In the evolving world of waterproof flooring, the wear layer serves as the frontline defense against daily wear. Among emerging technologies, polypropylene (PP)-based wear layers are revolutionizing WPC (Wood Plastic Composite) and SPC (Stone Plastic Composite) flooring with their unique blend of durability and flexibility.
Why Polypropylene Stands Out
Semi-crystalline polymer structure balances rigidity and impact resistance
Lower density than PVC (0.89-0.91 g/cm³) reduces overall flooring weight
Hydrophobic nature enhances moisture resistance

Key Technological Innovations
Cross-linked PP: Through electron beam processing, wear layer durability increases by 40% (AC4 rating achievable)
Nanocomposite Additives: Titanium dioxide nanoparticles provide self-cleaning properties
Recyclability: 100% PP composition supports cradle-to-cradle recycling
