Polybutene-1 PB 0300M

About
Polybutene-1 grade PB 0300M is a semi-crystalline homopolymer, which is used where creep, 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 is used to improve mechanical properties at elevated temperatures. It is less compatible in blends with polyethylene but it is still easily dispersible . It forms a 2 phase structure which is the basis of the seal peel technology for easy-opening packaging applications. 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. This product is not intended for use in medical and pharmaceutical applications.&&
