Controle de qualidade na indústria de polímeros

Abstract

Since their discovery, polymers have become a target for humanity's potential applications. With the goal of large-scale production, synthetic polymers began to be developed. These polymers, whether conventional, biodegradable, or based on renewable resources, must undergo rigorous laboratory quality control processes to generate lower costs and achieve high profitability. Based on this principle, this paper aims to explain methodological processes applied in a high-end polymer industry, describing the results obtained and the expected standard parameters to better elucidate quality control. Specifically, the following are cited: quantitative analyses of load, flowability, and moisture control, and qualitative analyses of color, odor, and pellets of the polymeric materials manufactured in an extruder: PPTD20HF, PPTD20Alternative, Black Compound SX Plus, New White Compound, and PPC4760R; In addition to reporting on the preventive and corrective inspection of the machinery, the process flowchart was prepared. The analysis results revealed non-compliance in the moisture content of bags 3 and 4 of the PPTD20HF. However, the implemented action plan allowed the bags to be released for shipment the following week. These methodological processes have important implications for application in industries across the market, optimizing material performance and efficiency.
