Effect of additives on flexible PVC foam formation
(Elsevier, 2008-01)
In this study, effects of Ca/Zn stearate and organotin heat stabilizers and zeolite, CaCO3, cellulose and luffa flours fillers, and their concentrations (2.5, 5, 10 and 20% by weight) on production of flexible PVC foams ...
Synergistic effect of natural zeolites on flame retardant additives
(Elsevier, 2005-09)
The thermal degradation and flammability of intumescent fire-retardant polypropylene matrix composites consisting of ammonium polyphosphate (APP) as an acid source and blowing agent, pentaerythritol (PER) as a carbonisation ...
Dye adsorption behavior of Luffa cylindrica fibers
(Elsevier, 2008-05)
Using natural Luffa cylindrica fibers as adsorbent removal of methylene blue dye from aqueous solutions at different temperatures and dye concentrations was investigated in this study. Thermodynamics and kinetics of ...
Optimisation of the effect of colemanite as a new synergistic agent in an intumescent system
(Elsevier, 2006-07)
An intumescent system including ammonium polyphosphate (APP) as an acid source and blowing agent, pentaerythritol (PER) as a carbonific agent and colemanite as a synergistic agent is used to enhance flame retardancy of ...
Influence of surface modification of fillers and polymer on flammability and tensile behaviour of polypropylene-composites
(Elsevier, 2006-05)
An intumescent system consisting of ammonium polyphosphate (APP) as an acid source and blowing agent, pentaerythritol (PER) as a carbonific agent and natural zeolite (clinoptilolite, Gördes II) as a synergistic agent was ...
