| Polybutene-1 grade DP8510M is a random copolymer of butene-1 with high ethylene content. This product is primarily used in hot melt adhesive formulations and to improve rheological properties in blends. DP8510M is highly compatible with polypropylene due to its similar structure but less compatible in blends with polyethylene, but still easily dispersable. Its relatively slow kinetics of crystallization allow for an excellent wetting behavior. Its high shear-sensitive flow behavior means that it remains easily dispersable also in even more incompatible polymers like thermoplastic elastomers. This product is not intended for use in food contact, medical and pharmaceutical applications.&& |
