Polypropylene (PP)
Polypropylene (PP) is a partially crystalline, very lightweight homopolymer thermoplastic (density 0.91 g/cm³) with excellent chemical and corrosion resistance. It withstands continuous service temperatures of up to 100 °C, with very low water absorption, good electrical insulation and excellent weldability. It is ideal for chemical engineering, tank construction, electroplating, ventilation equipment and laboratory technology.

Note: Homopolymer polypropylene, very lightweight and with high chemical and thermal resistance; available in several colors. Values are for reference and may vary by grade. In engineering plastics, composition is identified by the base polymer, the process and its modifications, not by chemical percentages as with steels. The information and values in this data sheet are provided for reference only and may vary depending on manufacturing and application conditions. They do not constitute guaranteed specifications, so use and interpretation of this data is the user's responsibility.
