A Study on the Dewaxing Behavior of Carbon-Black-Modified LDPE–Paraffin Wax Composites for Investment Casting Applications

Process Parameter Optimization for 3D Printed Investment Casting Wax Pattern and Its Post-Processing Technique

“…found in the works of Gill et al [21] and Glenda Webber [20]. For example, Glenda Webbe performed DSC analyses on several commercial HDPE waxes and found melting temper ature ranges that are very close to what was found in the current research.…”

“…A non-apparent two-stage degradation pattern is observed, and the degradation start of low molecular weight components can be identified during the first step of degradation. From the analysis results, the wax filament may be polyethylene-based synthetic composite wax due to similarities found in the works of Gill et al [21] and Glenda Webber [20]. For example, Glenda Webber performed DSC analyses on several commercial HDPE waxes and found melting temperature ranges that are very close to what was found in the current research.…”

Stabilization of an Aqueous Bio-Based Wax Nano-Emulsion through Encapsulation

“…Although the degradation temperatures for carnauba wax and the pure SMI nanoparticles became close to each other, the broader degradation interval for the carnauba wax was expected, depending on its more complex composition, with species of different molecular weight. In literature, the binary mixtures of a carnauba wax with polymers resulted in a two-step degradation pattern with weight losses corresponding to the carnauba wax concentrations, and the highest degradation temperature at 400 to 420 °C corresponding to the virgin carnauba wax degradation [ 60 ]. However, the same quantitative analysis could not be successfully made for the present carnauba wax nanoparticles, as more chemical interactions between the carnauba wax and imidized organic phase were demonstrated in the analysis presented earlier.…”

Review of hospital plastic waste management strategies for Pakistan

“…For example, intravenous (IV) bottles of glass, tubing made of rubber, and surgical instruments of metals were used widely until the 1930s when IV bags of polyvinyl chloride (PVC), tubing of PVC, and catheters made out of silicone were introduced (Modjarrad and Ebnesajjad 2003 ). Nowadays, polymers, rubbers, and polymer composite–based materials have occupied the market in the field of food packaging, medical instruments, furniture, automotive, health care instruments, and various other applications (Abid et al 2012 ; Adeosun et al 2013 ; Gill et al 2018 , b , c ; Salernitano and Migliaresi 2020 ; Zagho et al 2021a ; Zeng et al 2021 ). The utilization of plastics in medical devices includes simple tools such as spatulas, syringes, and dressings along with complex instruments, i.e., MRI, X-ray machine, surgical devices, etc.…”

“…Besides the disposal of hospital plastic waste, another feasible option for its treatment is recycling. Upgradation of the properties of recycled plastics is another way for the utilization of plastic waste as a base polymeric material for the fabrication of polymer-based nanocomposites in the field of non-medical applications (Gill et al 2012 , b , c ; Mamoor et al 2014 ; Vogt and Nunes 2014 ) Nevertheless, they can be recycled into non-food and non-medical graded items such as coat hanger (Vogt and Nunes 2020 ). Similarly, IV bags (PVC) which can be 10% of the total plastic waste are 90% non-infected and can be recycled (Lee et al 2021a ).…”
