What is Polybutene?

Polybutene (PB) is a high molecular inert polymer, which is generally polymerized by butene. Together with polypropylene as well as polyethylene are frequently utilized plastic products. Polybutene is primarily used as pipeline wall surface product for pipes, hot water pipes and home heating pipelines.

Polybutene Property

density 0.91 g/mL at 25 °C(lit.)
form pellets
OdorData not available.
Stability:Stable. Incompatible with strong oxidizing agents.


Uses of Polybutene

While polybutene formulations might vary in the molecular weight of the polymer, polybutene describes relatively reduced molecular weight polymers that are fluid at space temperature and also pressure. Polybutene is usually made use of as a chemical intermediate in plasticizers, adhesives, gas additives and also sealants. Although polybutene is located in paints for homes such as bond, rust as well as water resistance, it is likewise often used in the solution of cosmetics such as lipstick.

Preparation Method of Polybutene

A method for producing polybutene, comprising: selectively hydrogenating diolefins in a C4 hydrocarbon component produced by a refinery involved in cracking crude oil or a naphtha cracking center, simultaneously performing an isomerization reaction of 1-butene into 2-butene, and then separating an isobutene raw material by fractional distillation; and polymerizing the isobutene raw material obtained by the fractional distillation.

High Molecular Inert Polymer

Polybutene (Polybutylene, PB) is a high molecular inert polymer, which is mainly polymerized by butene, as well as is a high molecular homopolymer. Compared to various other polyolefins:
1. Inflexible.
2. Higher tensile stamina.
3. Excellent warmth resistance.
4. Anti-chemical rust In oil, cleaning agent and various other solvents, it will certainly not be fragile like various other plastics such as HDPE. It will only end up being fragile under solid oxidizing agents such as 98% focused sulfuric acid.
5. Exceptional creep resistance.
6. It has the very same wear resistance as ultra-high molecular weight polyethylene.
