Polybutylene (polybutene-1, poly(1-butene), PB-1) is a polyolefin or saturated polymer with the chemical formula (C4H8)n. It should not be confused with polybutene, a low molecular weight oligomer.
Polybutylene is produced by polymerisation of 1-butene using supported Ziegler-Natta catalysts. PB-1 is a high molecular weight, linear, isotactic, and semi-crystalline polymer. PB-1 combines typical characteristics of conventional polyolefins with certain properties of technical polymers.
PB-1, when applied as a pure or reinforced resin, can replace materials like metal, rubber and engineering polymers. It is also used synergistically as a blend element to modify the characteristics of other polyolefins like polypropylene and polyethylene. Because of its specific properties it is mainly used in pressure Plumbing System, flexible packaging, water heaters, compounding and hot melt adhesives.
The PB-1 industry is highly concentrated. There are only four manufacturers engaged in the industry presently, including LyondellBasell, Mitsui Chemicals, Ylem Technology, Shandong Hongye Chemical. LyondellBasell is the largest producer with an output of 61171 MT in 2016. Mitsui Chemicals is the sole manufacturer in Japan and mainly provides PB-1 to pipe industry.
