For a long time, the number of available bead foam variants limited to standard polymers which restricted their functionality mainly packaging, thermal insulation (e.g. in construction) and shock absorption transportation). In particular, such as expanded polystyrene, polyethylene polypropylene were used for components requiring good insulating properties high energy at low cost. Mainly since l...

Abstract Biodegradable PLA which is produced by polymerization of lactic acid derived from the starch plants a good candidate for replacing current petroleum-based polymers such as polystyrene (PS) or Polypropylene (PP) in food packaging application. These do contribute to large-scale environmental pollution it non-degradable polymer. Being classified Generally Recognized As Safe (GRAS) contact...

The objective of this study was to evaluate the influence different packaging on storage milk candy in tablets by means moisture, ash, lipid, protein, colour and texture profile analysis. were used: Expanded polystyrene wrapped with polyvinyl chloride film (PVC), polypropylene (PP) low-density polyethylene (PEBD) bags. experiment conducted a completely randomised design, evaluations carried out...

In this work, a study of the linear viscoelastic properties co-continuous polypropylene/polystyrene blends filled with multiwall carbon nanotubes (MWCNTs) is presented. The YZZ rheological model [W. Yu et al., Polymer 51, 2091–2098 (2010)] employed to correlate behavior their microstructure and electrical properties. A test design involving sequence small amplitude oscillatory shear time sweep ...

This study aims to develop a simulation-based research evaluate the influence of primary operational conditions on efficiency compression molding in processing thermoplastic parts mold design with no air venting. Moldflow Insight has been used simulate process assess quality range semi-crystalline and amorphous products, performance said mold. Simulation results were obtained by varying surface...

Microplastics (MPs) are present practically everywhere in the coastal ecosystems, including sediment of beaches and wetlands as well columns surface subsurface waters. Marine MPs most frequently found near shore zones. Due to their potential negative impact on ecosystem functions, have become a significant environmental problem worldwide. Contamination by microplastics has been well-documented ...

In this work, post-consumer polypropylene and wood flour from Pinus elliottii were used to produce wood plastic composites. The effect of polypropylene grafted with itaconic acid used as a coupling agent on mechanical properties, thermal stability and morphology of the composites was investigated and compared with the composite developed with polypropylene grafted with maleic anhydride, commonl...

We present an overview of the current literature and management techniques for vaginal extrusion or urinary tract erosion of graft materials used in pelvic floor reconstruction. A MEDLINE search was performed to identify literature pertaining to the incidence and management of vaginal or urinary tract exposure of graft materials commonly used in anti-incontinence and pelvic floor reconstructive...

A framework to self-consistently combine a classical equation of state (EoS) and molecular force field model polymers polymer mixtures is presented. The statistical associating fluid theory (SAFT- γ Mie) used correlate the thermophysical properties oligomers generate robust transferrable coarse-grained (CG) parameters which can be both in particle based simulations equations calculations. Examp...
