    PP: Polypropylene is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties,
    resistance to various organic solvents and acid-base corrosion. It has a wide range of applications in the industry
    and is one of the most commonly seen polymer materials.

    PS: Polystyrene, which has very good geometric stability, thermal stability, optical transmission characteristics,
    electrical insulation properties, and a very small tendency to absorb moisture. It is resistant to water, diluted
    inorganic acids, but can be corroded by strong oxidizing acids such as concentrated sulfuric acid and can swell
    and deform in some organic solvents.
