Polypropylene homopolymer (PP homo)
Description (definition)
Polypropylene homopolymer (PP homopolymer) is a pure form of polypropylene consisting exclusively of propylene monomers. It is characterized by high rigidity, temperature resistance and chemical resistance. PP homo is preferred in applications that require stability and durability, particularly in the automotive, packaging and household appliance industries.
Example
A typical example is the use of PP-Homo for the production of containers and buckets that have to withstand chemical cleaning agents. The high rigidity ensures dimensional stability, even under load.
What advantages does PP-Homo offer in technical applications?
PP-Homo offers excellent dimensional stability, rigidity and chemical resistance. This makes it suitable for demanding technical applications such as machine component housings or chemical-resistant pipes.
How does PP-Homo differ from polypropylene copolymer (PP-Copo)?
PP-Homo has a higher stiffness and temperature resistance than PP-Copo, but is less impact resistant. It is preferred in applications where mechanical strength is more important than flexibility.
Is PP-Homo environmentally friendly?
PP-Homo is fully recyclable and is often reused in closed recycling loops. The ability to use recycled material reduces waste and promotes sustainability.
