Cellasto® MH24-65 is a high-performance microcellular polyurethane elastomer manufactured by BASF. The "65" in its grade name indicates an approximate density of 650 kg/m³, making it a higher-density, high-strength grade within the Cellasto MH24 series, primarily used for vibration-damping and cushioning components in automotive chassis and suspension systems.
Key Features
Low Compression Set: Recovers well after prolonged compression, maintaining dimensional stability.
High Volume Compressibility with Minimal Lateral Expansion: Ideal for space-constrained cushioning applications.
Excellent Mechanical Properties & Durability: High load-bearing capacity and long fatigue life.
Versatile Vibration Damping: Isolates both small-amplitude, high-frequency noise and large-amplitude, low-frequency vibration.
Resistance to Ozone, Oils, Greases & Other Aliphatic Hydrocarbons .
