Polybutene-1 DP 8510 Copolymer of butene-1 and ethylene 25087-34-7 Basell Ethylene co-terpolymers - solid (EVA, EMA) ADHESIVE >> Hot-melt SEALANT Polybutene-1 development grade DP8510 is a random copolymer of butene-1 with high ethylene content. Polybutene-1 grade DP8510 is primarily used as a blend component in hot melt adhesives (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. This polymer is also highly compatible with polypropylene due to its similar molecular structure. It is less compatible in blends with polyethylene but it is still easily dispersible. Polybutene-1 grade DP8510 meets FDA requirements in 21 CFR 175.105 for adhesives.
