As a result of the Titans of Greek mythology. Titanium was named after Heinrich Klaproth. a German chemist. who discovered and named it in rutile in 1795. Because of the metal's high strength-to-weight ratio. he named it after the Titans for its strength and intensity.

The calorific value of a material is a measure of the energy released during its combustion. Polypropylene, a commonly used plastic in various industries due to its properties, has a significant calorific value. Specifically, the calorific value of polypropylene is approximately 19,900 to 20,000 BTU/lb (British Thermal Units per pound). This high calorific value indicates that polypropylene can release a substantial amount of energy when burned, which is why it finds utility in waste-to-energy plants as a potential fuel source. However, it's important to consider the environmental impact of burning plastics such as polypropylene, as it can lead to the release of harmful pollutants. Alternative disposal methods and recycling are recommended to minimize this impact.

Young's modulus, often referred to as the elastic modulus, is a measure of the stiffness of a material. For polypropylene, a common thermoplastic polymer, Young's modulus typically ranges from 1300 to 1800 MPa, demonstrating its relatively flexible nature compared to more rigid plastics or metals. This variability can depend on the molecular orientation and processing method of the polypropylene. Understanding the Young's modulus is crucial for engineers and designers who utilize polypropylene in applications where flexibility and strength are key concerns, such as in automotive parts, containers, and packaging. Adjustments in the polymer processing can alter its mechanical properties, including Young's modulus, to suit specific application requirements.
