Polybutene-1 grade Koattro DP 0400M is a semi-crystalline homopolymer, which can be used where creep, environmental stress crack resistance and elevated temperature performance are key requirements.
This polymer is highly compatible with polypropylene due to its similar molecular structure. It is less compatible in blends with polyethylene but it is still easily dispersible.
Its relative slow crystalliation kinetics allows for an excellent wetting behaviour. Besides its high shear sensitive flow behaviour it remains easily dispersible, also in even more incompatible polymers like thermoplastic elastomers.
