Due to recent developments in composite formulations and coating technology, polyvinyl chloride (PVC)-coated textiles are becoming increasingly popular in the textile industry. The most critical properties of PVC-coated textiles are their mechanical characteristics and morphological properties because they control their cost well. This study focuses on the impact of filler diameter and content on the mechanical properties of the PVC foam layer used for coated textiles stuffed with Vietnam calcium carbonate (CaCO3). The mechanical properties of the PVC foamed layer (breaking load, tearing strength and elongation at break) were studied. The applied contents were found to significantly influence the mechanical properties of the PVC foamed layer. The addition of CaCO3 fillers improved their mechanical properties. The results also showed that mechanical properties were enhanced using calcium carbonate with different particle sizes; the smallest particle size gave the highest mechanical resistance. The morphology of the different samples showed that the employment of calcium carbonate increases foam formation. A higher CaCO3 content can deteriorate the PVC foam layer structure. Using a small filler particle diameter decreased pore sizes and ameliorated the regularity in pore size distribution.
It is important to know that calcium carbonate is the cheapest chemical among all the others used in the production of the polymeric layers used for PVC coated textiles. Through various analyses, we found that both the content and particle size of calcium carbonate have strong effects on mechanical and morphological properties. In particular, the most significant effect was detected when using fine calcium carbonate particles for the production of the PVC internal layer. The low filler concentration of calcium carbonate resulted in positive changes in mechanical and structural characteristics. However, the structure of the PVC layers becomes mechanically poor at higher filler rates. These outcomes have been confirmed by many studies that have investigated the effect of the content and particle size of calcium carbonate on the final properties of PVC materials. The effects of calcium carbonate content and particle size on the behaviour of PVC in fires; thus, the effect of CaCO3 content and particle size on the thermal characteristics of PVC-coated textiles will be evaluated in subsequent work.
We offers a wide range of Vietnam Calcium Carbonate of different particle size assuring that our different clients will receive suitable quality material with cost-efficiency. We have the purest and brightest source of calcium carbonate and exploit the high standard of sustainability with uncoated and coated Calcium Carbonate (Stearic acid coating Calcite Powder). Raw materials are chosen carefully and the production process is conducted in ISO standard factories to ensure the most consistent quality for end-users.
Uncoated calcium carbonate is natural calcium carbonate obtained from high purity Vietnam lime stone. It is used in many industries as filler to reduce production cost. We can provide a wide range of particle size from 5 to 450 microns.
Coated calcium carbonate is made from uncoated calcium carbonate with 1% stearic acid. It is used for replacing some expensive polymers and additives to reduce production cost with particle size ranging from 5 to 45 microns.
We offers a wide range of calcium carbonate of various particle size, Uncoated and Coated Calcium Carbonate (Stearic acid coating Calcite Powder).
