PP

Polypropylene is undoubtedly a remarkable material with a wide range of applications. As a semi-crystalline thermoplastic, it offers a unique combination of properties that make it very useful in various industries. Compared to polyethylene, polypropylene is known for its higher stiffness, hardness and strength, although these values are slightly lower compared to other plastics such as polyamide.

The material belongs to the polyolefin family, which means that it has similar chemical structures and properties to polyethylene. This relationship means that polypropylene is also used in many similar applications to polyethylene, particularly as an insulating material in cabling.

An outstanding property of polypropylene is its high inherent damping. This property allows the material to absorb and distribute mechanical energy, making it particularly suitable for applications where oscillations or vibrations need to be damped. For this reason, polypropylene is often used in power capacitors, where it helps to stabilise electrical signals and reduce noise.

Polypropylene is also used in the manufacture of membranes for loudspeakers. Due to its combination of strength, damping properties and light weight, polypropylene can produce high-quality speaker cones that enable precise and accurate sound reproduction.

Overall, polypropylene is an extremely versatile material that is used in various industries for a wide range of applications. Its unique properties make it an indispensable material in areas such as electrical engineering, the automotive industry, the packaging industry and many more.
