Designing efficient characterization technology of TGA and FTIR for compounding grade: Properties and design color selection

Abstract

The existing research looks into the physical properties of a blend of two-Lexan polycarbonates with differing properties (Melt Flow Index). Experiments were carried out in two steps, employing two diverse twin extruders: The (30/70%) of polycarbonate grade were melt-blended in the first phase utilizing (a Coperion rotating twin-screw extruder) named (SB). The grade was mixed in eleven steps in a twin-screw Thermo Haake Mini Lab II micro compounder in the second phase (ML). The phases (Wt.% PC1 and / Wt.% PC2) were (100 Wt.% / Wt.% 0%), (90 Wt.% /10 Wt.%), and (80 Wt.%, Wt.% 20%). (zero Wt.%. / one hundred Wt.%). Another experiment read out a material that was without pigment (WOP). To explore the characterization of polycarbonate compounding, a sample containing PC resin combined with colorant and additives (WP) was created. The rotational rheometer is used to rheologically define this grade at various temperatures in both stages. For the identical compositions, the research intends to identify a comparative characterisation study for viscosity using Thermogravimetric (TGA) and Fourier Transform Infrared (FTIR) Spectroscopy. TGA compounding samples were created with the effects of heating rate per second; glass transition temperatures (Tg) for PCs blends were measured and related to the effect of minute variation blends. When a sample absorbs infrared radiation, the FTIR technique allows for the identification and localization of compounds. The application was expanded to the polymer grade in order to extract the impact of the rheological characteristic, TGA, and FTIR to investigate their associations in the viscosity records and their impact results on properties and color matching design.
