Engine oils

We are offering ester type pour point depressant for low pour point engine oils.
description
t809a is a copolymer of high carbon alcohol esters. When added into oils, it can effectively reduce the pour point of lubrication oils and improves its fluidity at low temperature. It is a pour point depressant generally used for the lubricating oils.
special features
� fine pour point depressing effect for paraffin-based oil
� add 0.5 mass% into hvi 150sn base oil (the pour point not higher than -15oc), the pour point depression will be more than 15 degrees celsius
applications
used for blending various low pour point engine oils, machine oils and hydraulic oils
the dosage: 0.1-0.5%
