Statistical thermal stability of PVC
Experimental design was used to optimize the processing parameters for the decomposition of poly (vinyl chloride). Factorial design and face centered composite design (FCC) were applied to determine the optimum conditions. ...
A study of chemical and physical changes during biaxially oriented polypropylene film production
(Walter de Gruyter, 2003)
Polypropylene films obtained during the biaxial orientation process were characterized by energy dispersive X-ray analysis (EDX), scanning electron microscopy. X-ray diffraction, differential scanning calorimetry, infrared ...
The effect of zinc stearate on thermal degradation of paraffin wax
In this research, the effects of zinc stearate addition on paraffin wax degradation were investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG). The apparent activation energies of wax decomposition ...
Preparation and characterization of calcium stearate powders and films prepared by precipitation and Langmuir-Blodgett techniques
(American Chemical Society, 2010-02)
The preparation of calcium stearate (CaSt2) using precipitation and Langmuir-Blodgett techniques was investigated in this study. While sodium stearate and calcium chloride were used in the precipitation process, calcium ...
Preparation and characterization of magnesium stearate, cobalt stearate, and copper stearate and their effects on poly(vinyl chloride) dehydrochlorination
Preparation and characterization of pure metal soaps and investigation of their effects on poly(vinyl chloride) (PVC) dehydrochlorination were the objectives of the present study. Magnesium stearate (MgSt2), cobalt stearate ...
Dehydration, water vapor adsorption and desorption behavior of Zn[B3O3(OH)5] · H2O and Zn[B3O4(OH)3]
(Taylor & Francis, 2012-11)
The dehydration behaviors of two different hydrated zinc borate species, Zn[B3O3(OH)5] · H2O and Zn[B3O4(OH)3], which are industrially important flame retardants, were studied by thermal gravimetric(TG) analysis and in ...
