SDT806A is the copolymer of fumarate and vinyl acetate, which has good low-temperature flow ability and excellent effect in dropping condensate. It can effective inhabit wax component in lubricant to form network structure at low-temperature, therefore, it can effective drop pour point of lubricant.
