I. Introduction to ExxonMobil Isopar E
Isopar E is an isoparaffinic solvent oil with a distillation range of 115~140°C, a flash point of 7°C, a density of 0.723g/cm³, a viscosity of 0.85mm²/s(25°C), an aromatic content of <0.005%, a relative evaporation rate of 1.86（n-BuAc=1）, a KB value of 29, a bromine number of <5mg/100g, a surface tension of 21mN/m(25°C), and a refractive index of 1.405(20°C). The product is packaged in iron drums, with a specification of 145 kilograms/drum.
Isopar E can be used as an industrial cleaning fluid (for cleaning electronic and electrical equipment, maintenance cleaning), consumer product solvent (for aerosol insecticide solvents, lighter fluid, polish solvent), metalworking cleaning and rust preventive oil, electrostatic copier diluent, plastic polymerization reaction co-solvent and carrier, organosol, coatings, inks, electronic cleaning, stamping oil, lighter fuel oil, hand warmer fuel oil, etc.
The advantages of Isopar E include: almost odorless, narrow distillation range, low viscosity, compatibility with most product surfaces, easy evaporation, and suitability for indirect food contact equipment.

III. Precautions
1. ExxonMobil environmental solvent drums have an ExxonMobil anti-counterfeiting mark on the lid and an anti-counterfeiting barcode on the drum surface. Identify the brand to avoid counterfeits.
2. Environmental solvent oil should not be stored upright outdoors to prevent contamination by moisture and debris.
3. For indoor storage, place upright with the drum face up for easy extraction.
4. Tighten the lid to keep the drum sealed.
5. Do not place flammable materials nearby; open flames are strictly prohibited, and do not bring ignition sources near the drum.
6. Store flammable specialty oils or chemical solvents separately and mark with flammable signs.
