Proteus™ Homopolymer PP Natural 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 is also FDA and NSF compliant making it ideal for chemical processing, food processing, storage and medical applications. For their performance and compliance, Proteus™ Homopolymer PP Natural components are often favored in orthotic and prosthetic devices, pump components, storage tanks and valve bodies.
