Thermal stabilization of polyvinyl chloride by calcium and zinc carboxylates derived from byproduct of palm oil refining

Preparing epoxidized vegetable oil from waste generated by the kapok fiber industry and assessing its thermal stabilization effect as a co-stabilizer for polyvinyl chloride

“…The thermal stability of PVC was tested both statically and dynamically, using a dehydrochlorination apparatus and a two-roll mill, respectively. These methods were previously described [ 25 ]. The dehydrochlorination apparatus consisted of an oil batch provided with a heating tape, a temperature controller, and a 7 mm ID, 1 mm thick glass test tube.…”

“…To prevent thermal degradation due to instability at processing temperatures, a thermal stabilizer is necessary when working with PVC resin [ [21] , [22] , [23] , [24] ]. Ca/Zn-based thermal stabilizers are commonly utilized in the industry due to their cost-effectiveness and environmental friendliness, as opposed to conventional lead-based thermal stabilizers which are being phased out in many regions [ [25] , [26] , [27] ]. Ca/Zn-based thermal stabilizers are typically prepared from fatty materials, such as stearic acid.…”

Influence of Nitrogen-Modified Atmosphere Storage on Lipid Oxidation of Peanuts: From a Lipidomic Perspective

“…The acid value (AV) of oil was determined according to the literature [18]. Moreover, 0.5 g oil sample was dissolved in 50 mL ethanol, and the solution was shaken well.…”
