MIC Corrosion: How Can Microorganisms Eat Holes in a Metal? It is used to make up for the shortcomings of polyvinyl acetate hardening when cold, and the population is too soft after saliva, and the amount of polyvinyl acetate accounts. Peelable easy-to-open packaging where PB-1 is used as blend component predominantly in polyethylene to tailor peel strength and peel quality, mainly in alimentary consumer packaging and medical packaging. The randomness of these components along the chain make two polybutene molecules difficult to pack together nicely, thus lowering the melting point of the compound. It is also used synergistically as a blend element to modify the characteristics of other polyolefins like polypropylene and polyethylene.
