Effect of calcium carbonate particle size and content on the thermal properties of PVC foamed layer used for coated textiles

Abstract

The goal of this research is to see how the amount and particle size of calcium carbonate (CaCO 3 ) used in the foamed layer in use for PVC-coated textiles affects the thermal properties of the material. Two different particle sizes were used at various concentrations. The impact of different CaCO 3 loadings and particle sizes on the PVC foamed layer’s thermal properties were examined. Thermogravimetry (TGA and DTG) and differential scanning calorimetry (DSC) measurements were utilized to investigate the thermal properties of the PVC foamed layer and the samples have been also characterized by FTIR spectroscopy. According to the findings, the thermal stability of the foamed layer was improved with the addition of calcium carbonate. Through the higher surface area between the filler and the PVC matrix, smaller particle sizes have produced the best results. The PVC foamed layer shows also changes in FTIR spectra after adding CaCO 3 , and the intensity of peaks increases with decreasing CaCO 3 particle size.

Exploring the synergistic effect of inorganic and organic particulates in polyvinyl chloride composites through comparative analysis and accelerated weathering

“…5 Many researchers in their recent work have demonstrated the use of calcium carbonate in PVC composites. [6][7][8] In a research work the impact and tensile strengths of calcium carbonate filled PVC composite increased with decreasing calcium carbonate particle size. 9 In another work upon the addition of up to nanocalcium carbonate in the PVC, researchers reported an increase in the impact and flexural strength but a decline in the tensile properties of the composite.…”

Recycled PVC content and particle size distribution effects on morphological and mechanical properties of expanded PVC layer for floorcoverings

“…Coated textiles emerge through the application of a polymer coating onto a textile substrate, resulting in a symbiotic fusion of materials.The different structural profile [4][5][6][7][8]. The harmonious integration of these constituents culminates in the creation of a plastisol, achieved through meticulous blending.…”

“…The different layers of a PVC-coated textile work together to provide the material with its desired properties [4][5][6][7][8][9][10]. This makes PVC-coated textiles a versatile material that can be used in a variety of applications, such as footwear, automobiles, floorcovering and wall coverings, upholstery, clothing, and many more.…”

“…Other studies [3][4][5]38,39] have explored filler (calcium carbonate CaCO 3 ) diameter and content impact on the mechanical properties of PVC foam layers in coated textiles. Stambouli et al [5] observed negative structural impacts with excessive CaCO 3 content (100 parts filler to 100 parts pure PVC resin) but noted that smaller filler particle diameters improve mechanical properties.…”
