Polybutadiene is a synthetic rubber that is a polymer formed from the 
polymerization of the monomer 1,3-butadiene. It has a high resistance to 
wear and is used especially in the manufacture of tires. It has also been 
used to coat or encapsulate electronic assemblies offering extremely high 
electrical resistivity. 
 
Polyisobutylene is a synthetic rubber, or elastomer. It is special because it 
is the only rubber that is gas impermeable; it is the only rubber which can 
hold air for long periods of time. Polyisobutylene, sometimes called butyl

rubber is a vinyl polymer, and is very similar to polyethylene and 
polypropylene in structure. 
 
Polybutylene (PB-1) is a high molecular weight, linear, isotactic, and semi-
crystalline polymer. PB-1 replaces materials like metal, rubber and 
engineering polymers. Because of its specific properties it is mainly used in 
pressure piping, flexible packaging, water heaters, compounding and hot 
melt adhesives.
