Описание материалов:
Polybutene-1 grade DP 8220M is a random copolymer of butene-1 with medium ethylene content.
This grade is highly compatible with polypropylene due to its similar molecular structure, and it is used to modify the sealing behavior of PP-based films - a typical example is its use to reduce the seal initiation temperature of BOPP sealing layers.
Its relatively slow kinetics of crystallization allow for an excellent wetting behavior. Its highly shear-sensitive flow behavior means that it remains easily dispersible also in even more incompatible polymers like thermoplastic elastomers.
Food law compliance information about this product can be found in separate product documentation.
