Polyisobutene Succinimide Water Resistant, Ozone Resistant And Resistant To Aging Aug 03, 2017

Polyisobutene Succinimide Properties:

01 Properties of Polyisobutene Succinimide

Polyisobutene Succinimide is a colorless, tasteless, non-toxic isobutylene homopolymer. Due to the different preparation methods and process conditions, the molecular weight of Polyisobutene Succinimide varies over a wide range. Most of the molecular weight of the product to reach 10000 ~ 200000 or more from the viscous liquid into a sticky semi-solid, and then transition to the rubber-like elastomer. Polyisobutene Succinimide is resistant to acids, alkali, salt, water, ozone and aging resistance, and has excellent air tightness and electrical insulation. It is very compatible with wax, asphalt, polyethylene and so on.

Properties of High Molecular Weight Polyisobutene Succinimide

The high molecular weight Polyisobutene Succinimide is a typical saturated linear polymer whose head group is -CH3 and the tail group is -CH2-C = CH2 or -CH = C-CH3. Its heat resistance, light resistance, good resistance to ozone aging, with the ideal chemical stability. At room temperature, the dilute alkali and concentrated acid, alkali, salt, the role of stability. At higher temperatures, the polymer Polyisobutene Succinimide still has excellent water resistance and air tightness, and the dielectric properties are excellent. High molecular weight Polyisobutene Succinimide is usually solid.

Low molecular weight Polyisobutene Succinimide

Low molecular weight Polyisobutene Succinimide (abbreviated as isoprene) is a colorless, odorless, non-toxic, viscous object that is used in petroleum additives, adhesives, chewing gum additives, and blends with other polymers. Oligomeric isobutylene in many areas of the application depends mainly on its viscosity behavior, thermal stability and electrical insulation, etc., oligoisobutylene has a good heat, oxygen, ozone, UV, acid, alkali and other properties , Its expansion coefficient is small, no dielectric harmful substances, excellent electrical insulation.

Low isobutylene is Newtonian fluid with high viscosity index. Applicable to oil viscosity, 100% cracking at high temperatures without residue, can be used as ashless additives. Oxygen isobutylene and polymer materials with good compatibility, and the general non-polar material has good compatibility, with low temperature dispersion and high temperature cleanliness. Low molecular weight Polyisobutene Succinimide is usually viscous liquid or semi-solid.

04 Properties of ordinary low molecular weight Polyisobutene Succinimide

The performance characteristics of ordinary low molecular weight Polyisobutene Succinimide are: the content of methylvinylidene at the end of the chain is low. Because of its low content, in the preparation of lubricants ash-free dispersant can only use the "chlorination route" and "catalytic hot addition route", resulting in "chlorination route" although can greatly improve the Polyisobutene Succinimide (PIB) and Malay Acid anhydride (MA) reaction, but the final product of chlorine content is higher, more and more users are welcome; and "catalytic hot addition route" due to varying degrees of reaction time is long, low conversion rate, the corresponding increase in cost And other issues are limited.

05 Polyisobutene Succinimide performance

Polyisobutene Succinimide is a colorless, tasteless, non-toxic isobutylene homopolymer. Due to the different preparation methods and process conditions, the molecular weight of Polyisobutene Succinimide varies over a wide range. Most of the molecular weight of the product to reach 10000 ~ 200000 or more from the viscous liquid into a sticky semi-solid, and then transition to the rubber-like elastomer. Polyisobutene Succinimide is resistant to acids, alkali, salt, water, ozone and aging resistance, and has excellent air tightness and electrical insulation. It is very compatible with wax, asphalt, polyethylene and so on.
