How is a polymer broken down
WebLayer to layer fusion with heat is one of the main principles that many 3D printers rely on. The extrusion temperature for the polymer is also the welding/fusion temperature. Parts … WebSteam cracking is a petrochemical process in which saturated hydrocarbons are broken down into smaller, often unsaturated, hydrocarbons. It is the principal industrial method for producing the lighter alkenes (or commonly olefins), including ethene (or ethylene) and propene (or propylene).
