Valorization of silicone waste powder as industrial-waste-derived fillers in Bi2O3/EPDM nanocomposites for potential use in diagnostic X-ray protection

Thiwaporn Chumphon, Ariya Khamnuandet, Ekachai Wimolmala, Worawat Poltabtim et autres

This study valorized silicone waste powder (SWP) reclaimed from discarded silicone molds as a silica-rich secondary filler in ethylene–propylene–diene monomer (EPDM) composites containing nano-sized bismuth oxide (nano-Bi 2 O 3 ) for lead-free diagnostic X-ray shielding applications. To enhance filler–matrix compatibility, SWP …

Nano-BaSO4/waste PVC/natural rubber composites as lead-free and sustainable diagnostic X-ray shielding materials: Fabrication and performance evaluation

Jarosjan Veerathihiran, Ariya Khamnuandet, Prachnawadee Hongboon, Chalisa Moonlek et autres

Sustainable X-ray shielding composites based on natural rubber (NR), nano-barium sulfate (nano-BaSO 4 ), and waste poly(vinyl chloride) (w-PVC) were successfully developed for diagnostic X-ray protection applications. Prior to fabrication, the X-ray shielding properties of the composites were theoretically predicted using XCOM …
