Product Details
Polyisobutylene (PIB): The Essential Component for High-Tier Lubricants
Available in High-Reactive (HR-PIB) and Conventional Grades
Chemost is a leading manufacturer and global supplier of Polyisobutylene (PIB), a key synthetic hydrocarbon polymer used extensively in the production of lubricants, greases, and chemical intermediates.
As a non-polar, hydrophobic, and completely ashless polymer, PIB is the preferred choice for factories and wholesalers seeking to improve the viscosity-temperature relationship of oils or to synthesize high-performance dispersants.
1. Understanding PIB: Molecular Weight & Reactivity
Polyisobutylene is categorized by two primary factors: its Molecular Weight and its Chemical Activity.
Reactivity Levels
Conventional PIB: Contains a lower percentage of terminal double bonds. It is primarily used as a physical additive for thickening and shear stability.
Highly Reactive PIB (HR-PIB): Features a terminal vinylidene content typically exceeding 80%. This high "activity" allows for efficient chemical functionalization.
The Synthesis Pathway
HR-PIB is the essential feedstock for the "Thermal Adduct" process:
- HR-PIB + Maleic Anhydride PIBSA (Polyisobutylene Succinic Anhydride).
- PIBSA + Polyamines PIBSI (Polyisobutylene Succinimide / Ashless Dispersant).
2. Technical Specifications & Common Grades
We provide a range of grades to suit different blending requirements. Below are the common molecular weights utilized by our B2B partners:
Grade | Molecular Weight (Mw) | Kinematic Viscosity @ 100°C (mm2/s) | Primary B2B Application |
|---|---|---|---|
PIB 680 | 680 ± 50 | 25 – 35 | Synthetic base fluid, metalworking |
PIB 950 | 950 ± 50 | 190 – 240 | Most common grade for PIBSA/PIBSI synthesis |
PIB 1000 | 1000 ± 50 | 250 – 310 | High-performance dispersant feedstock |
PIB 1300 | 1300 ± 50 | 580 – 650 | 2-Stroke engine oils, tackifiers |
PIB 2400 | 2400 ± 100 | 4200 – 4800 | Gear oils, heavy-duty lubricants, greases |
3. Key Advantages in Lubricant Formulation
Ashless Viscosity Index Improver (VII): Unlike olefin copolymers (OCP), PIB is 100% ashless, preventing deposit formation in high-temperature zones.
Excellent Shear Stability: High molecular weight grades offer superior "Stay-in-Grade" performance for automotive and industrial gear oils.
Oxidation Stability: Due to its saturated hydrocarbon backbone, PIB resists oxidative thickening and sludge formation.
Tackiness & Adhesion: Higher molecular weight grades (PIB 2400+) act as tackifiers, improving the "cling" of lubricants to moving metal parts.
Clean Depolymerization: At extremely high temperatures, PIB decomposes into gaseous monomers without leaving carbonaceous residues, making it ideal for 2T engine oils.
4. Application Guidance & Use Cases
Manufacturing Use Cases
- Dispersant Factories: Utilize HR-PIB 950/1000 to produce high-purity ashless dispersants for crankcase oils.
- Lubricant Blending Plants: Use PIB 1300/2400 as a cost-effective thickener and VI improver for industrial gear oils (ISO VG 220, 320, 460).
- Grease Manufacturers: Incorporate PIB into wire rope or open gear greases to enhance water washout resistance and adhesion.
Compatibility with Other Additives
PIB is chemically inert and highly compatible with:
- Sulfonates & Phenates: No interference with detergent performance.
- ZDDP: Synergistic protection in hydraulic and engine oils.
- Antioxidants: Can be easily stabilized with Aminic or Phenolic antioxidants.
5. Quality Control & Documentation
Chemost ensures that every shipment meets the rigorous standards of the international lubricant market. We provide a complete document package to facilitate your quality audit and customs clearance:
- TDS (Technical Data Sheet): Detailed physical/chemical parameters.
- MSDS (Material Safety Data Sheet): Global GHS standard safety information.
- COA (Certificate of Analysis): Batch-specific testing results (Viscosity, $M_w$, Color, Flash Point).
Frequently Asked Questions (FAQ)
Q: What is the main difference between PIB 950 and PIB 2400?
A: The difference lies in viscosity and application. PIB 950 is thin enough to be used as a chemical feedstock or a light thickener, while PIB 2400 is extremely viscous and is used to provide heavy film strength in gear oils and greases.
Q: Why is "High Reactivity" (HR-PIB) important for manufacturers?
A: HR-PIB contains more "active" ends (vinylidene groups). This results in a faster reaction time and higher conversion rates when synthesizing PIBSA, leading to less waste and a higher-quality final dispersant.
Q: How do you handle the logistics for high-viscosity grades like PIB 2400?
A: High-viscosity grades are typically heated during loading. We recommend that factories have heating facilities (steam or electric) for easier unloading of 200L drums or IBCs.
Q: Is your PIB compatible with PAO base oils?
A: Yes, PIB is fully miscible with Polyalphaolefins (PAO) and all mineral-based groups (I, II, and III).
