Polybutene-1 grade Koattro PB0800M is a semi-crystalline homopolymer, which can be used where creep and 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 can be used to improve mechanical properties at elevated temperatures. It is less compatible in blends with polyethylene but it is still easily dispersible.

It's relative slow crystalliation kinetics allows for an excellent wetting behaviour. Besides their high shear sensitive flow behaviour they remain easily dispersible also in even more incompatible polymers like thermoplastic elastomers.
