LyondellBasell Koattro PB M 8510M Polybutene Random Copolymer
Categories:	Polymer; Thermoplastic; Polybutene
Material Notes:	Polybutene-1 grade Koattro PB M 8510M is a random copolymer of butene-1 with high ethylene content. Koattro PB M 8510M 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 8510M is also used to improve rheological properties in blends. It is highly compatible with polypropylene due to its similar structure. Koattro PB M 8510M 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 8510M can also be used in Spunbond applications offering reduced bonding temperature. This grade is not intended for medical and pharmaceutical applications. Status: Commercial – Active Availability: Africa-Middle East; Asia-Pacific; Australia and New Zealand; Europe; North America; South & Central America Application: Carpet Backing; Hot Melt Adhesives; Polymer Modifier; Sealants Market: Compounding; Textile Processing Method: Extrusion Coating; Melt Blown; Spunbond Attribute: Extended Open Time; Good Thermal Stability; High Filler Loading Capability Information provided by LyondellBasell.
