Polypropylene Block Copolymer (PP Block Copolymer) is a type of polypropylene created by incorporating long blocks of ethylene within the polypropylene molecular chain. This structure provides superior toughness and impact resistance compared to both homopolymer and random copolymer polypropylene. With a density of ~0.90–0.91 g/cm³ and a melting point of around 160°C, block copolymers exhibit high tensile strength and rigidity, making them ideal for heavy-duty applications. Unlike random copolymers, which are valued for their clarity, block copolymers are opaque but much stronger and more durable. They are widely used in automotive components, industrial crates, appliances, and outdoor applications where mechanical strength and resistance to cracking are critical. PP Block Copolymer resists moisture and chemical attack, maintaining stability under harsh conditions. It processes well in injection molding and extrusion, enabling the production of complex and strong parts. While non-biodegradable, it is recyclable under code #5, contributing to material sustainability in manufacturing. UV stabilizers are often required for outdoor applications due to its sensitivity to sunlight. Overall, PP Block Copolymer combines toughness, long lifespan, and lightweight properties, making it a go-to material for industries requiring durable and reliable plastics.
