The bio-based polyols from Hug Chem listed below are effective alternatives to hydroxyl functional polybutadiene for use in polyurethane potting compounds. They offer superior low temperature performance, low water solubility and moisture vapor transmission, excellent thermal stability, and good electrical properties.
The engineered polyols that provide a flexible hydrophobic backbone with a low glass transition temperature for applications where increased hydrophobicity and low temperature performance is required. And the other type of engineered bio polyol with lower functionality that provides a slightly softer cured product where flexibility is advantageous.
Key Benefits
• Superior low and high temperature performance
• Hydrophobic structure with good chemical and moisture resistance
• Very low moisture vapor transmission rates
• Good electrical properties
• Comparable performance to petrochemical polyols, but with high renewable content
• Produced from well-established, readily available natural feedstocks
FHF series is polyol to develop hard floor coating material intended to use with crude MDI as hardener. This series give hardness and elongation required for floor coating, and also enable to stand in hot and humid conditions.
