Polypropylene carbonate (PPC) is a versatile polymer that finds applications in various industries due to its unique properties and characteristics. From biodegradable plastics to pharmaceuticals, PPC offers a range of benefits that make it suitable for diverse uses.
Calcium peroxide is a solid chemical used as a source of oxygen or hydrogen peroxide. When placed in water, calcium peroxide begins to decompose and release oxygen. When treated or dissolved in acids, calcium peroxide forms hydrogen peroxide. Calcium peroxide is a pale yellow, granular or powdered solid oxidizer.
Before we explore how hydrogen peroxide is made, let’s look at what it is. Hydrogen peroxide (chemical symbol H2O2 – it’s basically water with an extra oxygen atom!) is a weakly acidic, colourless liquid which can easily be mixed with water.
Hydrogen peroxide (H₂O₂) is a simple compound consisting of two hydrogen atoms and two oxygen atoms. It is available in various concentrations, typically ranging from 3% for household use to higher concentrations for industrial applications.
