○ Development of bio-degradable hydraulic oil using polyolester base oils.
○ It has proved quality and market price competitiveness by develop-cooperation with Daewoo Heavy Industries and Machineries and Korea Automotive Technology Institute.
○ Contribution of bio-degradable oil keep the working environment clean and increase export competitiveness in European market.
○ Our new product of bio-degradable oils satisfy the European regulations(OECD 302B) and shows excellent performance in compare with European products.
Efficiency
○ Removes cylinder noise problem(SAE NO.2)
○ Development of longer life hydraulic oil. (oil exchange term increases to 4000 hr above)
○ Reduce the discoloration in hydraulic cylinder : Improves thermal and chemical stability.
Increase anti-wear resistance
○ Replaceable to environment-friendly hydraulic oil in heavy duty machineries
Details of Technology & Product
Our new products are proved in BFB Belgium by the method of OECD301B.
Test sample A : 67.0% at OECD301B
Test sample B : 63.6% at OECD301B
Test sample C : 69.2% at OECD301B
Test sample D : 74.2% at OECD301B
The result shows almost equivalent performance in bio-degradability. Other major characteristics in related to hydraulic oils show excellent performance for comparing with conventional mineral oil.
