Experimental investigation of adhesive meltblown web production using accessory air.
January 1, 2006... INTRODUCTION The melt-blowing technology is a one-step process for converting polymer into a microfiber structure web that dates back to the 1950s [1]. The meltblown products are suitable for medical materials, oil spill absorbents,...

Recycling of tire-curing bladder by ultrasonic devulcanization.
January 1, 2006... INTRODUCTION Rubbers do not decompose easily due to the presence of a 3D crosslinked structure, stabilizers, and other additives. However, after service, almost all the rubbers are discarded. Therefore, the disposal of waste rubbers is...

Production of electrically conductive networks in immiscible polymer blends by chaotic mixing.
January 1, 2006... INTRODUCTION Most polymers act as insulators due to low values of dielectric constants. Nevertheless, polymers are made conductive to derive many advantages over metals, e.g., desired electrostatic charge dissipation or electromagnetic...

Effect of the compatibility on toughness of injection-molded polypropylene blended with EPR and SEBS.
January 1, 2006... INTRODUCTION When a load applies to a specimen of a polymer with a notch, the local plastic deformation develops from the tip of the notch. If the stress at the tip of the notch is lower than the strength of fibrils in the craze,...

Crystallization characteristics of intercalated Poly(L-lactide)/organo-modified montmorillonite hybrids.
January 1, 2006... INTRODUCTION Polymer/clay hybrids have attracted much significant academic and industrial interest due to their remarkable enhancement in dimensional stability and gas barrier performance, in addition to mechanical properties as compared...

Gas-Assisted Injection Molding with fluids partially occupying straight or complex tubes.
January 1, 2006... INTRODUCTION Gas penetration in a tube, which is partially or completely occupied by a liquid, is a problem of fundamental and practical interest. A number of technologically important applications are known, such as the removal of oil...

Effect of the type of thermoplastic elastomer and solvent on the morphology and mechanical properties of polycarbonate blends.
January 1, 2006... INTRODUCTION Optoelectronic devices based on organic materials, such as the photoreceptor, are usually multilayer polymer composites, with each layer consisting of a functional small molecule dispersed in a polymer. For example, a typical...

Synergistic effect of compatibilizer in organo-modified layered silicate reinforced butadiene rubber nanocomposites.
January 1, 2006... INTRODUCTION Polymer nanocomposites based on the reinforcing of silicate layers derived from montmorillonite and thermoplastic or thermosetting polymers have been developed extensively over the past decade [1-5]. These materials have been...

Crystallization kinetics of poly(trimethylene terephthalate)/poly(ether imide) blends.
January 1, 2006... INTRODUCTION Crystallization kinetics in melt-miscible blends of crystalline and amorphous polymers has been extensively studied [1-15]. When crystallization occurs below the melting point of the crystalline component, the process involves...

Plasticization effects on bubble growth during polymer foaming.
January 1, 2006... INTRODUCTION The foaming of polymer melts has been studied by many authors, both theoretically [e.g., 1-8] and experimentally [e.g., 9-12]. Extensive reviews and references can be found in a handbook edited by Klempner and Frisch [13] and...

Terminally functionalized polyethylenes as compatibilizers for wood-polyethylene composites.
January 1, 2006... INTRODUCTION Wood-plastic composites (WPCs) have experienced rapid growth because of various advantages of wood, such as low cost, low specific gravity, renewability, and reduced wear on processing equipment. However, poor compatibility...

Rheology of wood plastics melt, Part 3: nonlinear nature of the flow.
January 1, 2006... INTRODUCTION The past decade has seen a rapid expansion of the wood plastics industry [1-3]. Among the many factors for this rapid development, the economic competitiveness associated with high filler contents is in no doubt an important...
