Characterization: Hyperlite E-852 is a polymer polyol, which is used in a broad range of urethane foam and other applications. Properties / Applications: Hyperlite E-852 is a polymer polyol, which is used in a broad range of urethane foam and other applications. It is especially suited for rapid-demold high-resiliency (HR) foam, and is typically used in molded urethane foam for automotive seat cushions and backs. The Hyperlite E-852 polymer polyol, when blended with Hyperlite polyether polyols, produces foams with inherent stability during molding, excellent breathability characteristics, and a high level of strength, durability, and load-bearing properties. As with any product, the use of Hyperlite E-851 polyol in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability Information provided by Covestro |
