Polyisobutylene (PIB), also known as polybutene, is a synthetic, non-toxic, water-white viscous liquid polymer with excellent flexibility, tackiness, and water-repellency, used in various applications like adhesives, lubricants, and sealants. 

“PIB-1300” (sometimes called Polyibutene 1300) is a medium-molecular-weight grade of polyisobutylene. It’s a viscous, non-volatile, non-drying synthetic polymer used in many industrial applications. ✅ Common Applications of PIB-1300

PIB-1300 is used because of its stability, tackiness, and compatibility with many other materials. Some of its uses include:

• Lubricants & Greases: as a thickener, viscosity modifier, or additive for enhanced stability. 

• Adhesives & Sealants: tackifier, to improve adhesion and flexibility. 

• Oil Additives / Dispersants: in engine oils, fuel detergents, etcCosmetics & Personal Care: used as film formers, gloss agents, and to improve texture / application of creams, lip glosses etc. 

• Hydraulic / Gear Oils, Metal Working Fluids: helps in viscosity indexing, reducing oil evaporation & improving service life. 

• Sealant / Coating / Rubber applications, where flexibility, adhesion, and weather resistance are required. 

⚙️ Advantages & Limitations

Advantages:

• Very good thermal and oxidative stability. 

• Resistant to moisture, non-volatile (won’t evaporate under normal conditions). 

• Compatible with many additives and base oils. Good shear stability. 

Limitations:

 

• Being synthetic polymer, its cost is higher than some simpler oils / resins.

• Pour point is modest (can get stiff / viscous at lower temps).

• Needs correct handling (avoid high heat, contamination).

 What is PIB-950

• PIB-950 is a grade of polyisobutylene (PIB) — a viscous, synthetic polymer.

• “950” refers roughly to its molecular weight/viscosity class. It’s a mid-/moderate weight PIB, not very low, not extremely high.

• It’s a non-drying, non-volatile, hydrophobic liquid polymer. Chemically stable, inert to many chemicals, with good resistance to oxidation, UV, aging
