Proteus™ Homopolymer PP White shapes are characterized by their high strength-to-weight ratio, excellent chemical and corrosion resistance capabilities, thermoforming performance and zero moisture absorption. In addition to these key properties, this grade also displays a minimal centerline porosity composition and is FDA and NSF compliant. As a result, Proteus™ Homopolymer PP White components are ideal for chemical and food processing and storage and medical applications, such as orthotic and prosthetic devices, pump components, storage tanks and valve bodies.
