MSDS

PDS

Shell Naturelle S4 Stern Tube Fluid is a non-emulsifying synthetic fluid specifically developed for use in stern tubes. Manufactured from fully saturated esters, Shell Naturelle S4 Stern Tube Fluid is designed to offer superior lubrication performance whilst also being readily biodegradable with low ecotoxicity. Shell Naturelle S4 Stern Tube Fluid is an Environmentally Acceptable Lubricant (EAL) according to the definitions of the US EPA 2013 Vessel General Permit (VGP).

Features

• High viscosity index - Provides low torque system start up at lower temperatures and maintains fluid film thickness at higher operating temperatures.
• Longer service life - Fully saturated esters ensure excellent resistance to oxidation and hydrolysis while offering high temperature thermal stability.
• Increased wear protection - Advanced ashless (zinc-free) additives provide protection over a wide range of conditions.
• Maintaining system efficiency - Superior load carrying properties are coupled with excellent demulsibility (water separation) characteristics to reduce consumption.
• Readily biodegradable - Shell Naturelle Stern Tube Fluid is biodegraded by over 60% after 28 days in the OECD 301 bio degradation test.
• Low toxicity towards the environment Reduced impact from accidental discharge into the environment. Shell Naturelle S4 Stern Tube Fluid is classified as ‘not harmful’ to bacteria, algae, freshwater and marine invertebrates, and fish when tested as wateraccommodated fractions (WAFs) according to OECD and EPA test guidelines.
• Recommended for use in environmentally sensitive areas - Shell Naturelle S4 Stern Tube Fluid is an ‘environmentally acceptable lubricant’ as defined by the US EPA 2013 Vessel General Permit and offers reduced harm when used in marine environments compared to conventional mineral oils. It has a reduced environmental impact in the event of a leak or accidental spillage. It is particularly suited for use in environmentally sensitive areas.
