Pour Point Depressant Polymethacrylate (PMA)

Chemical Name: Polymethacrylate (PMA)
CAS Reg. No.: 50867-55-5

1. DESCRIPTION
The product is a PMA type light color highly active additive. It has favorable solidifying point depressing effect with a few dosages, and fine low temperature property.
It is able to improve the viscosity index, and possesses certain viscosifying action as well.

2. APPLICATIONS
The product is used primarily for blending of aircraft hydraulic oil, hydraulic transmission oil, gear oil, low pour point hydraulic oil, and multi-grade engine oil. These are highly shear stable polymers that provide efficient thickening along with pour point.
It is recommended that, widely used universal pour-point depressant. When 0.5% is added into Fushun 150SN base oil, solidifying point depressing is at 14-16℃, 0.8 - 1% OCPA or 0.6%-0.8% is saved, and the VII is increased by 8.
The oil product has extra fine low temperature property.

3. SUGGESTED DOSAGE
The recommended dosage is from 0.2% to 0.5% for solidifying point depressing.
