In the realm of polyurethane production, the shift towards sustainable materials has become increasingly prominent. HUG CHEM, a China - based manufacturer, introduces FH - 1628, a bio based polyol that serves as a key component in various polyurethane products, with a particular focus on polyurethane sealants. This product stands out for its unique composition and versatile applications, making it a notable option in the industry.
FH - 1628 is a high molecular weight, primary hydroxyl terminated diol. It is often used in combination with the FH series of bio based polyols, forming a reliable base for the manufacturing process. This polyol finds its utility in the production of polyurethane shoe soles and fascia products, demonstrating its adaptability across different product lines. Beyond these, it is also applicable in the creation of a wide range of sealants and elastomers, showcasing its multifunctional nature.

FH - 1628 plays a significant role in the production of sealants. Its chemical properties contribute to the formation of sealants that can effectively perform under various conditions. The bio based nature of the polyol adds to the appeal of these sealants, aligning with the growing demand for environmentally friendly products in the market.
In the manufacturing of elastomers, FH - 1628 proves to be a valuable ingredient. Elastomers require specific characteristics to ensure flexibility and durability, and this polyol helps in achieving those properties. The inclusion of this bio based polyol in elastomer production offers a sustainable alternative without compromising on the functional aspects of the end product.
Proper storage and transportation are crucial to maintaining the quality of FH - 1628. It should be stored under dry conditions with the temperature kept below 60°C. This ensures that the polyol remains stable and retains its intended properties. For transportation and storage, the product is available in 200kg non - returnable steel drums and 1000kg IBC tanks made from HWHDPE, providing suitable options based on quantity requirements.
FH - 1628 is part of the raw materials used in the preparation of various polyurethane products. It is important to note that polyurethanes are organic materials and are considered combustible, requiring careful handling during all stages of use.
