(polybutene-1, poly(1-butene), PB-1) is a polyolefin or saturated
polymer with the chemical
- Polybutylene is a form
of plastic resin that was used extensively in the manufacture of
water supply piping
from 1978 until 1995. Due to the low cost of the material and ease
of installation, polybutylene piping systems were viewed as "the
pipe of the future" and were used as a substitute for traditional
- Polybutylene has a
semi-crystaline structure, meaning its constituent atoms are bonded
into a regular structure
only over small areas, with the rest of the material bonding in an
- Polybutylene resins
are semicrystalline highly isotactic thermoplastics derived from the
polymerization of butene -1 monomer with or without other alpha -
olefin monomers utilizing Zieglar - Natta type of catalysts.
- Polybutene is widely
used in lubricant for modifying / improving the viscosity of the
lubricant formulation to the desired final viscosity.
- Polybutene acts as a
Polymer extender , Plasticiser, Tackifier and Wetting agent.
- Polybutene can improve
the melt flow in crystal polystyrene, better than mineral oil while
maintaining higher strength and heat deflection temperature.
- Polybutenes can be
used to modify the Asphalt that can be used in road construction.
The addition of polybutenes to asphalt give improved flexibility in
low temperature, better weathering and an excellent aggregate/binder
- For a wide variety of
vulcanized elastomers like natural rubber, butyl rubber,
polyisoprene, PB, ethylene-alpha olefin rubber and SBR, KVIS
polybutenes are used as extenders and plasticizers.
- Polybutylene based
blends are suitable as the peel seal coating layer of lid stocks
which may be used as the lid
or top web for the containers made of polypropylene and
- Polybutene consumption
is most influenced by the market for fuel and oil additives, which
in turn, is a function of lubricant sales. Lubricant sales in the US
are growing at slightly better than 1%/year.
- Highly reactive
polyisobutylene (HR-PIB) competes with conventional polybutenes in
the fuel additives market. In this sector, it is growing at 1 to
2%/year, while conventional polybutenes are flat to declining.
