High-Density Anti-Slip Shock Absorption MPP Foam for Battery Separator Flame Retardant Lightweight With High Strength

Product Introduction

MPP Microporous Foaming Material, also known as Microporous Foamed Polypropylene, is a new type of material that forms tiny internal bubbles through a special process. Its unique microporous structure (cell diameter: 0.1~50 microns, cell density: 10⁷~10⁹ per cm³) endows it with excellent comprehensive performance. Compared with unfoamed materials, its overall density can be reduced by 5%-95%, while maintaining high impact strength, good toughness and specific strength. The preparation process is green, environmentally friendly and odorless, with no chemical residues, complying with international environmental requirements. It is widely used in fields requiring lightweight design, such as new energy, electronics, automotive and packaging.

Core Features

  • High Flame Retardancy: UL 94 HF-01 flame retardant grade, effectively preventing fire spread, ensuring safe use in various scenarios.
  • Lightweight & High Strength: Density 40±8 kg/m³, lightweight but high strength, reducing product weight without sacrificing performance.
  • Clean & Eco-Friendly: Green and odorless preparation process, no chemical residues, safe and environmentally friendly.
  • Excellent Buffer Protection: Good compression performance, effectively absorbing impact and reducing vibration, protecting products from damage.
  • Superior Surface Protection: Micron-scale cell structure provides excellent surface protection, avoiding scratches on protected products.
  • Good Water Resistance: Water absorption ＜0.5%, waterproof and moisture-proof, ensuring stability in humid environments.
  • Strong Chemical Resistance: Resistant to oils, acids, alkalis and other chemicals, suitable for harsh industrial environments.
