It is characterized by low moisture absorption, excellent electrical properties, and good chemical resistance, mechanical strength, and heat resistance. Sigma-Aldrich (2) Physical Form. Polybutylene is composed of linear chains having an isotactic arrangement of ethyl side groups along the chain backbone. In guaranteed quality, at stable prices, packed appropriately for transportation and delivered punctually. All four butenes are gases at room temperature and pressure. In cling masterbatches, polybutene acts as a cling agent to impart a slight stickiness to plastic food wraps. In extreme cases, this stress-activated chemical "corrosion" can lead to perforation and leakage within a few years, but it also may not fail for decades. PB-1 disperses easily in other polyolefins, and at low concentration, acts as processing aid reducing torque and/or increasing throughput.
