Rocol BIO-SPL is a specially formulated biodegradable oil for use on Railway Switch Plates.

When tested to the internationally recognised CEC-L-32-T-82 Biodegradability Test, Rocol BIO-SPL shows greater than 90% oil loss within 21 days which indicates that the product will readily break down in the soil and is therefore regarded as biodegradable. 

Upon drying a lubricious, thin film is left on the chair which provides excellent long term lubrication.
