Classification of Polyisobutylene

Different molecular weights: low, medium and high molecular weight polyisobutylene

High and low mole fractions of terminal vinyl groups: high reactive polyisobutene and low reactive polyisobutylene

Different degrees of hygiene: food-grade polyisobutylene and technical-grade polyisobutylene

Different polymerization processes: bulk polyisobutene and solvent polyisobutene

The sources of raw materials are different: pure isobutene polyisobutene and mixed carbon tetrapolyisobutene catalysts are different, aluminum-based polyisobutene and boron-based polyisobutene.

There are two commercially available polymers not commonly referred to as polyisobutylene. One is butyl rubber, which is a copolymer of isobutylene and 1%-3% isoprene. Butyl rubber competes with polyisobutylene in adhesives, sealants, fillers, etc. The other is polybutene-1. The performance of polybutene-1 is very similar to that of polyisobutene at low molecular weight, but the performance difference is obvious at medium and high molecular weight. 1 Rubber-based adhesives and sealants.

Polyisobutylene can be used in adhesive and sealant formulations. Its consumption accounts for about 13%-15% of the total global consumption. Polyisobutylene is especially suitable for environments that are sensitive to moisture and require insolubility in water. Usually low molecular weight polyisobutylene is used as a tackifier or plasticizer, while medium and high molecular weight polyisobutylene is used to adjust elasticity, extensibility, cohesion and air tightness; polyisobutylene products have better aging resistance than rubber-based products, and the stickiness lasts , can be used on surfaces that other polymers cannot adhere to.

Properties of Polyisobutylene

01 Qualities of polyisobutylene
Polyisobutylene is a colorless, odor-free, non-toxic isobutylene homopolymer. As a result of different preparation techniques and procedure problems, the molecular weight of polyisobutene differs in a vast array. When the molecular weight of many items reaches 10,000-200,000, it will certainly change from a viscous fluid to a sticky semi-solid, and afterwards to a rubber-like elastomer. Polyisobutylene is resistant to acid, antacids, salt, water, ozone and aging, and also has exceptional air rigidity and also electric insulation. It has great compatibility with wax, asphalt, polyethylene, etc

02 Features of high molecular weight polyisobutylene

High molecular weight polyisobutylene is a regular saturated linear polymer, its head team is -CH3, and its tail group is -CH2-C= CH2 or -CH= C-CH3. It has great warmth resistance, light resistance and ozone aging resistance, as well as has perfect chemical security. At space temperature, it is stable against water down antacids and also focused acid, antacid and also salt. Polymer polyisobutylene still has excellent water resistance and airtightness at higher temperature levels, as well as its dielectric properties are fairly exceptional. High molecular weight polyisobutylene is generally in the solid state.
