CPI : CP-4628-100

PRODUCT DESCRIPTION

CP-4628-100 is a custom-blended polyalphaolefin  (PAO) synthetic hydrocarbon, giving inertness and hydrolytic stability. This product is compatible with mineral oils and equipment designed for use with mineral oils.

CP-4628-100 (typical properties shown below) was developed with unique additive and basestock technology for improved seal performance and extended elastomer life. This is a long life lubricant, formulated especially for flooded screw compressors.

CP-4628-100 is recommended for refrigeration services due to excellent low temperature properties. Because CP-4628-100 is synthetic, it is wax-free. A low pour point prevents the lubricant congealing in refrigeration lines. A high film strength provides improved lubricity even when diluted with refrigerants.
