Temporary skin fillers have been used for years for acne scar treatment, but a permanent dermal filler has since been approved for use by the FDA. Designed to remove moderate to severe acne scarring,Bellafillis made up of 80% collagen to replace lost volume and 20% polymethylmethacrylate, whi...
of the use of thermoplastic materials that are still in use today: polystyrene, PVC (polyvinyl chloride), polyolefins, and Perspex (polymethyl methacrylate).This laid the foundation of plastics use in manufacturing as we know it today. Soon, more items would be made of plastic than ever before...

PDMS, while being one of the most commonly used materials, is not the only polymer used for microfluidic applications. Polymethylmethacrylate (PMMA) and Polycarbonate (PC) are also good candidates and typically used with injection molding methods for chip fabrication, albeit these two materials are ...
New materials used quickly for example polystyrene and polymethylmethacrylate. (gas). All these plastic components become required and enormously popular during World War II as aspects of several military items for example radar units and airplane canopies. And here’s where plastic components and Cosm...
