PP
Polypropylene
PP is a versatile, semi-crystalline thermoplastic with an excellent balance of properties. It is lightweight (density 0.905 g/cm³), chemical resistant, and has outstanding fatigue resistance. Its hinge-like flexural properties make it ideal for living hinge applications. PP is widely used in packaging, automotive, medical, and consumer goods.
