The primary distinction between PPSU and PP is that PPSU is a medical-grade plastic with a natural honey tone and is highly durable, whereas PPSU is polypropylene, which is lightweight, slightly opaque, and suited for everyday usage.

This material is moldable and frequently used in quick prototyping and manufacturing processes. Heat and chemicals do not affect PPSU. As a result, it can be employed in plumbing, aeronautical, and automotive applications. It also doesn’t have a melting point because of its amorphous nature. Additionally, it provides tensile strength up to 55 MPa. Radel is the brand name for this substance. Additionally, PPSU fittings in plumbing applications might develop cracks or break due to faulty installations that use non-manufacturer-approved installations.

The letters PP and PPSU stand for polypropylene and polyphenylsulfone, respectively. The main distinction between PP and PPSU is that the former is a regular-use plastic with a light, slightly opaque tint while the latter is a medical-grade plastic with a natural honey tone that is highly durable.
