Ethylene-propylene Copolymer

EPDM is applied to lubricant viscosity index improvers.

J-0050 (J-0043) has a strong ability to increase density and a good shearing stability. This grade is mainly used to mix moderate or higher quality lube oils;
J-0030 has an excellent shearing stability and capability of increasing density which is used to mix moderate or higher quality lube oils. Technical specifications for products of this grade are better than the same kind of other domestic and foreign products.
J-0010 has a smaller molecular weight and a better shearing stability than J-0030.The product needs no degradation and is directly used for mixing higher quality lube oils.
