Polybutene-1 DP8911M LyondellBasell Polybutylene

Product Description

Polybutene-1 grade DP8911M is a random copolymer of butene-1 with high ethylene content, containing free organic peroxide additives.
DP8911M is primarily used as a blend component in hot melt adhesive (HMA) formulations and sealant compounds, in order to increase open time and maintain mechanical integrity at higher temperatures (higher shear adhesion failure temperature or SAFT). It can be used in combination with a wide variety of non-polar resins and waxes.
The presence of free organic peroxides in polybutene-1 grade DP8911M allows the reduction of melt viscosity in elevated temperature processing. The rate of further peroxide cracking depends on the time and temperature of processing. To achieve 100% utilization of the residual peroxide, a temperature of 180°C or higher is usually applied for at least 30 minutes. In order to achieve the target viscosity at 180°C, the product should be kept in a closed container during processing, to minimize the loss of the organic peroxide.
Food law compliance information about this product can be found in separate product documentation.
