PIB 2400 (low molecular weight polyisobutylene, MW≈2400) is a non-toxic, high-viscosity, weather-resistant saturated polyolefin, widely used in lubricant thickening, adhesives, waterproofing, and rubber modification.
What Is PIB 2400 and Its Main Properties?
PIB 2400 is a linear viscous liquid produced by cationic polymerization of isobutylene, with a molecular weight of approximately 2400. Its key properties determine its wide applicability: it has a viscosity of 15,000–25,000 mPa·s at 23℃, a flash point of ≥260℃, and a pour point of ≤-40℃. With no double bonds, it has excellent oxidation and ozone resistance, with an outdoor service life of ≥10 years. It is low-volatile and ash-free, with a sulfur content of ≤1 ppm and an acid value of ＜0.02 mgKOH/g, complying with environmental protection formulas. Importantly, it is fully compatible with mineral oil, synthetic oil, rubber, asphalt, and paraffin, making it a versatile additive for various industries, especially suitable for the high-temperature, high-humidity, and strong UV environments in Africa and South America.
What Are the Main Industrial Applications of PIB 2400?
Lubricant & Grease Additives (the largest application): Adding 3–8% PIB 2400 to gear oil and hydraulic oil can improve high-temperature oil film strength and low-temperature pumpability, resist micro-pitting, and is suitable for wind power, mining, and agricultural machinery (a rigid demand in East and West Africa). For engine oil and chain oil, it reduces high-temperature carbon deposition, extends the oil change cycle to 8,000 hours, and the viscosity loss rate is less than 5%.
Adhesives & Sealants: It is used in pressure-sensitive adhesives, hot-melt adhesives, medical adhesives, and depilatory waxes, increasing initial adhesion by 30% and aging resistance by 50%. For insulating glass and building sealants, it has good air tightness and low permeability, with a service life of ≥15 years.
Construction Waterproofing & Asphalt Modification: It is applied in roof and basement waterproofing membranes and sealants, with excellent water resistance, weather resistance, and crack resistance, and an elongation at break of ≥800%. When used for asphalt modification, it improves low-temperature crack resistance and high-temperature rutting resistance, extending road service life by 40% (popular in South American infrastructure projects).
Rubber & Plastic Modification & Personal Care: It is used in tire inner tubes, cable insulation, and rubber-plastic blending to enhance toughness, air tightness, and insulation, with a volume resistivity of ≥10¹⁴ Ω·cm. In cosmetics such as lipsticks, hair waxes, and hand creams, it is non-toxic and compliant (FDA/CE), with moisturizing, film-forming, and smoothing effects.
