane. Reported results are mainly discussed regarding the gas separation properties of PE/EVA blends; however, due to the low compatibility between PE and EVA, the reported results were a bit out of the Robson's tradeoff curves (Majid et al, 2010;Mousavi et al, 2010;John et al, 2011).…”

Mechanical and Oxygen Barrier Properties of LDPE/MMT/MAPE and LDPE/MMT/EVA Nanocomposite Films: A Comparison Study

“…14 Also EVA is more permeable than LDPE and this increase in permeability may be because of higher content of high permeable material. 35 Dadfar et al have also reported the increase in oxygen permeability with increasing EVA concentration in HDPE/EVA/MMT system. 36 …”

Influence of crosslinking on crystallization, rheological, and mechanical behaviors of high density polyethylene/ethylene‐vinyl acetate copolymer blends

“…Although PE and EVA are not immiscible , the vinyl consequence in EVA results in the same crystal structure with PE and partial miscibility at the interface of PE/EVA blends . Blending EVA of a proper vinyl acetate (VA) content with high density polyethylene (HDPE) allows producing a class of thermoplastic elastomers (TPEs) coupling the superior properties of both components . For example, addition of EVA could improve transparency, environmental stress cracking resistance, capacity of filler carrying, and impact properties of HDPE , which, however, usually leads to a great reduction in tensile strength ( σ b ) .…”
