Castrol Optileb™ CH (previously named Viscoleb) are chain lubricants especially developed to meet the requirements of the food and beverage industries. They are water-resistant and have a high load carrying capacity. Optileb CH are tasteless and odorless oils. Special additives specifically protect from wear and prevent corrosion. Optileb CH chain lubricants are NSF H1 authorized and therefore suited for applications where a direct exposure of the lubricated part to the edible product is possible due to technical reasons.
