Dissolving

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.

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.
