Dissolving Method & Viscosity Levels
Polymers should be dissolved under high agitation in oil at 100°C – 160°C for 3-6 hours until all solids have been dissolved. Treat rates of 6-10% will be required depending upon the viscosity grade required and the base oil used. Use with suitable PPD. Consult the CHEMPOL technical department for specific recommendations.
- 10% of CHEMPOL P25 in Base Oil SN500 produces a Viscosity of 1900 – 2000cst @ 100°C.
- 11.5% of CHEMPOL P25 in Base Oil SN 150 produces a Viscosity of 1800 – 1900 Cst @ 100°C.
It is generally recommended to make Liquid VI with SN150 Base Oil for a better low pour point while formulating Motor Oils. The index of the oil will be increased based on the grade of the oil used.
Dissolving time
Approx. 3 -6 hours @ 120°C.
Safety, Handling and Storage
Wear a suitable dust mask & gloves when handling polymers. Avoid storing pellet-type polymers >30°C for prolonged periods, and avoid direct sunlight.
