Description

Baygal K 390 is a high-performance, moisture-sensitive polyurethane raw material, specifically a polyether polyol, identified by CAS NO 75284-89-8. This product is engineered to deliver consistent reactivity and processing characteristics, which are critical for formulating stable and reliable polyurethane systems. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producers of flexible and rigid foams, who require a dependable polyol component for their formulations.

Application

• Formulation of high-resilience and conventional flexible polyurethane foams.
• Production of rigid polyurethane foams for thermal insulation applications.
• Key component in coatings, adhesives, sealants, and elastomers (CASE) for enhanced flexibility and durability.
• Manufacturing of microcellular elastomers for automotive and industrial parts.
• Used in the synthesis of prepolymers for specialized polyurethane systems.
• Base material for creating sound-dampening and vibration-absorbing materials.

Quality Control

Our Baygal K 390 is produced under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot undergoes comprehensive analytical testing, including hydroxyl value, viscosity, and water content determination, to meet precise technical specifications. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from heat sources and incompatible materials.
