Description
Polyflo® 5 is a premium high-flash aromatic naphtha solvent characterized as a complex mixture of C11-C24 aromatic hydrocarbons. This ultra-high purity aromatic process oil delivers exceptional solvency power with aromatic content typically exceeding 99%, making it one of the highest-purity aromatic solvents available for demanding industrial applications. A key differentiator of Polyflo® 5 is its virtually naphthalene-free composition—the product contains no detectable naphthalene at a detection limit of 500 ppm, addressing environmental and workplace exposure concerns while maintaining superior dissolving capability. With a high flash point of 270°F minimum, Polyflo® 5 provides enhanced safety margins during handling, storage, and processing compared to lighter aromatic grades, while its controlled viscosity range (4.0-6.0 cSt @ 40°C) ensures excellent flow characteristics and efficient heat transfer in process applications. The broad carbon range (C11-C24) delivers a slow, controlled evaporation profile ideal for applications requiring extended working time, superior resin dissolution, and uniform film formation.
- Ultra-High Aromatic Purity: Greater than 99% aromatic content delivers exceptional solvency power for dissolving resins, polymers, and challenging additives.
- Naphthalene-Free: No detectable naphthalene at 500 ppm detection limit—supports environmentally conscious formulations and reduces regulatory and exposure concerns.
- High Flash Point: 270°F minimum flash point provides enhanced workplace safety and wider processing temperature margins compared to lighter aromatic solvents.
- Controlled Viscosity: 4.0-6.0 cSt @ 40°C ensures excellent flow characteristics for processing, blending, and heat transfer applications.
