Koattro PB M 8911M

Polybutene-1 grade Koattro PB M 8911M is a random copolymer of butene-1 with high ethylene content.

Koattro PB M 8911M is primarily used as a blend component in woodworking and assembly hot melt adhesive
formulations. It can be used in combination with a wide variety of non-polar resins and waxes and maintains
good cohesive strength of the HMA and higher Shear Adhesion Failure Temperature (SAFT).

Koattro PB M 8911M is also used to improve rheological properties in blends. It is highly compatible with
polypropylene due to its similar structure. Koattro PB M 8911M is less compatible but still easily dispersible in
blends with polyethylene. Its relatively slow kinetics of crystallization allow for an excellent wetting behavior. Its
high shear-sensitive flow behavior means that it remains easily dispersible also in even more incompatible
polymers like thermoplastic elastomers.

Koattro PB M 8911M can also be used in Melt Blown and Spunbond applications offering reduced bonding temperature and improved softness.
