Description
The series of ethylene-propylene copolymer (OCP) including T612, T612A, T613 and T614 are efficient viscosity index improvers. T612, T612A have excellent thermal stability and chemical stability, and could also increase the adhesive properties and viscosity index of lubricating oils, preventing dripping and splashing during operation. This reduces operational cost and the risk of environmental contamination.T612, T612A also have good compatibility with pour point depressants. This product is primarily used in formulating multi-grade gasoline engine oils.
Recommended dosage
The dosages of T612A generally recommended to blend lubricants are 5-10%
