Polypropylene (PP)

The workhorse thermoplastic of bottle caps and car parts, born from stereoregular catalysis.

Core Principles & Analysis

• Giulio Natta’s stereoregular polymerization of propylene in 1954 shared the 1963 Nobel Prize.
• Its isotactic chains pack into a crystalline, heat-tolerant plastic.
• The "living hinge" — a flexing strip that survives millions of cycles — is a polypropylene specialty.

Specifications & Metrics

• MONOMER: Propylene (C₃H₆)
