There are many applications where the risk of spillage of hydraulic oils in the environment is high. The development of a range of biodegradable hydraulic oils using different type of base oils and additive technologies has resulted in Matrix being able to supply suitable biodegradable hydraulic oil for most applications. Besides the use of biodegradable esters in the Ecomax SE line Matrix was able to develop a product (Hydromax HT ECO) with the highest sustainability taking eco toxicity, biodegradability and lifetime into consideration.
