Koattro PB M 8911M
About this product
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.
This grade is not intended for medical and pharmaceutical applications.
