PIB 2500
RB Products, Inc. manufactures and supplies PIB 2500, a conventional polyisobutylene valued for its purity, chemical stability, and versatility across industrial formulations. We serve domestic and international clients with a diverse line of conventional and high reactive polyisobutylene products, backed by consistent quality and responsive service. If your business sources PIB 2500 for adhesives, lubricants, or sealant applications, our team can help you find the right grade and get your order moving.
What Is PIB 2500?
PIB 2500 is a conventional polyisobutylene, a colorless, chemically inert liquid produced through the controlled polymerization of isobutylene. Polyisobutylene is known for high resistance to oxidation, ultraviolet light, and many organic solvents, maintaining chemical stability and flexibility even under high temperatures.
PIB 2500 is non-drying and highly resistant to oxidation and photodegradation. As a polybutene, it is non-toxic and leaves no residue when volatilized or thermally decomposed, making it a clean, dependable choice for formulations where purity and non-reactivity are priorities.
Key Properties of PIB 2500
PIB 2500 offers the property profile formulators expect from a mid-to-high molecular weight conventional polyisobutylene:
| Property | Benefit |
|---|---|
| Colorless & Odorless | Clean appearance for sensitive formulations |
| Chemically Inert | Low reactivity with contacting materials |
| Non-Drying | Maintains tack and flexibility over time |
| Oxidation & UV Resistant | Stable through long-term storage and shelf life |
| Non-Toxic | Leaves no residue when volatilized or thermally decomposed |
| Excellent Moisture Resistance | Strong barrier performance in sealant and coating applications |
