Material description
Polypropylene homopolymers are thermoplastic resins produced through the polymerization of propylene with Ziegler-Natta catalysts.
Ziegler-Natta catalyst, any of an important class of mixtures of chemical compounds remarkable for their ability to effect the polymerization of olefins (hydrocarbons containing a double carbon–carbon bond) to polymers of high molecular weights and highly ordered (stereoregular) structures
Propylene homopolymer has a high strength-to-weight ratio, and is stiffer and stronger than the copolymer. These properties combined with good chemical resistance and weldability make it a material of choice in many corrosion resistant structures

Copolymer Polypropylene
Copolymer polypropylene is a type of polymer compound that is a bit softer but has a comparatively better impact strength. Moreover, it is tougher and more durable than the homopolymer form of polypropylene. This polymer material tends to have better stress check resistance and low-temperature toughness compared to a homopolymer,
