Polyisobutylene (PIB), also known as Polyisobutene, is a synthetic polymer produced by polymerizing isobutylene monomers. With the chemical formula (C₄H₈)n and CAS No. 9003-27-4, PIB is a colorless, odorless, non-toxic polymer with excellent chemical stability, flexibility, and impermeability.
Depending on molecular weight and viscosity grade, Polyisobutylene is available in different grades such as PIB 400, PIB 680, PIB 1300, and PIB 2400, which are widely used in lubricant additives, adhesives, sealants, plastic modification, electrical insulation materials, packaging films, and chewing gum bases.

Products Description
Polyisobutylene (PIB) is a versatile elastomer that belongs to the class of polyolefins. It is a high molecular weight polymer composed of repeating units of isobutylene. PIB is typically a viscous liquid or a soft solid with rubber-like properties. It is chemically inert, non-toxic, and resistant to heat, moisture, and chemicals.
As a leading global supplier, we deliver certified Polyisobutylene PIB chemical raw materials compliant with REACH, ROHS, ISO, and other international standards.

Polyisobutylene Grades: PIB 400 vs PIB 680 vs PIB 1300 vs PIB 2400:
Different PIB grades are mainly distinguished by molecular weight and viscosity.
| Grade | Characteristics | Typical Applications |
|---|---|---|
| PIB 400 | Low viscosity, good flowability | Lubricant additives, fuel additives |
| PIB 680 | Medium viscosity with good balance | Adhesives, sealants, oil additives |
| PIB 1300 | Higher molecular weight and stronger tack | Hot melt adhesives, coatings |
| PIB 2400 | High viscosity and excellent sealing properties | Sealants, rubber modification, specialty adhesives |
Main Applications of Polyisobutylene PIB
Polyisobutylene PIB Uses:
1. Lubricant Additives
Polyisobutylene is used in lubricants to improve viscosity, stability, and wear protection.
2. Adhesives and Sealants
It is an important material for adhesives and sealants because it provides strong tack and good durability.
3. Packaging Materials and Stretch Films
It is added to packaging materials and stretch films to improve flexibility, cling, and moisture resistance.
4. Electrical Insulation Materials
It is suitable for electrical insulation because it has good insulating properties and resists moisture.
5. Rubber and Plastic Modification
PIB is used to modify rubber and plastic products so they become more flexible and durable.
6. Chewing Gum Base
Food-grade polyisobutylene is also used in chewing gum bases because it is safe, flexible, and stable.
Final Application of different grades
| Application | Recommended Grade |
|---|---|
| Lubricant additives | PIB 400 / PIB 680 |
| Adhesives | PIB 680 / PIB 1300 |
| Sealants | PIB 1300 / PIB 2400 |
| Stretch film | PIB 400 / PIB 680 |
| Electrical insulation | PIB 1300 / PIB 2400 |
