Polymer Additites for Water Spray Off & Shear Stability :
Functional Product Offers a wide Range of quick dissolving polymers to enhance the properties such as Water Spray off & Shear Stability
 
Polymer Additives for Greases :

Polymer added during the cooling stage:

FUNCTIONAL V-207 is a copolymer based on ethylene and propylene. FUNCTIONAL V-207 is rapidly dissolving powdered polymer, specifically designed for use in greases. Unlike pre-dissolved polymers, the absence of diluent oil permits complete formulating flexibility. Greases made with FUNCTIONAL V-207 have better mechanical stability than those using polymers designed for applications like motor oil.

Functional V – 207 should be dissolved in suitable Base oil to prepare a VI improver. The Finished VI Improver should be incorporated into the batch right after the addition of the cooling oil to allow sufficient time (1 -3 hrs depending on the batch size) and high enough temperature for dissolving.

 

Polymer added during the reaction stage:

FUNCTIONAL V-4020 is rapidly dissolving pellet polymer, specifically designed for use in greases. The V- 4020 interacts with the grease soap matrix and greatly boosts the soaps performance. Unlike pre-dissolved polymers, the absence of diluent oil permits formulating flexibility and does not alter customary manufacturing processes for grease. Greases made with FUNCTIONAL V-4020 have better mechanical stability than those using polymers designed for applications like motor oil.

FUNCTIONAL V-4020 is added to the grease at the initial reaction stage. The base oil should be charged in the kettle at 65 C. Then the hydroxystearic acid and V-4020 should be combined and heated to 85 C and recirculated. The lithium hydroxide and water slurry should be added and held for 90 minutes Heat to 205 C for 20 minutes. Turn off heat and slowly add cooling oil. Mill grease.
